The f7 point is very vulnerable and White  is ready to attack it. 19... c6b8 A very sad move. 20. g2g4 The right plan is kingside expansion. One pawn coming up to the g6 square will completely ruin Black's position. 20... h7h6 The Polish  GM did not like this, as he thought that the light squares around the  opponent's king were getting weak. 21. h2h4  21... g7g6  22. g4g5  22... h6g5
