Depois de conversar com os amigos Reinaldo (dilucia) e Roberto (robelix), estamos abrindo um tópico para análises de partidas. Pensei, a princípio, em usar como idioma somente o português, pois quando escrevo em inglês sinto-me tão confortável quanto os hóspedes daquele hotel lá em Guantánamo. Mas tanto o Roberto quanto o Reinaldo são ases da língua de William Shakespeare, John Milton e Michael Jackson. Portanto, o melhor é abrir para qualquer língua, e um dos amigos que faça a tradução deste prefácio, caso contrário estas considerações não ficam parecendo coisa de brasileiro...
Para começar as análises, a minha segunda partida realmente difícil aqui no QA (a primeira foi contra "franliro"). Abaixo, para comparação, outra partida contra o mesmo oponente cerca de 6 meses depois. Todas as duas partidas foram jogadas em dois ou três dias.
1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. Bg5 e6 7. f4 Nbd7 8. Bd3?! Apesar desta linha ser jogada inclusive em nível magistral, minha opinião é que se trata de um erro posicional: o bispo branco corta precocemente a trajetória ( e, portanto, o poder de fogo ) da própria dama, impedindo que ela atue no centro, o que é sempre um problema para as negras na Siciliana. E, ainda por cima, deixa o cavalo solto, sem proteção, exposto ao ataque da dama negra em 6. Nas partidas que examinei do meu oponente, em todas as Sicilianas ele havia optado por essa linha, embora em posições ligeiramente diferentes. Portanto, eu a estava esperando. Porém, há aqui um agravante: essa posição é conhecida desde o início da década de 60 - e a resposta, devida a Mikhail Thal, na época campeão do mundo, também é conhecida. 8... Qb6 Shianovski-Thal, Baku, 1961, 1. Outras alternativas são: 8... h6 e 8... Be7. 9. Nb3 Qe3+ Além da partida acima mencionada, é digna de nota, para esta manobra tática, só possível devido ao erro posicional das brancas na oitava jogada, a partida Shaked-Leitão, Duisburg, 1992, 0-1, jogada 31 anos depois da primeira. V., também, Tukmakov-Ankerst, Lvov, 1962. 10. Qe2 Qxe2+ 11. Kxe2?! A tomada com o bispo ( tal como fizeram Shianovski e Tukmakov ) , ou mesmo com o cavalo ( como fez Shaked ) , eram melhores. 11... Be7 12. a4 h6 Talvez nessa posição 12... b6 fosse melhor. 13. Bh4?! Era melhor 13. Bxf6, mas, provavelmente, meu oponente não gostou da idéia de ter a diagonal dominada pelo bispo negro depois de 13... Bxf6. 13... b6 14. Bf2 Bb7 15. h3 Rc8 Existia a alternativa 15... Nh5. 16. Nd2! Meu oponente previu, corretamente, um sacrifício de qualidade com ganho do peão e4 e domínio do centro pelas negras, e decidiu aqui por uma jogada profilática. 16... Nh5 17. g3 g5 18. fxg5? O melhor era 18. 5. hxg5 19. Rag1 Bf6 20. Nc4 Ke7 Aqui, existia a combinação 20... Rc4! 21. Bxc4 Bxc3 22. bxc3 Nhf6 23. Bd3 Bxe4 24. Rh2 ( 24. Bxe4 Nxe4 ) 24... Bg4, mas a tática jamais foi o meu terreno predileto. 21. Kd2?? Um erro que perde imediatamente a partida. Eu estava esperando 21. Nxb6. Mas, com a jogada do texto, o resto é o que se chama uma tarefa técnica. 21... Bxc3+ 22. bxc3 Nhf6 23. Nxb6 Nxb6 24. Bxb6 Bxe4 25. Rh2 Ng4 26. Re2 Bxd3 27. cxd3 Rxh3 28. c4 Ne5 29. Kc3 Nf3 30. Rgg2 30... g4 31. Rb2 d5 32. Ba7 f5 33. Rb7+ Kf6 34. Be3 34... e5 35. Rb6+ Kf7 36. Kb3? dxc4+ 37. dxc4 f4 38. Rb7+ Ke6 39. Ba7 Rxg3 40. Rxg3 fxg3 0-1
O curioso na partida abaixo é que ela segue exatamente a anterior até a 13ª jogada.
