So, I'm gonna bring this up once and then leave it:
How much, when we are computing things like our equity, implied odds, etc., do you think we should factor in A
K
into Villain's range?
That hand actually makes perfect sense for Villain to have. It explains everything: the large raise preflop, the half-pot value bet on the flop, and also the suck bet on the turn--he's no longer betting to protect his hand from draws when he has the nut draw.
It may be the case that Villain has other hands in his range such as KK-JJ that make check/raising worthwhile. But I think that if we check/raise and don't get a fold, we have to be concerned that a large part of his continuing range is A
K
. And out of position, we will not know what to do if our turn raise gets called, unless we hit an offsuit K or 9.
