Live tournament, myself and Villain are battling for table chip lead, each with a very large stack.

200/400, 7 handed, early on (nowhere near money yet), about 44k effective. Playing at a very loose/passive table, LOTS of limp calling 7bb raises and so on. Villain slightly less so, he can find folds but likes to see flops.

Villain limps UTG, fold, I raise to 2200 with AKhh, folds around to villain who calls.

Flop: A84 all diamonds

Pot - 5k
Villain checks, I bet 3200, villain calls

Turn: 4 of spades

Pot - 11.4k
Villain checks.

My thoughts here are he very likely has a pair with a flush draw and sometimes a strong made flush. I feel like he would have raised any weaker flush he could have hit if he would limp call something like T9dd preflop for that much. I do like my preflop sizing, maybe even think it's a little small, as people are so likely to call and there were still 4 people left to act behind and they were the loosest at the table. Unfortunately I didn't get any action from them. Villain could also have a hand like KQ, KJ, 98, T8, 87. He gave a bit of pause before his check on the turn, I'm not much for live tells but it seemed like he was unhappy about the board pairing. If he has a pair and a flush draw he now loses his 2 pair outs and if he has a flush it is very likely I just boated up.

I just think it's very difficult for me to have a full house without pocket aces here. I also don't see myself having many flushes. Maybe KQ, MAYBE KJ but I think I'd rather just limp behind preflop because it's so likely to go multiway anyway that I would much prefer the extra money in there.

Thoughts?
