Hey guys I recently moved up in stakes. This is a hand I played today and I didn't know what to do OTR. I open up A2c from Mid and BTN calls. So after him raising OTT I put his range TT, 99, or 33 as a bluff he could be raising with Axd maybe even KJd he could be also raising T9 for protection but I think he would raise the flop with two pair hands. My main concern is that he raise turn with Axd and than just bombed the river when hi has hit an ace. It is hard for me to belive that he would raise like AT OTT or could he? Should I be folding this turn or take a check call line OTT and than see what happens on river. Should I be calling this river is also sth that bugs me... lines like this are under bluffed I think. What do you guys think? How would you play in the same spot? Thanks cheers!
