Jan-27-04  rafaelluiz: Marvelous game. could someone give analisys?
Jan-28-04  Orcinus: <rafaelluiz> I'm not ideal but I'll give it a go. I will deal in strategic principles, leave alone calculations. When I'm against playing that is closed and perhaps defensive and am in an aggressive mood -which is typical- I will often wait for the other side to castle, or where I think he will castle. Then, I will OC (opposite castling) or not castle - a different story. OC activates closed positions especially the pawns. Notice Nezh did not wait for black to castle but weaken the kingside to where 0-0 is doubtful. OC opens the door for counterplay and files can be open with great costs. What's true for files is true for diagnols. Indeed bishops are skillful in doing both offense and defense at once. Note 22 Rxf5 creates an Iso on c6 and how he exploits it.
Aug-01-19  Bobo2002: Maestro rafaelluiz: Yo recojo el guante, de su pedido de análisis. El principio del fin de Mikenas, comienza con la natural, (luego no es natural) jugada 20 b5 del blanco. Que sólamente intenta abrir líneas sobre el recién efectuado enroque largo. Se ha planteado un juego con enroques heterogeneos. 20...Cc5?, bien, con este decisivo error, del negro, comienza un problema táctico de difícil solución. Ahora, el negro amenaza entre otras cosas, 21 ...Axd3 para ganar la calidad. Pero, al mismo tiempo habilitan la jugada "b6" del blanco, lo que ganaría material. Bien, veamos como debió jugar el negro, para proseguir con un mejor juego, que en la partida. A partir de +0.19, (muy pequeña ventaja blanca)20...h4.21 bxc6,bxc6.22 gxh4,Ac5.23 Cf3,dxc4.24 dxc4,Cb8.25 Ae3,Ad3.26 Axc5,Dxc5.27 Df2,Dxf2.28 Txf2,Axc4. Y con +0.67, las negras tendrían un partida jugable, pero no con los problemas que tuvieron en la realidad. Me llama la atención, el error táctico de Mikenas, él no era de cometer ese tipo de errores groseros, quizás haya tenido problemas con el reloj. Pero tambíen, frente a él, estaba nadie menos que Netzhmedinov.
Aug-01-19  Bobo2002: Ahora veamos, el final de partida: El análisis del abandono. Con la jugada 40 Dh8+, obviamente pierden en todas, pero veamos cada una de las cuatro respuestas, como se remata la partida.Las negras tienen 40 ...Cf8, 40...Rc7,40...Rd7, y 40...Re7. 40...Cf8:Esta es la variante en que se pierde mas rapidamente, veamos: 41 Df6+, que a su vez, las negras tienen dos respuestas, 41 ...Rc7, 41 Rd7.

Aug-01-19  Bobo2002: Segunda Variante,40...Rc7.
