String Quartets (Brazil) - Hennie Schaper

King's Indian Defence

1. c4 Nf6 2. g3 g6 3. Bg2 Bg7 4. e4 d6 5. d4 0-0 6. Nc3 c6 7. Nge2 e5 8. 0-0 Nbd7 9. Re1 Re8 10. Bg5 h6

So far it has been a reasonably normal sequence of moves for this opening. White's next move is not a real mistake, but conceding the bishop's pair in a position that can be ripped open any time may not be the best idea either.

11. Bxf6 Nxf6 12. dxe5 dxe5 13. Qxd8 Rxd8 14. Rad1 Be6 15. b3 Kf8 16. f4

This is a real mistake though. Black's knight can now exploit the weakness of square e3. A move like Nc1 would have been better.

16. ... Ng4 17. Nc1 

Tempting but wrong. After Rxd8 black is a bit better but white still has plenty to play for.

17. ... exf4 18. gxf4 Bxc3

And black is a piece up with all kinds of additional threads. To my surprise white offered a draw, but before I could answer, he resigned. Later I found out that this was his first game on the site, so I ascribe it to hitting the wrong button. He was clearly no chess newbie given the solid opening play - and the start ranking of 1600 assigned by the site.

0-1.
