We seem to have hit an intersection of logic. The old man could limp AA, KK preflop (the nuts or essentially the nuts preflop) but couldn't check the nuts on the flop (because he's tight)? If he can limp or check the nuts preflop, I would assume he could also do the same postflop in a multi-way scenario.
When hero bets $15 into a $10 pot, unless he's been making this move often, this is a huge overbet (%-wise) and a competent player would know that's a strong hand, and NOT check-raise with an overpair or anything worse than top two.
For those who think we should call and re-evaluate the turn I don't mind that play. But are we good enough to stick with that plan (calling to fold the turn)? I would hate to get to the turn, get value bet on blanks and feel like we have to call again, setting up a river scenario where we feel pot committed. If that's our plan we HAVE to stick to it.
For funs I PokerStoved the hand against the villain's range. I definitely would put more weight to the stronger hands but here are the results for our top two against JJ+, sets, 98s, 98o, 76s, 76o, 8
5
, 5
4
, and J
9
- we are a 51.2% favorite against that range. I was surprised to see how even it was, but I wasn't giving villain much likelihood for JJ+ in my head.
Now, I consider him super unlikely to have 76o from UTG + 1. 98o is also unlikely but whatever. 8
5
is sketchy at best I would say. J
9
I don't think he check-raises there. Against a new, smaller range throwing those hands out our equity actually improves to 56.0% (because we lost the 98o combos to the nuts).
How often is a TightOldMan check-raising us with the lower end of that range? Not often enough, IMO, but I can't say it's a slam dunk.
