Another BDG from the US Amateur Team East

Lev Zilbermintz had a pretty good outing at the recent US Amateur Team Championships, scoring 5 of 6 with four wins and two draws, and two of the wins were Blackmar-Diemers. Here's the second one.

Note: I've added a link at the end of post to play through the game and download a copy in PGN.

Zilbermintz,Lev (2010) - Wyatt,Jordan R
US Amateur Team-ch East Parsipanny USA (2), 14.02.2009
BDG, Bogoljubov Defense

1.d4 d5 2.e4 dxe4 3.Nc3 Nf6 4.f3 exf3 5.Nxf3 g6 6.Bc4 Bg7 7.0-0 0-0 8.h3

This avoids the most common Black defensive lines with Bg4, and discourages the Bf5 lines. 8...b6 Since Bg4 is precluded, Black looks for another way to trade off the Knight on f3. 9.Qe1 Bb7 10.Qh4 Bxf3 11.Rxf3 Nc6 This Knight begins a strange journey that ends in disaster. 12.Ne2 Re8 13.c3 Na5 14.Bd3 c6 15.Bg5 Nb7 16.Raf1 Nd6 This replaces, perhaps unintentionally, the guard on f7 that Black removed with his 12th move. 17.Bh6 b5 18.g4 Nc4?+- 

So much for holding f7. 19.Bxc4 bxc4 20.Bxg7 Kxg7 21.g5 

21...Nh5?+- [Not the best move, but Black is lost anyway. 21...Rb8 22.Qh6+ Kh8 23.gxf6 exf6 24.Rxf6 Qe7 25.Rxf7 Qe3+ 26.Qxe3 Rxe3 27.R1f2 Rxb2 28.Rxa7 Kg8 29.Nf4+-] 22.Rxf7+ Kh8 23.Ng3 Ng7

24.Qf4?+/- [Missing a forced mate with 24.Qh6 Rg8 25.R1f4 Qd6 (or just about anything else) 26.Qxh7+! Kxh7 27.Rh4#] 24...Rg8 25.Qe5 Qd5 26.Rxe7 Qxe5 27.Rxe5 Rae8 28.Rfe1 Rxe5 29.Rxe5 Rb8 30.Re2 Rf8 31.Kg2 Kg8 32.Rf2 Re8 33.Re2 Rf8 34.b4 Rb8 35.Re5 Rb5+- 36.Rxb5 cxb5 37.Ne4 Nf5 38.Kf3 Kf7 39.Ng3 Nxg3? Black surrenders. 40.Kxg3 a5 41.a3 axb4 42.axb4 Ke7 43.Kf4 Ke6 44.Ke4 Kd6 45.d5 Kd7 46.Ke5 Ke7 47.d6+ Kd7 48.Kd5 Kd8 49.Kc6 Kc8? 50.Kxb5 Kd8 51.Kxc4 1-0.
