More King’s Gambiteering

King

I was away on holiday with my family so my son and I have been away from chess for about a month. On our return my son had to play in a competition so I thought it would be good to watch a couple of chess videos before the tournament. One chess video was an analysis of a King’s Gambit game played by club level players. The analysis was by an IM called Danny Rensch who is no fan of the King’s gambit. He kept saying that the King’s Gambit was refuted by the move d5. This is in line with my earlier post that suggests the black defense of 1.ea e5 2.f4 d5 3.exd5 c6. Regardless of this supposed refutation I chose to play the King’s Gambit in my second game on my return to my Tuesday club. I chose to do this because my first game was very rusty; full of errors, badly recorded and with time pressure – I felt out of sorts and I wanted to sharpen things up a bit. Two good tips I had heard about for the King’s Gambit were ‘be aggressive’ and ‘aim for the f7 pawn’. I followed these principles without too much other information and it’s amazing to see how dangerous the King’s Gambit can be. Here is the game.

Following on from this I decided to google ‘King’s Gambit’ and discovered this great computer match won by white.

And an explanantion of this game here.

While we’re on the King’s Gambit I thought I’d add this line because it is named after a player called David Flude at my Sunday club. The Flude Line.

Olympiad Rollercoasters

In the dead of night I watched some live games from round 2 of the Tromso Chess Olympiad. I was watching the Australian team playing Armenia and next to the onscreen boards was a gauge that showed whether the current advantage was black or white according to stockfish. It was fun to watch the changing fortunes of each game and I have felt those changing fortunes accutely this weekend in my Friday and Sunday games. In both of these games I felt I was in a wining position but I ended up losing the Friday game and drawing the Sunday game (see Sunday game below).

At the Olympiad the round 2 Australian game with the biggest shift was the game between Max Illingworth and Sergei Movsesian.  In it Max seemed to dominate for most of the game but his attack faded away and the initiative was lost. Here is the game.

A graphical printout of the game shows that the game was ‘won’ for max.

And here is the game I played on Sunday.

And the graph for my Sunday game:

Tactic was Nxd5 (Queen is threatened and if she takes the Bishop I can ‘Royal Fork’ with the Knight and grab the Queen)

I have just resigned a game, as black, in my ICCF webserver tournament. The game included a long endgame in which I had a king, a rook and four pawns  to his king, rook and five pawns. My gut feeling is that it should have been drawn but I just wasn’t able to achieve this. I have jumped to move 29 which follows 28. …bxc5 so that I can focus on the endgame. I have put some notes into my game without using a computer. Then, at the base of this post, I have analysed the ending using a computer to play itself to see what could have happened.

I’ve looked at many different variations from move 28.bxc5 but if white plays well then I think my initial gut feeling is wrong and a draw is impossible to achieve.

COMPUTER ANALYSIS

I set up the move 29 position on SCID vs. PC software and allowed the stockfish 4 engine run for about 30 seconds before pressing enter and forcing the move. The result was this:

Maybe there was a draw but it seems very hard to achieve.

And eerily enough this puzzle popped up on chess.com