1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. Bg5 e6 7. f4 Nbd7 8. Bd3 Qb6 9. Nb3 Qe3+ 10. Qe2 Qxe2+ 11. Kxe2 Be7 12. a4 h6 13. Bxf6 Meu oponente não comete o erro da partida passada ( 13. Bh4 ) . 13... Bxf6! Saindo da trilha mais rotineira ( 13... Nxf6 ) e disputando o centro de forma mais aguda. 14. a5 Bxc3 Eliminando a principal peça branca na disputa pelo centro e, ao mesmo tempo, obrigando as brancas a dobrar peões na coluna "c", a tradicional coluna de ataque das negras na Siciliana. Apesar do mau gosto literário, é correta a frase de Fischer: "os peões dobrados caem como dentes de velhas". A alternativa 14... Nb8, com o plano de levar o cavalo para c6, me pareceu demasiadamente lenta. 15. bxc3 e5 Seria mais comum 15... Nf6, mas eu queria algo que, como disse Nunn, "colocasse o oponenete para pensar". 16. g3?! Uma surpresa. Havia previsto 16. fxe5, 16. Rhf1 ou 16. f5. Mas a jogada do texto é demasiado passiva para a posição. 16... Ke7 Melhor do que 16... 0-0, pois economiza um tempo: as negras usam o rei para proteger o peão de d6 - a sua maior debilidade - ao mesmo tempo em que desobstruem a última fileira para a torre da coluna "h". 17. Ke3 Nf6 Levando mais uma peça para disputar o centro e, ao mesmo tempo, mirando na casa 4. 18. h3?! Impede o xeque em g4, mas cria mais uma debilidade. Provavelmente era melhor tentar minimizar um pouco as debilidades no flanco da dama - o flanco de ataque das negras - com 18. Rab1, ou, 18. c4, ou, imediatamente, 18. Nd2. 18... Bd7 19. Nd2?! Agora, depois de 18... Bd7, esta jogada não é a melhor. As brancas poderiam igualar com: 19. fxe5, seguindo-se: 19... dxe5 20. Nc5 6. Rhc8 20. Nc4 Rc5! A exclamação não é por conta do valor intrínseco da jogada, mas porque ela foi, para mim, o lance mais difícil de todo o jogo. Era uma tentação 20... exf4+, mas depois de 21. gxf4 d5 22. Nb6 dxe4 23. Nxa8 Rxa8 24. Be2 24... Nd5+ ( 24... Ne8 25. Rhd1 ) 25. Kxe4 Nxc3+ 26. Ke3 Nxe2 27. Kxe2 a posição das negras está longe de ser invejável. 21. Rab1?? Esta jogada põe o jogo a perder. Eu estava esperando 21. Nb6 e tinha preparado a resposta 21... Re8. Rac8 22. Rb4 R8c7 Alguém, talvez Steinitz, disse que "quando estiver em vantagem, preocupe-se primeiro com a defesa". 23. Rhb1 exf4+ 24. gxf4 d5 25. e5? dxc4 26. exf6+ Kxf6 27. Bf1 27... Bc6 28. Rxc4 Re7+ 29. Kd2 Rxa5 30. Rd4 g6 31. Rb6 Kg7 32. Be2 32... Ra1 33. Bd1 a5 34. h4 a4 0-1

On behalf of Mr Carlos Csparrow, translating the first game of the two:
After talking to some friends, Reinaldo (dilucia) and Roberto (robelix), we are opening a space for game analyses. I thought at first to write only in Portuguese because when I write in English I feel as comfortable as the "guests" at Guatanamo hotel. But Roberto and Reinaldo are experts at the language of Shakespeare, John Milton and Michael Jackson so English will be used as well.
To start my analyses I'll talk about one of my most difficult games here in Queenalice. Following I'll show, as a way of comparison, another game against the same opponent, 6 months afterwards. Both games were played in two or three days.
Jim Morrison x Csparrow 0-1
1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. Bg5 e6 7. f4 Nbd7 8. Bd3?! Even though this line is played at master level, in my opinion it is a positional mistake: the Bishop gets in the way of the Queen, and as a result shortens her fire range, blocking her influence in the center, which is always a problem for Black in the Sicilian. To make matters worse it leaves the Knight in ( d4 ) hanging, without any protection, and exposed to atack by the Black Queen if she goes to ( b6 ) . Studying Jim Morrison's games I noticed that he always played this move in the Sicilian, although in positions slightly different. So I kind of expected the move. There is also something very important to say about the position: it has been known since the 60's, and the reply, credited to Mikhail Tal, who was the chess reigning king, is well known since then... 8... Qb6 Shianovski-Thal, Baku, 1961 ( Others are 8... h6 e 8... Be7 ) 9. Nb3 Qe3+ It is also worth considering the game Shaked-Leitão, Duisburg, 1992, 0-1, played 31 years after Tal's game, where the tactical manoeuvre was only made possible because of the positional mistake in move 8. See also Tukmakov-Ankerst, Lvov, 1962. 