About the British

As I said in the last post, I was going to play in the 4NCL rapidplay. I found 10min +10sec increment after each move to be closer to blitz than rapidplay and quite difficult, while the previously reported Golders Green rapidplay had 30 mins for the whole game that I preferred. I perform worst with very short time limits. Nevertheless, it was fun with the team event on the Saturday (I played for Hackney on board 4 of 4) and the individual event on the Sunday. I had some peculiar moments happen to me like not capturing a piece that I attacked with a pawn a move before (I had about 2 mins left so not really short of time!) and also accidentally grabbing the wrong piece in the opening (queen instead of bishop next to it!).

Now let me tell you about my performance at the British Championship that was held in Sheffield at the end of July/beginning of August. I qualified for it two years ago through my rating performance at the 4NCL, but as I wasn't able to play last year I carried my place over to this year. I'd never played in the British before and I really enjoyed my first time there. It's a shame it takes whole two weeks from my holiday allowance at work, so it's not something I can do every year.

Sheffield isn't quite the summer holiday destination but from chess point of view it suited me very well. In the past, I'd spent quite a lot of time in Sheffield for my work, so I knew my way around a bit. My tournament started rather badly as I lost my first two games, but I didn't get too worried as it was an 11 round tournament and I didn't think I was playing badly. In the following 5 games I got 4 points, including a win against IM Susan Lalic, a draw against my 4NCL team mate FM Laurence Webb and a draw against another strong FM David Eggleston. I got stopped by another one of my 4NCL team mates IM Adam Hunt before finishing with 1.5 in the last 3 games. So the end result of 50% and 2208 performance got me some rating points, but it would have been even better if I got another WIM norm. I had to win in either of my last two games to achieve it and was very close to it in both games, but ended up only getting 1/2 out of the last 2 games. I have qualified for the next year's British Championship through this performance, but it clashes with London 2012 Olympics in my home city!

Anyway, here are some interesting moments form my games. I was nicely surprised to hear that this puzzle from my game was published in the Daily Telegraph - the national newspaper in the UK. White to move. This one took me seconds to find, so I hope you can see it too.

The British Championship, 30th July 2011


As I had plenty of time, I spent a little while checking that the move that I saw actually worked. I found no refutation, so I played:

25.Be5! the queen is overloaded so I win an exchange 25...Qxe5 26. Rxc6 Rb2? this just makes things easier for me as I can now force exchange of queens 27. Qc3 Qxc3 28. Rxc3 +- and I eventually won with the extra material.

The next diagram is from my game against a strong blind player Chris Ross. I've never played against blind players before and found it quite amazing that my opponent was playing as well as me while I can see the board and he can't. I was better for much of the game but at the end couldn't close it off. I had an immediate win in the following position, which I didn't notice possibly due to being in time-trouble. If I won this game, I would have almost certainly got a WIM norm because I would have been paired with a very strong opponent the next day making my final game result irrelevant. Can you find the white's move that I didn't?

The British Championship, 4th August 2011


I played 33. Bb6? losing all my advantage and the game soon ended in a draw. The correct move was:

33. Bd6! (33.Bd4 also works with the same idea) on the one hand it's a discovered attack of the white rook on the c7 knight, while on the other hand it's interference between the black queen and the rook

33...Qxd6 (33...Rxd6 34. Rxc7 +- winning the queen for a rook)

34.Rxc7+ Kg6 (34...Ke6 35. Rc6 +-winning the queen for a rook again)

35. Rxg7+ Kf5 36. Qc8+ Ke4 (36...Qe6 37. g4+ winning) 37. Rg4+ Kd5 38. Qc4 #


And finally, here is the position from my last game in the tournament. To get a WIM norm I had to win this game with black against young and progressing FM opponent from Ireland. I managed to complicate things considerably in the middlegame, which caused both of us to be in significant time trouble in the very complicated endgame with queens and bishops, below. I'm two pawns down but have sufficient compensation due to white's b2 bishop being out of play while his king's position is rather open. My king isn't particularly safe either, but I'm the first to attack, black to move.

RR. Griffiths (2301) - M. Yurenok (2090)
The British Championship, 5th August, 2011


Objectively, this position is actually a draw. I went astray and lost it in a few moves. However, if I played:

33...Qe1! this would have left my opponent with finding the only move to save his game while his seconds were ticking down. Not an easy task, especially since white's only move isn't that obvious at all. During after-game analysis both of us couldn't find an adequate reply for white until one of the observers pointed it out. Black's idea is to play Be3-f4 manoeuvre, winning if white doesn't do anything special. The only move for white to save the game is:

34.Qh1! and black has nothing better than to repeat the moves with 34...Qd2+ 35. Qg2 Qe1 =


You can check for yourself that with correct play for black none of the other moves work for white apart from 34. Qh1. There is a number of variations to consider and, of course, they are not easy to play correctly for black especially in time trouble. One example variation goes like this:


34. a4 Be3 35. h4 Bf4+ 36. Kh3 Bg6! (seemingly the only winning move) 37. Bf3 Bd3! 38. Be2 Be4 39. Bf3 Qe3! 40. Bc1 Bxf3 41. Bxe3 Bxg2+ 42. Kxg2 Bxe3 -+

Anyhow, the original position is very interesting for analysis!

