A08 King's Indian Attack (1.g3 d5 2.Bg2 Nf6 3.Nf3 c5 4.O-O Nc6)

A08 King's Indian Attack (1.g3 d5 2.Bg2 Nf6 3.Nf3 c5 4.O-O Nc6)

This is a rather old game, played over six years ago at Chess.com. At that time I was still creating open challenges and this is one of them. The game went wrong for me on move 11 when I moved my bishop to d7, which was passive and I should have gone for the aggressive square g4.

Armenia123 found the strongest reply 12.dxe4 and then I made the game losing blunder 12...Nxe4. A better alternative for me was 12...d4, but even then I would have been in serious trouble. The move 12...Nxe4 is a horrible move because it loses a piece by force. Had I not moved my bishop to d7 and ruined the connection between the queen and the bishop on d6, then the move Nxe4 would have been a playable option. The game ended with the moves 13.Nxe4 dxe4 14.Qxd6.
