Mark Kernighan - Greg Tomkovich [D56]
KCC Summer Tourney/Kenilworth, NJ USA (9) 2005
Too weakening of e5. White's plan now is to finish development and then move his Knight at f3 to allow Pf3, kicking the Black Knight back, followed by e3-e4 with a much better game.
A temporizing move, hoping Black wil play Ndf6 allowing Ne5!
White has a growing space advantage.
It is a mistake to open the f-file, which becomes the main avenue for White's attack.
Necessary was 23... Qe8 - now Black can force mate.