Now I'm off to the European Team Championship in Greece on Wednesday. Wish me luck!

Pacific Coast Open

I'm back from the USA and suffering from jet-lag. However, there's a million things to do after being away for 3 weeks and on top of that I am going back to work on Friday, for the first time after 10 months of sabbatical! I'm so glad that BT gave me this opportunity to take the sabbatical as I think I had the best 10 months ever despite some low points at some chess tournaments.

My Pacific Coast Open tournament ended fairly well as I got 3.5 points out of 6 (including a half-point bye) drawing last two games against stronger opponents. Unfortunately, I wasn't able to win one of those games with an extra pawn! And I ended up half a point behind a large rating prize. I don't know why in the USA they have very large rating prizes - it was larger than a second place prize! Nevertheless, I'm happy to add another 9 rating points to my FIDE rating despite a slow start to the tournament. My partner IM Simon Ansell did very well by getting a share of the second prize. You can see the final standings here: http://www.chesstour.com/pco10r.htm I didn't have any exciting games to show although I haven't had a chance to analyse them in detail and may yet find something worth showing at a deeper level. I bought a new laptop in the USA so I hope my Rybka will now run even better and faster! 

New FIDE ratings have come out at the beginning of July and I'm back to over 2000 mark at 2062. ECF ratings have come out as well and I am now rated 178 - a bit higher than a year ago but lower than I believe my current strength is. Unfortunately, ECF ratings are published only once a year and can be a bit misleading for an improving player. British Championship has started on Monday and will keep me entertained for the next 2 weeks. The top seed GM Mickey Adams is the favourite to win the title. Unfortunately, there are only 3 women participating (I decided against playing because of going back to work) so I hope ECF would do something to encourage more women to play in the British.

I haven't got any firm plans for my next chess tournament but I am considering playing my next tournament at the Berks & Bucks congress during the August Bank Holiday weekend. It's a 6-round FIDE-rated tournament. I'll just have to see how tired I'll get being back at work and if I need my weekends to recover rather than play chess! I am also hoping to play in the 9-round FIDE open at Cap D'Agde in the South of France in October.

Interesting Game in QGD

The 2009-10 4NCL season finished over the weekend. After 7 rounds all teams in the 1st division get re-shuffled into the "championship" pool and the "demotion" pool based on their performance up till then. My team Betsson.com did exactly the same as last year - we ended up in the "demotion" half but we won the "demotion" half again and stayed in the 1st division for the next season. Here I am in the final game of the weekend which I won. I was the last to finish in the match and my game decided our top position in the "demotion" half. The photo is courtesy of Steve Connor from the Atticus Chess Club.



I felt pretty ill at the start of the weekend but still got 2 out of 3. My performance throughout the season was 2202 earning me 31 rating points. I've also found out that this performance qualifies me for the British Championship in the summer so I'm quite happy about this achievement! I've never qualified before (at least I'm not aware if I did as rules seem to change from year to year). However, at the moment I don't plan to play in the British Championship as I will be back to work and would prefer to spend my holiday allowance on something that is not as long. Normally, British Championship results are considered by the England team selectors for either European Team Championship or the Olympiad later in that year. However, this isn't the case this year because the Olympiad is quite early in the Autumn, meaning that the England team selection has to happen before the British Championship. So this year there don't seem to be any special benefits for me playing in the British Championship as compared to any Open tournament.

As promised, here is my analysis of an interesting game I played in the Thailand Open. It was the 8th round and also my last game of the tournament since my 9th round opponent didn't turn up. You can replay the game via an applet below, but here is the game with my commentary.

Maria Yurenok (1953) - Jan E. Frantsen Montgomery (2158)
19 April 2010, Thailand Open

1. d4 Nf6 2. c4 e6 3. Nc3 d5 4. cxd5 exd5 5. Bg5 Nbd7 6. e3 c6 7. Bd3 Bd6 - this is Queen's Gambit Declined Exchange Variation (D35) but 7...Be7 is a lot more common set-up.

8. Qc2 Nf8 9. Nf3 Ng6 10. h3 - maybe a bit timid from me. There is not a lot of theory on this particular variation, but looking through my Mega Database white's more common 10th moves include Nh4, 0-0-0 and h4.

