Hero in CO covers has a tag winning image- has won several 100bb+ pots, raising in position a decent amount showing down winners.

Button 800$ started out aggressive lost a bunch rebought played passively won a bit and is now fit/fold ,passive plays a decent amount of hands, said only plays his cards has folded after anteing a couple times

Sb 200$ 70ish year old white euro hat- most of the time I see him limping all the time. Never raises will stack off light in weird spots. Has rebought for 50-70 bbs several times. Has recently been limping and folding a decent amount. One hand he has 300 and over limped, I raised in LP AKo bb tilted Asian shoved for 245, he called , I put him all in and he had JJ and mhwg after flopping an A. Another hand he limped in mp with about 250. I raised in LP with KQ he called. He check shoved the flop and I called on the Q75 and he had 76o.

Folds to hero in CO with Td8d

Raise to $20-$25.

does that mean there is a 3rd blind otb?
take your usual opening size and raise.

in b4 fold pre

Fold some of the time, raise 2/3rds of the time. Start with whatever is normal for the table, $25 looks good. There is an extra blind but stacks are not deep so no reason to go bigger.

If the table is so loose that $25 is always going to get multiple callers then switch to a 66/33 fold/raise ratio. With the short stacks we don't want to be raising big preflop, better to tighten up hero's range.

Your only real concern is button, since he's the deepest of the three and the one mostly likely to gamble. Also, IP, but that one goes without saying.

Like QuadJ said, raise what's typical for the table like you usually would and plan to lead most flops for 2/3 bet size if checked to.

Yes 3rd blind on the button but I don't think they call it that.

Initially I was raising 5x but 4x in LP was accomplishing the same thing in terms of # of players calling or folding. So I decided to raise 4x.

Hero raises to 20, button, SB, and BB call. Flop is 974rainbow1diamond. Checks to hero

Bet $30. Could be convinced on going smaller, but $30 is salad.

Bet $30-$50.

That should end it. However, I get the feeling that, based on SB's description in the OP and his stack size, he check-shoved on you. If he did, calling this becomes your standard pot odds problem against his likely range. If he check-shoves with second pair again, you have great equity to call his all-in.

Straight forward c-bet semi-bluff situation. $80 in the pot, so $50-$60 looks good, with fewer opponents $40 might be enough but 4 ways it invites too many weak draws and low single pairs to stick around.

No specific plan for turn yet because it depends on flop action and turn card. Mostly though if we are still multiway on the turn I'm looking to check unless turn card helps hero, heads up we can double barrel.

Hero bets 45, button calls everyone else folds. Turn Jc. Hero?

Check.

You have the nuts with very little that can catch up to you. Give your opponent a reason to stick around and extract value from 5th.

The flip side is bet $100-$140 to extract value from 2pr+.

I like $90, you semi-bluffed on the flop and now you should carry through most of the time. You said villain is fit/fold so he should have some part of this and will likely call a small bet. Board is dry and villain is probably drawing thin to dead so no reason to go big.

There are two alternative here. A small probing size bet of $60 could be a good way to get more money in the pot without scaring a single pair off. Checking and going for value on river is also good here if villain has a fold button.

We have Villain covered and are like 800$ deep with him?

I bet rather big 145$ maybe even more if he is sticky with hands that can improve OTR like a T9,98. Checking is the nut worst thing besides open folding.