10. Qe2 Qxe2+ 11. Kxe2?! Taking with the Bishop as Shianovski and Tukmakov did in the past, or even with the Knight as Shaked did, would be better 11... Be7 12. a4 h6 ( Maybe 12... b6 would be better ) 13. Bh4?! ( 13. Bxf6 looks better ) Probably my opponent didn't enjoy the idea of having the diagonal dominated by the Black Bishop. 13... b6 14. Bf2 Bb7 15. h3 Rc8 ( 15... Nh5 was worth considering ) 16. Nd2! Morrisson correctly predicted a quality exchange at ( c3 ) and loss of the pawn in ( e4 ) and center control by Black, so he decided to make a prophylactic move 16... Nh5 17. g3 g5 18. fxg5? ( Best was 18. f5 ) 18... hxg5 19. Rag1 Bf6 20. Nc4 Ke7 Here there was a combination ( 20... Rc4! 21. Bxc4 Bxc3 22. bxc3 Nhf6 23. Bd3 Bxe4 24. Rh2 Ng4 ) but tactics has never been my favorite subject 21. Kd2?? A blunder that loses the game. I was expecting ( 21. Nxb6 ) but with the text move what remains is what many writers call a matter of technique 21... Bxc3+ 22. bxc3 Nhf6 23. Nxb6 Nxb6 24. Bxb6 Bxe4 25. Rh2 Ng4 26. Re2 Bxd3 27. cxd3 Rxh3 28. c4 Ne5 29. Kc3 Nf3 30. Rgg2 g4 31. Rb2 d5 32. Ba7 f5 33. Rb7+ Kf6 34. Be3 e5 35. Rb6+ Kf7 36. Kb3 dxc4+ 37. dxc4 f4 38. Rb7+ Ke6 39. Ba7 Rxg3 40. Rxg3 fxg3 0-1

I'll make my contribution to this forum showing a very short game played recently, Robelix x Reusking, at the Brasil-Spain Match which is still in progress here in the site. The game is interesting to show how a quiet and worn out variation can go wrong in a matter of a few moves. It also shows how important is the use of books and databases in correspondence chess as a way to research and improve someone's own game.
1. d4 d5 2. c4 e6 3. Nc3 Nf6 4. Bg5 Be7 5. e3 O-O 6. Nf3 Nbd7 7. Rc1 c6 8. Bd3 dxc4 9. Bxc4 Nd5 10. Bxe7 Qxe7 11. O-O Nxc3 12. Rxc3 I was trying to change my repertoire ( I've played mostly Colle systems with d4 and e3 ) , so I underwent in some well known variation of the Queens Gambit Declined, just to play safe and to avoid sailing in dangerous waters. The problem with this approach is that you start playing ultra-analysed lines that usually lead to boring draws. My opponent didn't take risks too and so far was playing a solid defense which is the main line in the Queen's Gambit. The same moves have been played since the nineteenth century by people like Capablanca, Euwe and Alekhine 12... e5 The first move to wake me up for the game. I had to start to make decisions for the rest of the game: exchanging the pawns and the Knights in the center both of the options I didn't like at all 13. Qc2 I decided to develop the Queen and wait. ( Others would be: 13. dxe5 Nxe5 14. Nxe5 Qxe5 15. Qb3 ) Or something that would lead to the ending game ( 13. Nxe5 Nxe5 14. dxe5 Qxe5 15. f4 Qe4 16. Qe2 Bf5 17. Bd3 Qd5 18. e4 Qd4+ 19. Qf2 Qxf2+ 20. Kxf2 Bd7 ) 20... exd4 Or he could have chosen ( 13... e4 14. Nd2 Nf6 15. Rc1 Bf5 16. a3 ) 14. exd4 Nf6 This was the first weak move. An apparently innocent move but that gives White some iniciative. Better would be ( 14... Nb6 15. Re3 Qd8 16. Bb3 Nd5 17. Bxd5 Qxd5 18. Re5 Qd6 19. Ng5 Qg6 20. Qxg6 hxg6 21. Re7 f6= ) 15. Re1 Qd6 16. Ng5 This was played by Alekhine himself and contains a lot of poison. It leaves a pawn hanging in the center and start threatining ( f7 ) 16... h6 ?? What amazes me is that this very move, which is a blunder, has been played for over 6 decades now, at master level included. It leads to a quick loss of a piece and the game. ( 16... Qxd4 17. Rf3 ) Threatening to win the Knight or mate with the Queen. ( 17... g6 18. Re7 Bg4 19. Rd3 Qf4 20. Nxf7± ) The best here would probably be ( 16... Bg4 ) which I couldn't see any advantage for me, until I analysed it after the game, with Fritz. ( 17. Nxf7 Rxf7 18. Bxf7+ Kxf7 19. Qb3+ Kf8 20. Qxb7 20... Rb8 21. Qxa7 ) 17. Nxf7 Rxf7 18. Qg6 Qf8 19. Rf3 The key move in the combination, that could have been avoided if the Bishop had developed to defend that square... 