I'm a 2000 Fide player and I played an interesting opening game last sunday.
It was a King's Indian Samisch (I was playing white) and my opponent played the c5 gambit. That was the first time I saw this move.
[FEN ""] [StartPly "11"] 1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.f3 O-O 6.Be3 c5
I accepted the gambit and was not happy with my position. Both sides played not so accurate moves and I ended up winning a piece.
But analyzing the game, either Stockfish and I seems to not like the position.
Here is what happened
[FEN ""] [StartPly "11"] 1.d4 Nf6 2.c4 g6 3.Nc3 Bg7 4.e4 d6 5.f3 O-O 6.Be3 c5 7. dxc5 dxc5 8. Qxd8 Rxd8 9. Bxc5 Nc6 10.Be2 Nd7 11.Be3 Nde5 (11... Bxc3!? 12. bxc3 Nb6 13. c5 Na4) 12.Rd1?! (12. Nd5! e6 13.Nc7 Rb8 14.Rd1) Rxd1 13. Kxd1 Na5 14.Nd5 e6?? (14... Nexc4) 15.Nc7
Does white have better lines when accepting the gambit? How do you play against c5 (d5 for Benoni like positions or let the status quo hoping for sort of maroczy bind, or something else?
