Este 75º campeonato disputou-se em Dezembro em Porto Alegre - a capital dos gauchos.
Com 5 GMs e 4 IMs num round robin a 12 jogadores, este torneio atingiu categoria 9 e assim, foi seguramente o mais forte já disputado no Brasil !
O jogo decisivo...

75th Brazilian Ch, Porto Alegre, (11.2), 16.12.2008
1.e4 c5 2.Nf3 e6 3.Nc3 a6 4.d4 cd4 5.Nd4 d6 6.Be2 Nf6 7.0-0 Be7 8.f4 0-0 9.a4 Qc7 10.Be3 b6 11.Bf3 Bb7 12.g4 Nc6 13.g5 Nd4 14.Qd4 Nd7 15.Qd2 Rfe8 16.Bg2 Bf8 17.Rf3 d5. Vescovi needs a full point and take some risks. 17...b5 was interesting but after 18.ab5 ab5 19.Ra8 Ra8 20.Nb5 Qc4 21.Nc3 Be4 22.b3 Ra1 23.Rf1 Rf1 24.Bf1 Qb4 Black could hardly play for a win. 18.ed5 Rad8 19.Rh3 Nc5 20.Qf2. Even needing just a draw, Diamant plays aggressively. Another try is 20.b4 Nd7 21.Qd3 g6 22.d6!? 20...ed5 21.Qh4 h6 22.gh6
The critical moment. How must Black defend? 22...d4! 23.hg7 Bg7 24.Bb7 Nb7. Better 24...Qb7 25.f5! Qc6 (25...Ne4 26.Qh7 Kf8 27.Bh6 Bh6 28.Rh6 dc3 29.Qh8 Ke7 30.Re6!+/-; 25...de3? 26.f6+-) 26.Qh7 Kf8 27.Rg3 Re3 28.Qg7 Ke8 29.Re3 de3 unclear] 25.Qh7 Kf8 26.Rg3 f6 27.Ne4 Re4 28.Qe4 de3 29.Re3 Nd6 30.Qb4 a5 31.Qc3 Nc4. After a well calculated defense, Black got the better game. 32.Rd3 Qc5 33.Kh1 Qc6 34.Kg1 Qc5 35.Kh1 Rd3 36.Qd3 Qc6 37.Kg1 Nb2-/+ 38.Qa3 Qc5 39.Qc5 bc5 40.f5 Bh6. Black has a clear advantage as the rook is passive. Anyway, the endgame is far from simple. 41.Ra3 c4 42.Kf2 Ke7 43.Rg3 Kd6 44.Rg6 Bg5 45.Kg3 Ke5 46.Kg4 Bd2 47.Rg8 Nd1. Time pressure. 47...Na4 48.Rd8 Be3 49.Re8 Kd4 50.Re6 Nc5 51.Rf6 a4 gives Black better winning possibilities. 48.Rd8 Ne3 49.Kf3
49...c3? 49...Nd5 was necessary: 50.h4 c3 51.Re8 Kf5 52.Ra8 Ne3 53.Ra5 Ke6 keeps Black with clear advantage in a complex endgame. Now White is winning: 50.Re8 Kf5 51.Re3 Be3. Draw agreed. White is winning, but half a point is enough for Diamant. Now 51...Be3 52.Ke3 Kg4 (52...Ke5 53.Kd3 Kf4 54.Kc3 Ke3 55.h4+-) 53.Ke4 f5 54.Ke3 f4 55.Ke4 f3 56.Ke3 is zugzwang. 1/2-1/2
