One of the skills needed to be a good chess player is to understand your strengths and weaknesses as well as those of your opponent.  IM James Morris has just had a very successful tournament at Ballarat scoring 6.5/7, and he won the tournament by aiming for complicated positions where he could demonstrate his tactical flair whilst his opponents only became more confused.

I followed with interest his game as White against Lee Jones and when James’ 25th move (25.Ng7) came up on the screen I could only presume that it was a clerical error!   True, it was a blunder, but it resulted in a messy position that suited James and eventually the players arrived at the position in the diagram with Black to move.

Play continued 42…Ra6 43.Rff7 Rxa2.  In this sequence of moves White had missed a winning opportunity and Black had made a big blunder.   Today’s puzzle is what was Black’s blunder and what was the opportunity that White missed?


Black’s 43…Rxa2?? allowed mate in one with 44.Rb8#.  He should have asked himself “what my opponent will reply” before making his move.

White’s 43…Rff7 was not the best as Black can reply 43…Kc8 and struggle on but 43.Rb8+ would have picked up a rook after 43…Kd7 44.Rd1+.

At least things still worked out well for James.  Hopefully this good result will signify a leap forward for the young IM who is battling with Bobby Cheng to be our most promising young player.
