Nh4 Nc6 { Here black ignores the threat made by white, as they can recapture with the e pawn, now that we can castle to the queenside we can allow a weekend f pawn. } 9. a3 Bxc3 { Here white tries to threaten the bishop, however in this cases it's a bishop for a knight and vice versa. } 10. Bxc3 Bg4!! { Now, whilst this is a queen trade, it is in blacks favour, as it either doesn't allow the king to castle at all, or it doesn't allow white to castle to the queenside. From here on out the opining ends and the middlegame begins, however here are some quick ideas. } 11. Bxa5 (11. f3 Qh5 12. fxg4 Qxh4+ 13. Kf1) 11... Bxd1 12. Rxd1 Nxa5 13. Bd3 O-O 14. Kd2 Rfd8 15.
