What is villain's non-
bluff range here? 77-AA?
You have 46% equity.
Plus some fold equity, though not a lot, as bean says.
Plus some chance he is bluffing with overcards.
81BB in the pot. 111BB in your stack. I shove. You are not delighted to be in this spot, but your equity is much too good to fold with these pot odds. And calling is only going to set you up for difficult decisions on the turn.
With a hand that has lots of potential, but is not yet a made hand, we want to see a river if possible. And by check-raising the villain has given us the gift of ensuring that we can see that river.
I think the c-bet was fine. It's true that you may fold out some of the A
x hands in the villain's range, which is not desirable, though not terrible either.
The problem with checking back the flop comes when the turn card is not a spade, not an Ace, and not a King, and the villain bets. Where are we in the hand now? Is villain bluffing or semi-bluffing because we were passive on the flop? Or do they have a made hand that will make our draw-plus-overcards hand too far behind to call profitably now, with just one card to come?
We were checking back to realise our equity, but a big chunk of our equity just vanished, and now we have created a difficult decision for ourselves.
If we c-bet the flop and the villain called instead of check-raising us:
We can confidently fold the turn if the villain bets and the turn card is not favorable, escaping somewhat cheaply. Villain has shown real strength by putting chips in on two streets.
If villain checks the turn and the turn card is not favorable, you can semi-bluff c-bet here, or check, depending on villain's tendencies.
We are calling or betting any favorable turn card.
As for balancing our checking range on the flop, this is the micros I think? Huge player pool and most of them are not paying close attention.
Pre-flop balance is easier for a micros player to track, as many have HUDs. They are often smart enough to fold their medium-strength cards to the nit's pre-flop raise.
Post-flop, memories are short.
