what if 5. c4 a6?
forcing a trade, because if bishop backs down 6. Ba4 i think 6.....Nb6 is good for black.
and if trade, 6. cxd5 axb5 , 7. dxc5 black is down in matrerial but white have no more control of the center, plus black would gains a pawn or 2 back..
Ok, so this is quite interesting and probably bad for black.
tell me what you guys think, how it should be played?
I put an example of a possible trap aswell.
