NM PEREZ VS SOL CRUZ
















W: NM Roland PEREZ
B: Rolly SOL CRUZ
3rd SOL CRUZ MEMORIAL CUP

1 d4 d5 2 c4 c6 3 Nf3 Nf6 4 Nc3 e6 5 e3 Nbd7 6 Qc2
In opening theory, this Q move is known as the STOLTZ VARIATION which is second in popularity [2,485 games played] to 6 Bd3 [2,963].

6 ... Bd6
This is the standard continuation, played 2,204 times in 2,485 games in the Chessgames.com database. Three World Champions preferred this move; Kasparov, Kramnik and Anand.

7 Bd2
In Karpov-Kasparov World Championship 1984, W played 7 e4, in Karpov-Kamsky World Championship 1996, W continued with 7 Be2, and in Karpov-Anand World Championship 1998, W proceeded with 7 Bd3.

7... e5

The usual reply to the not so popular 7 Bd2 is 7... O-O, 125 times in 139 games, as in Vladimirov-Antoshin in Alekhine Memorial 1963, Leon-Shumiakina in Capablanca Memorial 1991, Belozerov-Goloshchapov in Geller Memorial 1999, Eliseev-Skatchkov in Petrov Memorial 2002, and Arencibia-Perez in Torre Memorial 2006.