10...O-O 11. O-O h6 - I thought for a long time here as I didn't fancy any of white's moves that much, so eventually I went for what I thought was the best option even if it meant giving up a piece

12. Bxh6! - I believe the resulting position is harder to play for black. My other alternative would have been 12. Bxf6 Qxf6 13. e4 dxe4 14. Nxe4 Qd8 15. Nxd6 Qxd6 =

12. Bxh6 gxh6 13. Bxg6 fxg6 14. Qxg6+ Kh8 15. Ne5! - exclamation mark because I had to see this Ne5 idea before 12.Bxh6, otherwise white is just worse. However, 15. Qxh6 first, followed by 16. Ne5 would have been more accurate as it doesn't allow 15...Qc7 and pushes the knight to an inferior square. E.g. 15. Qxh6+  Nh7 16. Ne5 Qf6 (16... Rf6 17. Qh5 Be6 18. f4 Qe7 19. g4 [19. Ng6+? Rxg6 20. Qxg6 Bxh3 -/+] Rg8 20. Kh2 - unclear) 17. Qxf6+ Rxf6 18. f4 +/=

15... Bxe5?! - it was better to play 15... Qc7 16. Qxh6+ Kg8 17. f4 Qg7 18. Qxg7+ Kxg7 19. g4 - unclear

16. Qxh6+ Nh7 17. dxe5 Qg5? - black should have kept the queens as otherwise my pawns are too strong. With the queens still on black's counterplay is around forcing white to play f4 and attacking b2 and e3 pawns with Qb6 which results in a very unclear position, e.g. 17... Qc7 18. f4 Qb6 19. Rae1 (19. Nd1 feels a bit passive though possible) Qxb2 20. Ne2 Rg8 (20...Qxa2 21. g4 - unclear) 21. g4 Bxg4 22. hxg4 Rxg4+ 23. Kf2 Rag8 24. Rh1 Rg2+ 25. Kf1 Qc2 - unclear

18. Qxg5 +/= Nxg5 19. f4 Ne4? - it's not a good idea for black to exchange knights because it cuts out any counterplay based on d4 push and instead black's e4 pawn would end up on the same colour as his bishop. Better move was 19... Nf7 20. g4 +/=

20. g4 - I failed to realise that the immediate knights exchange with 20. Nxe4 was a better move for me, e.g. 20...dxe4 21. g4 +/-

20...Nd2 21. Rf2 Nc4 22. Re1 Nxe3 - it was a bit better for black to keep the knight with 22... Re8  23. b3 Nb6 24. Rd1 +/-

23. Rxe3 d4 24. Rd3 dxc3 25. bxc3 +/- since exchanging the queens, black spent five moves with his knight instead of improving position of his pieces while I put most of my pieces into active positions.

25...Be6 26. f5 Bd5 27. e6 - it was more accurate for me to improve the position of the last piece - the king - as black has no counterplay, e.g. 27. Kh2 Rae8 28. Re3 b5 29. Kg3 a5 30. Kf4 +-

27...Rae8 28. Rd4 b5 29. g5 a5 30. h4 a4?! - at this point the best practical chance for black to make a draw would have been 30... Bxa2 31. Rxa2 Rxf5 32. Rxa5 Rxe6 33. Ra7 Re8 34. Kg2 +-

31. a3 Bxe6?! - black's cracked and given back the piece but it's hard to suggest much else as otherwise white's pawns go forward anyway. Here is an example variation: 31... Re7 32. h5 Kg8 33. h6 Ree8 34. Rff4 Kh7 35. Kf2 Rg8 36. Rg4 Ref8 37. Rdf4 Rxf5 (otherwise white's king comes forward decisively) 38. Rxf5 Bxe6 39. Rgf4 Bxf5 40. Rxf5 Kg6 41. Rc5 +-

32. fxe6 Rxf2 33. Kxf2 Rxe6 34. Kf3 Re1 35. Kf4 Rc1 36. Kf5 Kg7 37. h5? - a moment of madness from me as I started seeing ghosts. Of course, 37. Rd7 was winning straight away which for some bizarre reason I discarded. E.g. 37. Rd7+ Kf8 38. h5 Ke8 39. Rb7 and white's pawns can't be stopped. My move would have made winning a lot more difficult for me if black replied correctly. But it must have been my lucky day (you need luck sometimes even in chess!) as my opponent replied with his own mistake:

37... Rxc3? - instead black should have played 37... Rf1+ posing some technical problems for me as I was approaching time-trouble e.g. 38. Kg4 (38. Rf4? only leads to a draw after 38...Rxf4+ 39. Kxf4 c5 =) 38... Rg1+ 39. Kf4 Rf1+ 40. Ke3 Re1+ 41. Kf2 Rh1 42. Rd7+ Kh8 43. Rd8+ Kg7 44. h6+ Kg6 45. Rg8+ Kh7 46. Rg7+ Kh8 47. Re7 c5 48. Kg3 b4 49. cxb4 cxb4 50. axb4 a3 51. Ra7 Ra1 52. Kg2 threatening 53. g6 +-

38. h6+ Kf8 39. h7 Rh3 40. Kf6 Rf3+ 41. Kg6 Rh3 42. Rd8+ Ke7 43. h8=Q Rxh8 44. Rxh8 1:0 
It may not have been the perfect game but it was a bit entertaining and even GM Nigel Short liked watching it!
