I don't care about this bishop taking my bishop because the trade allows me to have a central knight outpost
5. Bd3xf5 exf5
Triple attacked e4 square
6. b3 Nb8d7 7. Bc1b2 Bf8d6 8. Nb1c3 O-O
I want to bring my rook to e8 and then have a nice rook on an open file protecting my knight on e4. But first I need to play c6 to protect the single defended pawn on d5 so I can play Ne4
9. O-O c6 10. a4 Rf8e8 11. Rf1e1 Nf6e4 12. Nc3xe4
taking with the other pawn leaves me with a weird double pawn. Taking with the f5 leaves me with a monstrous pawn chain!
12... fxe4 13. Nf3d2 Bd6xh2
?? This is a psychological greek gift/sham sacrifice move I made. This move is also seen in the Stonewall Dutch Defense but is better in that opening. It's another version of the greek gift sacrifice. The idea is to play ...Qh4+ then ...Re6-h6 where I will have a monstrous h-file and many checkmating threats against the king. Better is Qh4, though. The reason why this is a blunder is because it leads to a draw :( , which you will see why on the next few moves.
