How else could i have played this sorry i don't have hh. $12 mtt on tilt 1100 entrants about 500 left i have over 6k in top 100, 2nd in chips at my table. average is 4k. Folds to me with just the button, sb, and bb left to act. blinds are 60/120. i raise to 320 with ak off sb and big stack in bb calls. flop is k 10 7 rainbow. Checks to me i bet 750 into 1k pot or so. sb folds, bb calls. Turn comes A still rainbow. He checks i bet 1800 into pot of 2400 or so. He pushes me all in. He has played a ton of hands and somewhat wild. He shows QJ for the straight. Can i really put him on callin with the weak draw. I mean thats a lot of chips to call off for 4 outs assuming no one folded an ace. Or am i just supposed to bust there. Please help, any feedback is appreciated.
