$150 NLHE MTT: Blind war, top pair in tricky spot

[Rajten]

GG master 150$

10 level, 77 min to end of registration, we have almost 2 beginning stacks 50 bb, we got second stack on table.

6x folds, sb calls 1bb (80bb stack), hero Ac7d (50bb) calls

Flop (4c2sAh) 3bb
sb bets 1bb, hero calls

Turn (4c 2s Ah Js) 5bb

sb bets 2,5bb, hero calls

River (4c 2s Ah Js 3c) 10bb

sb check, hero bets 4bb, sb raises to 16bb, hero?

Now I hate myself for betting, but what to do. It looks like 55 mayby some other 5, I don't thinks that he reraises enough often on this board with A with better kicker, even two pairs.
Mayby he, felt the weekness and decided to bluff.

Do you calls here? Do you bet on river?

What do you think about this hand overall?

I think it's fold. But I think you play very passively at preflop, flop and turn. I would punish the limper on the flop because that obly the villain to raise or fold preflop when he is on the sb against you that will make he have not so many spots to explore his low value initial hands equity. On the turn is fine to reraise because he has in his range hands that conect with the flop and lose to your hand. If he would reraise, so you would fold. On the turn playing like he played, he could have hit some Jx, even they are not so many, a call is ok. On that river, his range is only great value and pure bluffs and it is your fault. Now you just can fold and cry.
