More From My Games

I played a few games in the past couple of weeks. First of all, I played at the first weekend of the 4NCL 2010-11 season (British team league). My team did very well as we won both matches. If we continue like this we should end up in the top half of the 1st division after 7 rounds. For the past two years we were the winners of the bottom half and felt we could do better. I did ok by drawing both of my games against similarly rated opponents, but I could have posed more problems for both of my opponents. Unfortunately, getting into the time trouble didn't help - I need to sort that out!

I also played a game for Hackney 1 team in the top division of the London League. We were outrated by our opponents Wood Green on every board (apart from the bottom borad 12 which was unrated), but somehow we managed to draw the match! Unfortunately, I lost my game against strong IM Mohamed Tissir on board 5 but not without missing some winning chances on my side. The time limit is fairly fast in the London League - 1hr 15mins for 30 moves followed by 15mins to finish and that again proved to be the deciding factor for me. With maybe a minute left on the clock I managed to miss an easy draw and a less easy win in this position - how annoying! Think about how you would have played in this position, black to move. I will provide the solution in the next post.

M. Tissir (226 ECF/2474 FIDE) - M. Yurenok (178 ECF/2071 FIDE)
Wood Green - Hackney 1
London League, 10th November 2010

There' been a lot of exciting chess going on recently with the Tal Memorial and the blitz afterwards. I'm glad that Sergey Karjakin got a share of the first prize with Levon Aronian in the main tournament. Aronian did very well to win the blitz tournament as well. I wish I had more time to watch the games - but can't do that during working hours! Currently I'm following the Russian Women's Superfinal Championship. Nadezhda Kosintseva is leading with 3.5 out of 4.

Now it's time to reveal the solution for the position published in the last post. Some of you might have noticed that the correct solution was already suggested in the comments to the last post. So here is the position again:

N. Relea (2193) - M. Yurenok (2071)
Cap d'Agde, 27th October 2010

I should have played:

52...Kh5! - it's not easy to let go of conventions and see that attacking with the king wins here even with queens and rooks present! White has two options:

53. Rg5+ Qxg5! 54. hxg5+ Rh4 55. Qxh4 Kxh4 and this pawn endgame is winning for black because white can't do anything with his extra pawn on the queenside. For example: 56. Kg2 Kxg5 57. Kg3 Kh5 58. Kh3 g5 59. Kg3 g4 60. Kg2 Kh4 61. b4 g3 62. Kg1 Kh3 63. Kh1 g2+ 64. Kg1 Kg3 65. c3 dxc3 and black checkmates in two.


53. Rxf4 Qxf4+ 54. Kg2 (or 54. Kg1 Qg4+) Qxh4 55. Qf3+ Qg4+ and white can't avoid exchange of queens leading again to the won pawn ending for black.

I also promised to show you an interesting double rook endgame  from another one of my games in Cap d'Agde. I know a lot of people think that endgames are boring, but double rook endgames are notoriously complex. This example is no exception, besides I think it's quite entertaining as both sides are trying to queen their pawns. Have a look at this position, black to move:

S. Pham Guerrero (2199) - M. Yurenok (2071)
Cap d'Agde, 29th October 2010

Earlier on white's endgame was quite a bit better, but he was probably trying to win too hard and allowed me to have substantial counterplay on the kingside. Here I played 42...Re3! White thought for quite a while as I guess he realised that he was now in trouble and he responded with the only move 43. b6 But even after this move black is winning. Try to find black's next move and the supporting variations leading to a win. I suggest you analyse it with the board as there are several rather complicated variations, but if you can calculate it all in your head - well done! I wasn't able to find the correct continuation and only drew the game. I hope you'll enjoy analysing this and I'll tell you what should have happened in my game in my next post.

In the game M. Tissir - M. Yurenok I would have played 1.Qf6, intending Qf1 or taking white a pawn.

White Knight is forking Queen and Rook. It seems a Queen move is mandatory. If White doesn't capture the rook, playing 1...Kg1, for instance, Black material advantage is winning.

I could not find the solution in one minute: I spent my time trying to trap white Queen. When I realized there was a fork, the solution (it it is correct) suddenly came up.

Hi Alberto,
1...Qf6 only achieves a draw with the perpetual, but I should have seen this as it's fairly simple. The winning move is a bit more complicated :)

I like looking at endgames - will wait till your next post to discover the solution to this one though :)

Hi sixko,
That's great! I hope you'll enjoy the solution which I'm about to post.

Hi Anonymous,
Good question about the Women's World Championship - I'll elaborate shortly in my next post.
