Thanks for the concise and well thought out reply.

Question, don't you think he would lead out here with a two-pair type hand that hit the board? I thought he would and this is why I took a lot of two-pairs out of his "infinite" (lol) range. I mean it is 4-way on the flop and he is first to act. Is he planning to check call down with two pair OOP on this board?

I thought he was capable of peeling, that was my read. However, the read can't be proven because the turn was not below a 6 ('who knows' as in I could be very wrong).

Like I said previously, unless you think villain is completely clueless, don't expect him to call your side pot bet light.

Turn is a horrible card for anyone without a straight. Without a side pot in combination of one card straight possibility, you're definitely turning your AA into a bluff.

Most semi-competent players would not call the turn bet in this scenario without draw to at least a higher straight or the fullhouse. So turn is really a horrible spot to bet because you're almost never going to be called by worse.

If you think there are those that would call with worse, then good news for you, there are many horrible players in the room, otherwise it's simply a bad read.

Sorry my spelling sucks.
Would he lead out if he made two pair on the turn? That depends on how he is reading you. If some how i got to this turn and made two pair and thought you were going to fire again and had your range isolated to overpairs then I would check raise to get all your money in and fade getting counterfitted.

OTF. With two pair Im firing at that board for sure. Multi way my hand can get outdrawn often so i want you to pay to draw. But nits don't really think that way. Check raising the PFR seems to be the line most commonly taken here. But two pair and straights are not flopped here to often. So betting the flop is usually correct. What hits this flop hard is the pair plus combos. 10/9 9/8 8/7 7/6 as opposed to 7/9 10/8 and 8/6. Also the gappers dont show up unless there suited gennerally. The connected cards show up both suited and not suited so you see 4x more connected cards then gappers.

If i have Aces in this pot and the flop comes 678 or 789 or 8910. Im checking the flop and hoping for an ACE and then evaulting the turn. But it is hard to bet for value on these kinds of boards. Just get to showdown cheap.

I play in a lot of games with passive lose players so i see this kind of stuff a lot. And the majority of profit in these games comes from understanding there ranges and knowing when we can and can't get value. And when we have to fold over pairs.
