Qb3 b5 {It is becoming evident that Black will use his Q4 square as a pivot to gain space on the Q side. If White can restrain Black's attack on the QB file by trading off pieces, Black will march his K to Q4 for an endgame advantage. White tries a K-side attack, which is doomed to failure due to Black's ability to travel through the center with his pawns.} 21. Bh3 Kh8 22. Qd3 Nb6 23. Ng6+ fxg6 24. Rxe6 Qd7 25.
