Women's WCh. G6: Hou has two-point lead

by Albert Silver
3/9/2016 – The game started with Muzychuk on the white side of a Giuoco Piano, in which she seemed to have the clear upperhand, and her fans rubbed their hands in the hopes of an equalizing result. Things got complicated and then downright ugly as her knight found itself stranded on the rim, and Hou Yifan flipped the tables for a big win. Report with GM annotations.

It was about as dramatic a game as could be, and tragic… for Ukrainians and Mariya Muzychuk’s fans. It was generally agreed that the time for solid play and wait-and-see chess was past, and if the title holder wished to defend her crown, she would need to take far more energetic measures than she had until now. She was behind the score by a point, and the Chinese challenger did not seem as if she were about to ease up.

The opening choice was a repeat of game one, the Giuoco Piano AKA Italian game, but this time the Ukrainian quickly eschewed the cautious 7.h3 for the sharper 7.Bg5. The choice soon paid off as she built a significant advantage just begging to unleash hell on her opponent. The opportunity arose when she reached this position:

White has built an excellent position, and the time has come to take
advantage of it. White to play and increase her advantage.

Unfortunately she missed the window of opportunity, and as so often happens in such cases, she began to waffle on how to proceed. Five moves later, at a loss on how to progress, she began to go seriously astray, first by removing her strongest piece, the bishop on c4, from its attacking outpost, and then with a king move that just wasted a tempo. Her knight that had seemed a piece to cause trouble, was now a castaway on the island square of h5, with no hope of rescue.

When the tide had turned decisively, Hou Yifan did not waste time as she found and executed the winning blow.

Things have gone all wrong for White, and now Black has the means to
end White's resistance. White to play and win. Solutions in the game notes.
