1/2 limit, B2B, full ring. This is from memory, but I'm pretty sure the most important stuff is correct.

I'm 4 tabling as always. It's all about clearing a nice bonus. So essentially no reads at all, except that everybody seems ... normal. A little too loose, a little bit dumb postflop, but no reads that any particular player is particularly horrible (or good).

I get AKo in the BB. One EP limper then CO raises, button cold calls, SB folds. I decide to 3-bet. Everybody calls. 4 ways to the flop.

Flop (Pot: $12.50). J52 rainbow. I bet just because I always throws out a CB especially after a 3-bet. EP limper raises. Everybody calls. There's now $19.50 in the pot and it's $1 more to call. Are my overcards live? Who knows? I call.

Turn ($20.50) is an offsuit T, total rainbow board. I have a gutshot to the nut straight. I check, EP bets, everybody calls again. Now there's $26.50 in the pot and it's $2 to call. 4 outs to the nuts so I guess I have odds. I call again.

River ($28.50): K. I didn't catch my gutshot but I have TPTK. I check, same guy bets, other two call again. Pot is $34.50 and just $2 to call. I am thinking the two callers have something like top pair on the flop at best, maybe a pocket pair they can't let go of. I figure if they had JT KJ or KT they would raise at some point. So I'm only worried about the guy who raised the flop and bet the turn and the river. Top pair top kicker, hmmm... I make the call getting 17:1 odds.

Limper turns over 55 for the flopped set. So now I feel dumb. I was basically dead on the flop. Seems like I threw away at least 5 bucks with almost no chance to win.

If I just flat call preflop then I can check/fold the flop and get away from it. Or, after I 3-bet and make the CB on the flop I have invested only $4, so I could just fold to that raise. But I threw away another $5 after that point when I was essentially drawing dead.

How bad was my play? What should I have done differently, and how should I have recognized it?

Thanks.
