This was a nifty little trap i played relatively recently that i thought i would share with all of you. tell me what you think :)

 

- JKO

Watch out for poisoned pawns. And poisoned rooks.

What was Black's idea behind 3...c5??

anti-gambit the pawns back to where there's even control of the center and perhaps exchange queens leaving white uncastle-able.

very nice indeed

 

3...c5 is risky but almost sane compared to some of black's other moves. It at least had the right idea of fighting back in the center. Think the problem is that white can play something like 4.d5 Nf6 5.Nc3 and then e4 not completely sure. The main-line is 3...Nf6 4e3 e6 5.Bxp c5, which black was allowed to transpose to in the game with 4... e6(Nf6) iso 4... Qa5ch?. The QGA is quite a decent opening, if black doesn't attempt to hang on to the "gambit"  c pawn.
