The following position is taken from the Accelerated Dragon :

1.e4 c5 2.Nf3 g6 3.d4 cxd4 4.Nxd4 Nc6 5.Nc3 Bg7
6.Be3 Nf6 7.Bc4 0-0 8.f3? Qb6 9.Bb3 Nxe4! 10.Nxe4 Bxd4

Susan Polgar became the first female Grandmaster at age 15 - and it wasn't luck that got her there. Her use of tactics, combinations, and strategy during her games gave her the critical advantage she needed against her opponents. In Chess Tactics for Champions, Polgar gives insight into the kind of thinking that chess champions rely on while playing the game, specifically the ability to recognize patterns and combinations.

If White tries 10.Nf5, the continuation might go something like this 10...Nxc3 11.Qd2 Qa5 12.Nxg7 Nb5 13.Qxa5 Nxa5 14.Ba4 Nd6, and White will lose a piece because the White Knight is trapped on g7.

If 15.Bd4 then 15...b5 16.Bb3 Nxb3 17.axb3 f6 will win the Knight.

1.e4 c5 2.Nf3 g6 3.d4 cxd4 4.Nxd4 Nc6 5.Nc3 Bg7 6.Be3 Nf6 7.Bc4 0-0 8.f3 Qb6 9.Bb3 Nxe4 Now if White plays 10.Nd5. What should Black do? - I would recommend 10...Qa5+. The the continuation might go 11.c3 Bxd4 12.Bxd4 Nc5 13.Bc4 Ne6 14.Be3 d6 - with a good game for Black.

Black will play ...Ng7 and possibly ...Nf5 and then push his center pawns.

If 1.e4 c5 2.Nf3 g6 3.d4 cxd4 4.Nxd4 Nc6 5.Nc3 Bg7 6.Be3 Nf6 7.Bc4 0-0 8.f3 Qb6 9.Bb3 Nxe4 10.Nd5 Qa5+ 11.c3 Bxd4 12.Bxd4 Nc5 13.0-0 Nxb3 14.Qxb3 d6 15.Qc4 Be6 16.Qxc6

Black should play 16...Qxd5 17.Qa4 What would happen if Black takes the Queen with 16...bxc6??
