Vet­eran Gata Kam­sky suc­cess­fully de­fended his ti­tle at this year’s US Cham­pi­onship in St. Louis by de­feat­ing Varuzhan Ako­bian in the rapid play­off. This is Kam­sky’s fifth US ti­tle, which he won for the first time in 1991.

In the Women’s event, Irina Krush re­tained her ti­tle af­ter some tense mo­ments against Tatev Abra­hamyan in the rapid play-off. This is Krush’s sixth ti­tle.

Kam­sky prefers un­charted wa­ters and orig­i­nal po­si­tions to ex­ten­sive open­ing prepa­ra­tion. In to­day’s game against Sergey Eren­burg from Round 4, Kam­sky came up with the rarely­played 2. Bg5, leading to the strate­gic open­ing bat­tle and a small edge for white.

Even though black has for­ti­fied his po­si­tion solidly, the rapid march of the b-pawn iso­lated and weak­ened the c-pawn, mak­ing it a nat­u­ral tar­get for an at­tack.

Un­der pres­sure, black com­mit­ted an er­ror with 32... Qe7 and was forced to re­sign two moves later. Gata Kam­sky v Sergey Eren­burg in US in 2014: d4 d5 2.Bg5 h6 3.Bh4 c6 4.Nf3 Qb6 5.b3 Bf5 6.e3 e6 7.Bd3 Bxd3 8.Qxd3 Ne7!? 9.c4 Nf5 10.Bg3 Nd7 11.Nbd2 Nxg3 12.hxg3 g6?! 13.e4 dxe4 14.Nxe4 O-O-O 15.O-O e5 16.c5!
