Yusupov Challenge: Book 1 Final Test & Summary

I have completed the final test in book 1.  As with the other chapters, I didn’t find it overly difficult, though I did make several silly mistakes.  I attribute these mostly to lapses in concentration and impatience, which is something I definitely need to guard against in my games.

Time spent: 1 hour 55 minutes (1 hour 35 solving, 10 marking/reviewing)

Score: 40/47

My average times and scores for the whole book (excluding the final test) are below.  If you have also completed the book, let me know your averages and rating and I can compile a dataset which should give chess players of all levels starting the book in the future an idea of what to expect.

Average time per chapter: 1 hour 17 minutes

Average chapter score: 89%

All in all, the book was a bit easier than what would perhaps be optimal training material for my level (currently 2048 FIDE), but it did serve as a useful refresher and I intend to be thorough and work my way through the whole series.

I have started on book 2 (Boost Your Chess 1), but will save an update on that for another post.

Yusupov Challenge: Book 1 complete

I have finally worked my way through all the instructional chapters of book 1, with just the final exam left to complete. My progress has not been as fast as anticipated, but I hope those readers who are also doing the challenge are managing to stay on track.

Book 1, Chapter 18

This chapter was about calculating forced variations.  I found some of the calculations a bit of a grind, but managed to complete them accurately in the end, dropping just one point.

Time spent: 1 hour 55 minutes (35 reading, 70 solving, 10 marking/reviewing)

Score: 22/23

Book 1, Chapter 19

The theme here was combinations to promote a pawn.  As with some previous chapters, the topic led me to the answer quite easily in most cases, but I did learn one useful motif which I wasn’t really aware of before: namely that of attacking a knight on the 8th rank with a pawn on the 7th, thereby threatening to promote in two ways.  This particular vulnerability of the knight also seems to work one rank further back (with the pawn on the 6th/3rd rank) if the knight is on b2, g2, g7 or b7.

Time spent: 1 hour 5 minutes (20 reading, 40 solving, 5 marking)

Score: 20/20

Book 1, Chapter 20

Weak points was the topic of this chapter, with some nice strategic examples from the classics to illustrate it.  I tried not to overthink the solutions, just scanning the position for a weak square and trying to find a natural way to exploit it, rather than attempting to calculate exhaustively.  The approach worked pretty well, and I think is the right way to go in this sort of position in a practical game, though I did drop a couple of points on exercise 20-9.

Time spent: 1 hour 15 minutes (30 reading, 45 solving, 5 marking)

Score: 21/23

Book 1, Chapter 21

More pawn combinations.  I went for Ne8+ rather than the book’s Be7 on exercise 21-7, but as my variation is also clearly winning I didn’t deduct points.

Time spent: 55 minutes (10 reading, 35 solving, 10 marking)

Score: 19/19

Book 1, Chapter 22

This was a useful chapter for me, as it digs deep into the idea of a ‘wrong-coloured’ bishop in endings with a rook pawn.  Whilst the basic fortress (shown in the diagram below) is straightforward once you know it, there are some nice nuances in reaching it.

Time spent: 1 hour 10 minutes (20 reading, 45 solving, 5 marking)

Score: 24/25

Book 1, Chapter 23

No matter how many times I see smothered mate, it never fails to bring a smile to my face.  This chapter introduced a few fresh examples.  I’ve yet to get this in an over-the-board game, but have done in online blitz.  Let me know in the comments below if you have had the opportunity to give smothered mate.

Time spent: 55 minutes (10 reading, 40 solving, 5 marking)

Score: 17/19

Book 1, Chapter 24

Despite playing the open games for the entirety of my chess career to date, there are still plenty of gambits which make me uncomfortable.  That was the topic of this chapter, and I dropped a lot of points (though this was likely in part due to fatigue).  I may return to this chapter at some point, and certainly need to brush up on my opening theory in a number of gambits.

Time spent: 55 minutes (15 reading, 35 solving, 5 marking)

Score: 15/21

Those of you who are doing the challenge, or have completed the chapters I have written about here, do let me know how you got on / are getting on in the comments below.

Yusupov Challenge, week 6

Another busy week, in which I managed to complete three chapters.  I am about three quarters of the way through the first book now, which is not as far as I had hoped I would be, but I imagine a lot further than I would be if I hadn’t started this challenge.  I am going to try switching to solving in the mornings before work, when my brain will hopefully be a little fresher than after.

