Commentary: 2015 U.S. Championship, Round 4 (Wang-Foisor)

By coincidence, this game from the fourth round of the 2015 U.S. Championship (women's section), like the previous commentary game from round 2, features an Exchange Slav.  Also like the previous game, it is anything but boring.  Black follows a symmetry-breaking sideline starting on move 6 and introduces some positional imbalances with the pawn structure and central control.  White fails to challenge Black effectively, missing an interesting tactical idea involving a temporary sacrifice followed by a pawn fork, then Black's space advantage eventually makes itself felt.  It is instructive to see Sabrina Foisor as Black effectively use her advantage to increase her positional edge before winning material, as well as calmly sort her pieces in the final phase before making a decisive penetration of her opponent's territory.
