Villian is very solid, have never seen him spew and he seems to always have the best hand. $500
SB is a losing player $200
Hero has a solid image and has played against V a lot this past week $500

Folds to button (V) who raises to $17.5.

Scenario 1
SB folds, BB (Hero) has KK85 hearts to the 8. Hero calls. Pot is around $36.

Flop comes K-Q-2, K & Q are spades, 2 is diamond.

Do we have a check raising range here? If so, is top set no blockers no draw included?

V bets $14. Should we CR pot and if we do, what do we do on a draw completing turn? Or is this never a CR because of so many bad cards?

Scenario 2
SB calls $200 eff, BB (Hero) calls. Pot is around $50.

Same flop, checks to Villian who bets $19. SB calls, leaving $163 behind. If we decide to CR, is pot better or should we raise to around half of SB's remaining stack?

Turn question - what is your plan on a draw completing turn? flush and straight...

I think the sizing of 40% pot suggests he doesn’t have Low showdown value / high equity draws which are the worst ones for you to be up against so I’d raise. There are a lot of bad turn cards but it’s not like he can just barrel off on a spade turn (and non pairing river) when you check because you should also be checking a fair bit when you turn the nuts or second nut.

And adding a bad player calling in the middle makes it way better to raise. Very easy for him to have a hand like KJ92 and call off, and very likely that the button checks back blank turns. If I did call it would be with the intention of donking on blank turns. I just don’t expect the button to bet again vs two players often with hands that bet 40% on the flop.

yes top set (the nuts) is enough of a hand to raise

Fine but say turn is 7s, what is your plan? Are you cc both turn and river?

Depends on the size of the bet. We are going to be 3.4:1 against improving to the river.

3.4-1 assumes we don't know his hand, but if we're behind, at worst, he has a 2s in his hand, so we have 9 outs to improve out of 42 remaining i.e. 3.7-1, but more likely we have 10 clean outs so 3.2-1.

We don't know his hand.

Everyone is lazy. Surprise for poker players.

You pot to $64 and he calls and there is $192 in pot and $434 behind at 2-1 sPR effective.

If he calls I would narrow his range to flush + some straight draws most of time and some non-flush wraps some of the time. AJ10 type no flush hands should call $50 getting this price. However how many of those hands does he really have raising the button? I think less than flush draw type hands when he continues.

So a spade falling is 1/5 odds and I think you can narrow him to spades when he flats. Otherwise he would repot the flop with a value hand to go with a draw etc.

How to proceed on the turn and appropriate bet sizings is another question. I think that is more player dependent but you should be ready to check some straightening cards he may bluff at some of the time etc and have a plan ready based on his tendencies.

If we're behind, then we know 2 of his cards. It doesn't matter that we don't know the exact cards, but we can remove them from the deck.
