Clearly, the pawn on c5 is under attack, but Black has more than one way to defend it.} Qb6 (7... c4 8.

Be3 $1 {Almost out of the blue, Black's position is uncomfortable. His queen is not the best placed, the bishops are powerful and g7 is shut down. } Qb4 21. Rfc1 Na5 22. Bd2 Qb6 23. Bxa5 Qxa5 24.

White has to somehow solidify, consolidate his position and then use his passed f-pawn to cause real problems.} 28. Qd4 (28.
