What do we gain from checking flop?
Is it purely because we keep the pot smaller and easier to play on later streets?
I can see a lot of reasons why I wouldn't check here.
We get value from worse hands and draws.
We deny equity by making draws fold.
But I do not understand why this is a check.
Do we keep the pot small because there are a lot of bad cards that can come on the turn?
So if one of those bad cards does come, we haven't invested too much?
I think the idea is that if we’re playing our range, we don’t really have many 9’s/8’s but a lot of junk over cards. So equities are probably equal-ish, even though we have the overpairs and they don’t. Generally even solvers don’t like building pots OOP without a good reason. So I think that’s what’s going on, in theory.
In practice, it can be nice because we have a middle-ish strength hand that will be unpleasant on literally every turn if we get called. Checking also allows the population to get out of line by bluffing with total junk, and bluffcatching is where a lot of our EV comes from with middleing strength hands
However, as you point out, there’s a lot of pros to betting, especially if we figure BB won’t donk very often, if at all, and that BTN will mostly play ABC because of the other player in the hand. I also kind of figure that people will let me know right away if they have a strong hand, and won’t do a ton of slow playing. My guess in game was that:
1) EV of getting called by draws will be higher than anticipated because population will play too passively with them
2) EV of getting called by worse will be higher since we’ll get called by hands like 66 more often than is probably correct.
3) since it’s iggy, I don’t have to worry about my checking range being exploitatively weak
I’m open to suggestions, I think I may have underestimated the EV of bluffcatching total junk, which will just fold if we bet. This hand also shows the disadvantage of tying to go exploit mode and over-cbetting: we end up with the effective second nuts on the river and we’re not thrilled about going for value because villain’s range got narrowed a lot OTF
