1.e4 e5 2.Nf3 Nc6 3.Bb5 a6 4.Ba4 Nf6 5.0-0 Be7 6.Re1 b5 7.Bb3 0-0 8.c3 d6 9.h3 Nb8 10.d4 Nbd7 11.Nbd2 Bb7 12.Bc2 Re8 13.Nf1 Bf8 14.Ng3 g6 #

In New In Chess Yearbook 66, GM Paul van der Sterren considers this variation completely harmless for Black because of the 'wonderfully unassailable knight on c5' after 15....c5, 16....c4 and an eventual Nc5. [ 15.b3! van der Sterren]

15...c5 16.d5 c4 17.Bg5 h6 18.Be3 Nc5 19.Qd2 h5 20.Bg5 Be7 21.Bh6 Nh7 22.Ra3 Rb8 23.Rea1 Bc8 24.axb5 axb5 25.Be3 Bf6 26.Ne2 Bd7 27.Ra7 Qc8 28.Bxc5 dxc5 29.Qe3 Bd8 30.R7a6 Kg7N
[ In Timman,J-Portisch,L/Bruxelles 1988, the game went 30...Qc7 31.Nc1 Bc8 32.Rc6 Qe7 Instead of taking the offered c5 pawn, Timman chose to sacrifice the exchange with 33.d6?! ( In Informator 45, the assessment given after 33.Qxc5 Qxc5 34.Rxc5 Bd7! 35.d6 f6 was that Black has sufficient compensation for the pawn. But perhaps Hamarat has a different opinion of this ending.) 33...Qd7 34.Qxc5 Bb7 35.Rca6 Bxa6 36.Rxa6 Qb7 37.Ra7 and after 37...Bb6! his game went downhill. 38.Rxb7 Bxc5 39.d7 Red8 40.Rxb8 Rxb8 41.Nxe5 Rd8 42.b3 f6 43.Nf3 Rxd7-+ 0-1, Timman,J-Portisch,L/Bruxelles 1988/Inf 45 (52)]

31.Ng3 Bb6 32.Ng5!
#It seems strange to exchange the well placed Nf3 for its h7 counterpart but Hamarat wants to trade off the sole defender of the Black Kingside as well as to accelerate the f2-f4 push.

32...Qd8 33.Nxh7 Kxh7 34.f4
Textbook stuff. Hamarat follows the maxim that upon securing an advantage (complete control of the a-file), one has to create a second weakness in order to play for a win.

34...Bc8 35.R6a2 Qd6 36.f5
White has a bind on both the Kingside and Queenside.

36...h4 37.Nf1 Kg7 38.Nh2 Bd8
[ 38...gxf5? 39.exf5 Qxd5?? 40.Qg5+ Kf8 41.f6+- ]

39.Ng4 Rh8 40.Ra7 Bc7 41.Rf1 f6 42.fxg6 Bxg4 43.hxg4 Ra8 44.Rb7 Rhb8
# White to play and win brilliantly! Of course Hamarat could just play Rxb8 first before carrying on with his Kingside offensive but...

Giving up the Rb7 for a glorious finish!

45...Rxb7 46.gxf6+ Kxg6 47.Qh3
and Black has to give up his queen to starve off mate.

47...Qxf6 48.Rxf6+ Kxf6 49.Qxh4+ 1-0
