Hi Jeroen, "You know, this game really illustrates the VERY THIN line there can be between a win or a loss" 100% agree with that! It is always a question of some centipawns in score. That was also the case in the game Gandalf -Fruit. And also during the game Gandalf - Diep. The difference between exf4?? or e4! was miniscule. Hopefully during the next tournament at Leiden, the organisation provides heart-pills, tranquillizers and other stuff ;) Kind regards, André On November 19, 2005 at 11:32:28, JNoomen wrote: >On November 19, 2005 at 03:42:13, Andre van Ark wrote: > >Hi Andre, > >Yes, you might be right. 20.a3! is of course much better than snatching the >pawn.

If Fruit would have played 19.Kb1! or I would have had 18... Qc7 >19.Kb1! in the book, everything would be in order. I also remind that Diep first >wanted to play Rfc8 instead of b3!
