SB is an ordinary TAG. I dont remember much how he plays. UTG is a donk he could have anything really.
On the flop villain is betting 200 into a 30$ side pot. My thinking is that hands I am about 50/50 and A[img]/images/graemlins/club.gif[/img] x combos against are the biggest part of his range. I basically only fear A [img]/images/graemlins/club.gif[/img] Ax which I am absolutely dead against.
