notyetagm: Position after 37 e4xg6?
 click for larger viewWith his last two moves (35 ... h7-h5, 36 ... h5-h4) Geller (Black) has setup a nasty little tactical surprise for White, which 37 e4xg6? did nothing to prevent. <<<Geller has noticed that the lineup of dark-squared Black e5-bishop and White e1-queen means that the g3-square is a <TACTICAL BASE> from which the Black e5-bishop would strike at the White e1-queen. So the g3-square is a <TACTICAL BASE> and the White e1-queen a <TACTICAL TARGET>.>>> Geller knows that he must gain control of this g3-tactical base. So first he <COORDINATES HIS FORCES> on the crucial g3-square with 35 ... h7-h5 and 36 ... h5-h4. Secondly, Geller knows that he must <CLEAR THE TACTICAL BASE> of its defenders. Here the g3-tactical base is defended by the White h2-pawn, which is already attacked by the Black b2-rook and defended only by the White h1-king, a tacitcal situation which screams for <REMOVAL OF THE GUARD> by <ILLUSORY PROTECTION>. So Geller (Black) <REMOVES THE GUARD> of the g3-tactical base with 37 ... b2xh2+!. Position after 37 ... b2xh2+! <remove the guard>

Hence the real reason for the advance of the Black h-pawn is revealed: it did not mindlessly advance to "attack" the White h1-king, it advanced to support a <BISHOP FORK> on g3! Ingenius tactical play by Geller. |
