Mar-23-06  zev22407: White sacs a knight on f5 to catch black's king in the center.Black was able to castle but no shelter for the king there!
Feb-26-11  wordfunph: terrific 13.Nf5!

GM Kavalek's remark on this game, "...my king in the center, surrounded by dancing white pieces. I lost my king, my game, and my good mood."

Dec-27-12  jerseybob: Up to 10..h6 exactly as in Stein-Najdorf Mar Del Plata 1965. Stein played 11.Bxf6 and lost. Calvo varies with 11.Bh4 and now, with the queen on e2 instead of f3, the Brownean 11..g5 is dubious.
Dec-27-12  jerseybob: And furthermore: Kavalek may have been planning the standard Brownean Ne5 on his next move, but 13.Nf5! is a shocker. 11..Nb6 might be worth a look. If 12.e5,de 13.fe,Nfd5 aiming for Bd7 and 000