Book 1, Chapter 15

This chapter is about combinations, and features fairly standard tactics problems.  Some of the exercises took me a while, but I did manage to get almost all right.  The exception was 15-3, where I chose Bxc5, which should still be winning or at least much better for White, but is much less convincing than the (with hindsight rather obvious) solution, Rd8+!

Time spent: 1 hour 50 minutes (35 reading, 65 solving, 10 marking/reviewing)

Score: 21/22

Book 1, Chapter 16

It’s amazing how complex and interesting positions with only four pieces (including kings) left on the board can be!  This chapter is about queen vs pawn (on the 7th), and I found some of the mate/stalemate motifs really pleasing.  The only exercise I dropped points on was 16-4, which with hindsight is laughably simple.

It is White to play and win.  I immediately noticed that after Qb3+ Ka1 White does not have to worry about stalemate straight away, as Black still has his h-pawn.  However, I only thought about using the extra tempi to bring White’s king closer to the a-pawn.  As it is clearly too far away for this plan to work, I gave up and assumed it was a draw.  In fact White mates with the simple 2. Qc2 h2 3. Qc1#

16-8 is a real treat, which I was pleased to solve correctly, but I will leave that position for people who have the book.

Time spent: 1 hour 20 minutes (10 reading, 60 solving, 10 marking/reviewing)

Score: 27/29

Book 1, Chapter 17

This chapter is about stalemate motifs.  As with some of the earlier chapters, the theme is so well defined that it makes finding the solution quite straightforward in most cases, and I managed to get them all right.  The most challenging was 17-2, for good reason – whilst the ‘solution’ given in the book is the best try, it doesn’t actually work with best play!


I ‘found’ Bg4, where the book gives only Nxg4 stalemate.  I wasn’t sure what was going on after Nc6 (or even Bf6, which is still a draw, but worth a try rather than giving immediate stalemate).  It turns out that Black’s knight can dance around and eventually give mate, despite the White bishop’s best efforts to defend the key squares.  Hopefully this will be corrected in a future edition.

Time spent: 1 hour (15 reading, 30 solving, 15 marking/reviewing)

Score: 15/15

Those of you who are doing this challenge with me, let me know how you got on this week in the comments below.

Yusupov Challenge, weeks 3-5

As expected, week 3 was a write-off, due to having too many evening matches.  Unfortunately week 4 went the same way, as I was ill at the start and then had to work night shifts later.  Week 5 has been much more productive, with five chapters completed in spite of having two mid-week matches.  That means I am slightly under half a book behind the pace set on the Quality Chess blog, but I may be able to catch up over the coming month.  For those who haven’t seen it, Artur himself has now given his thoughts on the challenge, providing those of us doing it with an extra boost of motivation.

Book 1, Chapter 10

This is another pawn ending chapter, talking about the opposition.  I was expecting to ace the exercises, as a lot of them were similar to those in the first chapter of Dvoretsky’s Endgame Manual, but I carelessly missed a few details, dropping four points.

Time spent: 1 hour 10 minutes (10 reading, 50 solving, 10 marking/reviewing)

Score: 22/26

Book 1, Chapter 11

The topic of this chapter is the pin – a tactic players become familiar with very early on – and unsurprisingly it was fairly straightforward.  I still dropped a couple of points on the last exercise, missing that after my proposed solution of Bxc5 Rxc5 Qd4 Qc7 Qxc7 Qxc7 Qxb4, Black escapes with a perpetual check.

Time spent: 55 minutes (25 reading, 25 solving, 5 marking)

Score: 19/21

Book 1, Chapter 12

Another chapter on an elementary tactical motif – the double attack.  The exercises were once again fairly easy for me, but I still dropped two points.

Time spent: 50 minutes (20 reading, 25 solving, 5 marking)

Score: 15/17

Book 1, Chapter 13

The topic of this chapter, ‘Realising a material advantage’, was very interesting for me, as it is something I routinely struggle to do.  Some of the exercises required careful thought, though I eventually managed to solve most of them.  The only exception was 13-6, though I feel a little robbed here, as my solution (Re7) also seems to be winning but is not mentioned in the book.  If anyone knows of more exercises available anywhere on this theme, please let me know in the comments section below.

