Test Position: Mamedyarov-Wang Hao (32.g4!!)

Post by Albert Silver »

Mamedyarov played a brilliant game today, beating his rival and taking sole lead. He outplayed his opponent in a simplified middlegame, and punctuated it with this shot:

[D]6k1/2R3p1/p4r1p/1p2rp2/1Pb4P/P7/3R1PPK/1B6 w - - 0 32

32.g4!! Be6 33.g5!
