Black spent considerable time in response to the surprise on move 10, failed to find the most critical reply, and ultimately ends up down a pawn with a structural problem on the kingside and without a pair of bishops to claim as compensation. Additionally, White's isolated d-pawn is not even very weak, especially now that Dominguez has prevented Black from blockading it on the d5-square. } { [%clk 0:52:24] } 19...

Rb2 { The critical line. } { [%clk 0:07:49] } 24. Rf1 { Can't Black claim "activity" as compensation for the pawns? Well, three passed pawns is a lot of passed pawns. Additionally, without minor pieces, it will be difficult to "break through." Instead, Black's rooks will eventually have to retreat to cover the pawns, so White's "passive" f1-rook is only a temporary, rather than long-term, liability. } { [%clk 0:38:04] } 24...