Time spent: 1 hour 30 minutes (20 minutes reading, 60 solving, 10 marking)

Score: 19/21

Book 1, Chapter 14

This chapter deal with open files and ‘outposts’ on them.  ‘Outpost’ in this context seems to mean ‘square on an open file defended by a pawn, and not able to be attacked by an enemy pawn’.  The idea of occupying outposts on open files is not as ingrained in me as some other strategic ideas, so it was a useful read.  I recently failed to make use of just such an outpost in one of my games (Taylor – Jaszkiwskyj, Middlesex vs Essex 2017):

Here Rc5 is the best move, keeping control of the open file, and if Black captures with Rxc5 then dxc5 give White a protected passed pawn and a useful square on d4 for the knight.  Instead I played the planless Rc3 (I was very low on time), and my opponent played Rxc3, missing the chance to occupy his own outpost with Rc4!?  This is a more difficult move to make, as it sacrifices an exchange, but after Bxc4 dxc4 Black has great practical chances along the a8-h1 diagonal, as well as a protected passed pawn on c4.

Having completed this chapter, I hope I will make the right move automatically the next time I get a position like this.

Time spent: 1 hour 5 minutes (20 reading, 40 solving, 5 marking)

Score: 16/20

I feel a bit fortunate to have dropped only four points, as I was tired and impatient and so rushed a bit on some of the exercises.

There’s still time to join the challenge, so comment below if you would like to.

Yusupov Challenge, week 2

I completed five chapters in week 2 of the Yusupov Challenge – one short of the target of six.  As mentioned previously, I am doing one chapter a day after work, except when I have an evening league match; as I have five games this week, the chance of me getting six done in week 3 is negligible.  The main thing is that I continue to make good progress and work on the book whenever I realistically can, and I am not going to get too hung up on whether or not I managed six in a week.

Book 1, Chapter 5

This chapter is on double check, and the rather specific topic makes looking for candidate solutions to the problems quite straightforward.  Even so, 5-7 tripped me up, as I revealed check in the wrong way (2. Nh5 ++ rather than 2. Ne8 ++).  This still wins, but I deserved to lose  point as I went astray further down the line, putting my queen en prise.

Time spent: 60 minutes (20 reading, 25 solving, 15 marking/reviewing)

Score: 15/16

Book 1, Chapter 6

An interesting chapter on the relative value of the pieces.  Yusupov comes up with his own value for the rook – 4.5 rather than the usual 5 – which better accounts for facts like rook and pawn generally being inferior to two minor pieces, but fails to account for the fact that two rooks are more often than not better than a queen.  At the end of the day, fixed numerical values for the pieces will only ever be an approximation, as their value shifts according to factors which Yusupov discusses.

Time spent: 1 hour 35 minutes (30 minutes reading, 50 solving, 15 marking/reviewing)

Score: 14/19

These exercises were tougher than in previous chapters, though I did feel a little hard done by as the marking scheme penalised me a couple of times even though my selections were also strong.

Book 1, Chapter 7

A chapter on discovered attacks – as with chapter 5, the topic leads you to the answer in most cases.

Time spent: 40 minutes (15 reading, 20 solving, 5 marking)

Score: 15/15

Book 1, Chapter 8

There has been much talk in the official challenge thread about players of various levels skipping books, and starting later in the series.  Chapters like this one convince me that the vast majority of players should start from the beginning.  The topic is ‘centralising the pieces’, and the exercises are based on the idea of moving your pieces to central squares or somehow taking advantage of your centralised pieces.  Not all of them are ‘find the tactical knockout blow’ type exercises; some simply require you to find the best move, which makes them more like a real game and rather more difficult.

Time spent: 2 hours 5 minutes (30 minutes reading, 1 hour 20 minutes solving, 15 minutes marking)

Score: 16/27

I bled points all over the place here.  The pass mark is 12, so I still passed reasonably comfortably, but I am planning to return and review this chapter at some point.

Book 1, Chapter 9

The topic is mate in two, and the idea is to train the skill of accurately calculating short variations without missing candidates.  The exercises are of the non-game-like problem type, and I found I either stumbled upon the solution quite quickly, or ended up staring at them for ages in increasing disbelief that a solution really existed.  I had to do it in several sessions, and even then I gave up on two.