19... Bg4 And here comes the prelate as the suffix says: late...But it is a original way of complicating things for the attack. Others in the same mouse trap tried different things. ( 19... Nd5 20. Rxf7 Qxf7 21. Re8+ Qf8 And the Black Queen is gone... ) 20. Rxf6 Bh5 Playing against hope that White would falter and allow Black some counterplay, even with the game already lost 21. Qxh5 ( 21. Qg3 Qb4 22. Bxf7+ Bxf7 23. Rf1 Qxd4 24. Rxh6 Qxb2 25. Rh4 Bxa2 26. Qg6 Qf6 27. Qh7+ Kf7 28. g3 Bd5 29. Re1 Qf3 30. Rf4+ Qxf4 31. gxf4 By Professor Fritz... ) 31... gxf6 22. Qg6+ As always when I analyse something I think I did well, Fritz comes and spoils it with some disdain, showing a quicker and smarter way of playing. ( 22. Re3 Kh8 23. Bxf7 Rd8 24. Rg3 f5 25. Qxf5 Rd6 26. Qe5+ Kh7 27. Rg8 ) 27... Qg7 23. Bxf7+ Kf8 24. Qxg7+ And Black resigned 1-0 My plan, not as good as Fritz's, was to go a Rook and Bishop X Rook ending. Not very hard to acomplish but always with space for improvement. ( 24... Kxg7 25. Bh5 Defending the back rank and keeping the King inactive 25... Rd8 26. Re7+ Kg8 27. Rxb7 And Black pawns get lost in space... 27... Rxd4 28. Rxa7 Rd2 29. b3 Kf8 30. g4 Re2 31. Rc7 Rxa2 32. Rxc6 )

This is the second game annotated by Csparrow, now tranlated to the language of Bobby Fischer! Jim Morrison X Csparrow AUTO-ELITE-26 http://www.queenalice.com/game.php?id=74937 "Curiously the second game we played had the same moves until move 13. " 1. e4 c5 2. Nf3 d6 3. d4 cxd4 4. Nxd4 Nf6 5. Nc3 a6 6. Bg5 e6 7. f4 Nbd7 8. Bd3 Qb6 9. Nb3 Qe3+ 10. Qe2 Qxe2+ 11. Kxe2 Be7 12. a4 h6 13. Bxf6 Here my opponent doesn't make the same mistake of the previous game ( 13. Bh4 ) 13... Bxf6! Getting off the beaten track ( 13... Nxf6 ) and challenging the center in a sharper way 14. a5 Bxc3 Eliminating the the principal White piece in the fight for the center and, at the same time, forcing White to double pawns in the C-file, which is the traditional attacking gateway for Black in the Sicilian. As Fischer said "the double pawns fall like an old woman teeth". The alternative ( 14... Nb8 ) , as a plan to take the Knight to ( c6 ) , appeared to me as very slow. 15. bxc3 e5 ( 15... Nf6 ) Would be something more common but I wanted something, as Nunn said, that "gave the opponent some to worry about" 16. g3?! A surprise for me. I had expected ( 16. fxe5, or 16Rhf1, or 16. f5 ) but the text move is too passive for the position. 16... Ke7 Better than ( 16... 0-0 ) which saves one tempo: Black use the King to protect the pawn in ( d6 ) , that is Black's more vulnerable piece, and at the sime time clears the last rank for the rook in the h-file. 17. Ke3 Nf6 Bringing one more piece to help in the center while pointing at ( g4 ) 18. h3?! Prevents the check in ( g4 ) but creates one more weakness. It was probably better to try minimizing the weaknesses on the Queen side, where Black were supposed to atack ( 18. Rab1, or 18. c4, or 18. Nd2 at once ) 18... Bd7 19. Nd2?! Now after ( 18... Bd7 ) , this is not the best option anymore. White should equalize with ( 19. fxe5 dxe5 20. Nc5 ) 20... Rhc8 20. Nc4 Rc5! The exclamation mark is not because the move quality but it was the most difficult for me in the game. ( I had the tempting move 20... exf4 but after 21. gxf4 d5 22. Nb6 dxe4 23. Nxa8 Rxa8 24. Be2 Nd5+ ( 24... Ne8 25. Rhd1 ) 25. Kxe4 Nxc3+ 26. Ke3 Nxe2 27. Kxe2 Black's position would be far for enviable ) 21. Rab1?? This was a losing move for White. I was expecting ( 21. Nb6 and had 21... Re8 ready ) 21... Rac8 22. Rb4 R8c7 Somebody, maybe Steinitz, said that when you have an advantage it's about time to worry about your defense. 23. Rhb1 exf4+ 24. gxf4 d5 25. e5 dxc4 26. exf6+ Kxf6 27. Bf1 Bc6 28. Rxc4 Re7+ 29. Kd2 Rxa5 30. Rd4 g6 31. Rb6 Kg7 32. Be2 Ra1 33. Bd1 a5 34. h4 a4 0-1
