PROBING FOR WEAKNESSES

In the previous example we learned some very important advice for the endgame.  YOUR KING IS AN ACTIVE
PIECE.  USE IT!  Here White’s king is actively placed but this time Black has also placed his king near the center of
the board.  How can White make progress?  The answer is to probe Black’s position and try to create weaknesses.
White now starts an advance on the Q-side where he has the advantage because of his well placed king.

1 a2-a4 g7-g6
2 a4-a5 h7-h6?

A mistake. Black has completely overlooked White’s idea.

3 a5-a6!!

A fine move. No matter how Black responds, the black pawns on the queen’s side will be forced to weaken their
formation, allowing the white king to decimate them.

3 ... b7xa6

White was threatening simply 4 a6xb7, followed by 5 b7-b8, promoting to a queen. Black’s only alternative was
equally unpalatable: 3 ... b7-b6+ 4 Kc5-c6, followed by Kc6xc7, Kc7-b7, Kb7xa7 and the white a-pawn will then
promote in a few moves.

4 Kc5-c6

White’s king will pick up the c7 pawn, then it will capture the pawns on the a-file, and finally White will advance his
b- and c-pawns to promotion.