Time spent: 2 hours 25 minutes (30 minutes reading, 1 hour 50 minutes solving, 5 minutes marking)

Score: 10/12

Yusupov Challenge, week 1

I have completed week 1 of the Yusupov Challenge, doing four chapters rather than the usual six as it started partway through the week.  Finding time to do a chapter almost every day is going to be challenging at times, but that’s why it’s called a challenge!  I am doing a chapter every day after work, except when I have evening league matches, as I want to be fresh for the game.  In weeks where I have more than one evening match I will try to fit in the missed chapters at the weekend.

Book 1, Chapter 2

This is another chapter on mating patterns, and is a little tougher than the first chapter, but still not too difficult as all the patterns seen in the exercises are introduced beforehand.

Time spent: 65 minutes (30 reading, 25 solving, 10 marking and reviewing)

Score: 19/20

I dropped a point on 2-4, choosing 2. Rh4 rather than 2. Qh6 – the right idea, but unfortunately my move order allows a perpetual.

Book 1, Chapter 3

A chapter on basic opening principles.  The topics covered are rapid development and controlling the centre – concepts which every chess player is introduced to early on – so I was not expecting it to be too difficult, but in fact it was by far the most challenging chapter so far.  I was reading it on a train – not having a board to hand made following all the variations in the introduction difficult, and the screaming baby did not help particularly with the exercises.

Time spent:  2 hours 40 minutes (25 minutes reading, 1 hour 50 minutes solving, 25 minutes marking and reviewing)

Score: 22/31

I dropped points onn 3-2, 3-7, 3-10 and 3-12.

Book 1, Chapter 4

This chapter on basic pawn endings proved fairly straightforward to me, as I have studied pawn endings before (it’s the only chapter of Dvoretsky I’ve managed to (half-)complete).

Time spent: 50 minutes (15 reading, 30 solving, 5 marking)

Score: 22/22 🙂

Most of my solving time was spent on 4-5, which required a lot of calculation.

There’s still time to jump on board if anyone else wants to join the challenge (either at my rapid pace or at their own pace) – just post in the comments below and in the Quality Chess thread.

Yusupov Challenge

I’m back, and ready for a new challenge.  Quality Chess are running the ‘Yusupov Challenge’, with the aim being to work through six chapters of Yusupov’s award-winning instructional series per week.  I received the whole series for my last birthday and have been meaning to get stuck in to them, so this fits in nicely with my plans.  If any readers would like to join me in the challenge (either at six chapters per week or at a pace which suits them) I would be delighted!  You can sign up here.

I will be writing a short post on this blog to mark each chapter completed, sharing my score and the approximate time I spent, which has been the subject of much debate on the Quality Chess blog.  Notes on the first chapter below.

Book 1, Chapter 1

I rattled through this chapter in about 50 minutes – 20 minutes reading the thematic introduction, and 30 minutes solving the puzzles.  Most of the puzzle solving time was setting the positions up on a board rather than actually solving them, though I did spend a few minutes on 1-9 and 1-10.  I didn’t bother to set the pieces up for the positions in the introduction.

I scored 14 out of a possible 16 points on the exercises, losing two points on 1-10.  Although I chose the correct first move (1…Ng3), I carelessly completely overlooked Black’s main reply (2. Qxd4).  In 1-9 I chose to exchange rooks in a subvariation (1…Kg7 2. Nxf8+ Kxf8 and now instead of the immediate 3. Nxh7+ I chose 3. Rf8+ Kf7 4. Rxa8 Nxa8 5. Nxh7), but as the ending looks to be winning anyway I haven’t deducted points.

For anyone else doing the challenge, let me know how you got on with the first chapter below.

General update: Blog regulars will by now be used to months-long gaps in my posting.  Rest assured that I have been playing lots of chess in the interim, though my studying has not been going as well.  The blogging has suffered as my planned ‘Road to 2100 Lessons Learned’ series has fallen victim to scope creep and perfectionism, the result being that it has yet to materialise at all.  I will refrain from making promises about when it might finally appear; hopefully it will be a pleasant surprise for you when it does.

In other news, I have for the first time managed to qualify for the main section of the British Championship in July/August.  I am very excited about getting to play in the same section as the absolute elite in this country (Mickey Adams won it last year), and training for that will be my focus for the next few months.
