99% of the time is a gross over-estimate
in reality any estimate has a top ceiling of 95% and that's when I say I'm 100% sure (other than when I have the stone cold nuts)

I have the third nuts against a button limper
if he had a suited ace, wouldn't he raise to steal the blinds? Maybe he'd limp the lower end of the range, but it would take a nit to limp ATs+

so he's only limping A2s-A9s
and he might actually dump or raise an offsuit ace, not a lot of people limp those

so that's how I can argument my 90% win rate in this spot
if he has a flush, he has a small one
Q6/Q5/Q2 type of hands I'd say only 5% chance
sets are a distinct possibility since he might be one of those people who limp pairs on the button for set value + especially since he called my raise
I can discount 5s slightly more because he might think that the queen hit me

so let's pokerstove this, I'll put in the most likely hands and see how often he has this

66,22,Ad9d,Ad8d,Ad7d,Ad4d,Ad3d,4d3d
is 1.4%
I'm going to add 5% for all the other crap that I discounted but it can still show up unexpectedly + because we need to weigh the 1.4% figure since those hands are more likely than air
so 6.4% is probably the chance that I'm beat

if he pushes into me needless to say I call a push 100% of the time since I'm getting 3-to-1, so even if his range is weighted heavily towards the hands that have me beat, it happens so rarely I'm getting value from Qx and more importantly small flushes that got counterfeitted

SiCK_Boy, your argument is that I gain when he folds
this is not true, he will not fold a full house or ace high flush on this board, and certainly not a straight flush
and those are the ONLY hands that beat me, he will fold them 0% of the time

so if he's folding, he's folding a worse hand and that's a bad result
if he's checking behind he's also checking behind a worse hand, which is as bad as us going all in and him folding
so we have two good results only:
1. we go all in and he calls with worse
2. we check and he goes all in with worse

on this board, which is more likely?
we actually don't care how often he's ahead because we're paying him off

btw, I don't feel like giving results since they ruin the discussion but PM me if you really wanna know
