Nxd3 { [#]Looking at this position it is hard to foresee that both sides will get passed pawns just ten moves later.

But the very next move induces some structural changes.} bxc4 11. bxc4 dxc4 12. Ne5 Nbd7 {By giving up the tension, Black hopes to play .. . c6-c5 in time, which would lead to a drawish simplification. Abstractly, I find this approach a bit inconsequent.

His pawn is more advanced and, for once, his queen is a perfect blocking piece! Placed on a light square it cannot be attacked easily, safely defending the d5- and (not least) a2-pawns and keeping an eye on the a6-pawn. We could say that, far from creating any threats, the black pawn is the safest "umbrella" for the white queen!

Rd1 Qg6 {Black keeps the d5-pawn under control, defends his queenside pawns rather safely. Moreover, the queen is prepared to secure the kingside, too. Black's next moves would be ...Bf8 and .. .h7-h5, after which he will stick to half waiting moves. White's position would remain more active, but without obvious ways to make progress.}) 23. g3 Qa5 {This is the consequent follow-up of the previous move. After having blocked the pawn by simple means, Black is free to activate his queen. The last move prevents Bd2 (although this is relative, as we will see) and prepares questioning the white queen's stability with ...Rab8 followed by either ...Rb4 or ...Qb5 shortly after. But on the other hand, taking the queen far from the kingside is a risky and, what's worse, ireversible, decision.} 24. Rd1 (24. Bb2 $6 Qb4 {would solve most of Black's problems.}) 24... Rab8 25.
