Another endgame

Earlier in the season I'd been a little lucky to agree a draw in a rook ending, with both players failing to notice that the pawn ending they were about to enter was won for Opponent.

In this game I actually went into the losing pawn endgame - and was again lucky enough to get away with it.



I strongly suspect that all of the last four moves have been half-point blunders and in this position 33. a4? almost certainly is (I think that 33. axb4 holds). After 33. ... Rxd5 34. Rxd5+ Kxd5 35. h4



... Opponent played 35 ... gxh4?, missing a win that I'm tempted to describe as "study-like". Correct is 35. ... c4 36. bxc4+ Ke6!



In the game position with the g-pawns exchanged, 37. ... Ke6? loses easily to 38. Ke3, when white has the b-pawn covered and black cannot stop both the c-pawn and the h-pawn. However with the g-pawns still on the board, the line goes 37. Ke3 b3 38. Kd2 b2 39. Kc2 f4!



and black wins.

Inactivity

When I was last here, some months ago, my chess was going rather well. Results from the second half of the season, though, were distinctly less good - I reckon that I lost about a dozen (ECF) grading points by continuing to play from April onwards.

Obviously it's not all about the grades, but while I'm on the topic... I see that the online database claims that I played 26 games last season. I can only find 25. I wonder how I did in that bonus game.

So anyway, I'd better start working my way through the backlog - here's the first of several more-or-less disappointing games.

If I remember rightly Opponent offered a draw at move 13 or thereabouts, which I turned down mostly on the grounds that it was a bit early for that sort of thing. Instead I went wrong almost immediately with 14. ... e5?. It's a doubly bad move; tactically speaking I'd stopped too soon (at 18. ... exf3, failing to notice that 19. Bxf3 hit my knight), but in any case it doesn't now look like the sort of move that Black should be playing even if it were not an outright blunder. A definite case of trying too hard to make something happen - perhaps the draw offer was a cunning piece of provocation all along!
