Hero is on the button with AA. 3 limpers, Hero raises to $15. BB calls along with all of the limpers.

Flop K67 rainbow
Checks to Hero, Hero bets $35

BB($500) raises to $100. Hero has some history with villain. Villain is a TAG, but I have seen him make some spewy plays in the past.

Hero has $250 behind. Hero????

With 3 limpers, this is probably an easy fold.

6/7 suited or a low set is pretty common in my experience. I think at best, you're looking at an OESD. Or complete spew with Kx.

When you raised to $15 did you think about how many callers that was likely to get?

In the past when people raised to $15 after some limpers did it take down the pot? Go heads up? Go multi way?
My normal raise here would be ~$20.

Bet on the flop can be ok. There are not a whole lot of draws to protect from, but at thr same time if we think we can get more value from KX type hands we should bet bigger. My default would be $50 here.

If you can tell us how V is spewy we can give you a better idea of what to do here.

But I think calling the flop with the intention of getting it in on the turn can be just fine 100bb deep.

TAG calls out of BB and then check-raises.... does not compute.

What's your table image? Does villain have any reason to think you are cbetting too frequently with air?

Against a fish, in my mind, range would be something like K6+, 66, 77. You crush this range ~60% equity.

Against someone capable of a bluff-raise, you crush even harder.

Against some nit capable of slowplaying premiums, with a check-raising range of KK+,AK, you're crushing hard, ~70%.

I guess it's a shove. Added benefit: shoving against people who check-raise sends the right message.

I know it's kind of scary seeing this from a TAGish player, who would likely not come on this strong without a set. But I don't think a skilled TAG checkraises the set here, imo that's kind of a fishy move and so I'm going with the fish range. I don't know if that's right or not, but that's how I look at it.

Villain would have to be pretty spewy to be check/raising this flop with 3 players (all of whom could be sandbagging a big hand) still to react after him.

I believe they have an acronym for that. QFMFT

Raise more pre and bet 1/2 - 2/3 pot on flop. As played and the fact that you know he can make moves stacking off isnt great but with that info I may just station to the river. The only likely holding are 66 or 77 that have us in rough shape. Really k feel the mistake was made pre flop and on the flop.

Game dynamic will dictate whether $15 pre-flop raise is enough, but I don't think it is.

Would a raise to $20-25 have not induced so many calls from the limpers?

I also assume that V2 and V3 folded now that the "action" is back on you?

If that is the case, I like to call here. See what V does on turn/river.

Probably call/call turn and river, don't need to spazz on flop.
