(1) Perelshteyn,Eugene - Rogers,Ian [A52]
FCO, Round 4, 03.12.2011

Tournament co-winner GM Eugene Perelshteyn suffered his only defeat at the hands of visiting Australian GM Ian Rogers. On first glance, the game appears ironic, as Eugene was lecturing after the tournament on Opening Preparation, and lost to the erratic Budapest Gambit. Upon closer examination, though, we see that Eugene navigated the opening masterfully and pragmatically, securing a significant advantage, before blundering to his doom.

1.d4 Nf6 2.c4 e5 3.dxe5 Ng4 4.Nf3
As Eugene remarked, a pragmatic decision, avoiding the main theoretical byways when confronting a surprise opening in a speed game.

4...Bc5 5.e3 Nc6 6.b3 0-0 7.Bb2 Re8 8.h3 Ngxe5 9.Nbd2
Eugene has a solid position with nothing to complain of. A nice way to handle things given the surprise value of black's opening choice.

9...d6 10.Be2 Qf6 11.Nxe5 Nxe5 12.Qc2 Bf5 13.Qc3 Qg6 14.g4 Bd3 15.b4!
And white wins a piece. Black has compensation, however, in the form of active piece play.

15...Bb6 16.c5 dxc5 17.bxc5 Bxc5 18.Qxc5 Bxe2 19.Kxe2
The computer pinpoints this as to blame for White's woes, suggesting Bxe5 instead.

19...Qd3+ 20.Ke1 Rad8 21.Bxe5?!
[21.Bd4 After the game I suggested this move to Eugene, who doubted White's position. As it turns out, he was right, as Rybka whips out the following advantageous variation for black. 21...Nc6 22.Bc3 Rd5 23.Qc4 Qxc4 24.Nxc4 Rc5 ]

21...Qxd2+ 22.Kf1 Rd5 23.Qxc7 Rdxe5 24.Qxb7
Eugene assessed this position as drawish; black is down a pawn, but has compensation.

24...h5 25.Qf3 R5e6 26.gxh5
and identified this as overly greedy, suggesting g5 instead, preventing Rf6.

26...Rf6 27.Qg3?
[27.Qe2 Eugene rejected this as too drawish, having missed Black's next, but commendation must be made for Eugene's fighting spirit in this event!! 27...Qxe3 28.Qxe3 Rxe3= ]

27...Rxe3 28.Qb8+ Kh7 29.Qb1+ Kh6 30.Rh2 Rxh3!
A deadly deflection. 0-1
