1.e4 e6 2.d4 d5 3.Nc3 Nf6 4.e5 Nfd7 5.f4 c5 6.Nf3 Nc6 7.Be3 cxd4 8.Nxd4 Qb6 9.Qd2 Qxb2 10.Rb1 Qa3 11.Bd3 Bb4 12.Rb3 Qa5 13.0-0 Nxd4 14.Bxd4 Bc5 15.Bxc5 Qxc5+ 16.Kh1 0-0 17.Qe2 Qe7
This move looks natural and perfectly sound. Would you suspect that there is a little surprise waiting for Black?

18.Bxh7+! Kxh7 19.Qh5+ Kg8 20.Nb5 f5 21.Rh3 Nf6
Black is not had a chance to enjoy his extra piece, which he must now return, because White is threatening [21...-- 22.Qh7+ Kf7 23.Nd6+ ]

22.exf6 Qxf6 23.Nc7!
Very deep. The knight is on its way to pick up the pawn on g7 and tear open the black king's defences.

23...Rb8 24.Ne8 Qh6 25.Qf3 Qg6 26.Nxg7 Kf7
The knight is untouchable, since KxN or QxN both fail to Rc3.

27.Rg3 Qh6 28.Qc3 Bd7 29.Qc7 Rfd8
All the spectators on the Playchess server agreed at this point that 30.Re1 was coming their powerful engines told them that. But ZackS has a more convincing plan.

30.Rg5! Rbc8 31.Qxb7 Rc4
Threatens 32...Rxf4 33.Rxf4 Qxg5.

32.Rg1!
A very unsual way to defend the pawn on f4 -- by removing the defending piece!

32...Ke7
[After 32...Rxf4 comes 33.Nxe6 Qxe6 (33...Kxe6 34.Qa6+! ) 34.Qc7! forking the two rooks!]

33.Re1
Now the move the spectators were clamouring for is much stronger.

33...Kf8 34.Nxf5 Qf6 35.Qa6
and Black can do nothing against the threat Qd6+. Rentner2 resigned. 1-0
