Okay I'll try to figure it out.
Let's say his 3b range is this:
nl.pokerstrategy.com
Equity Winst Split
MP2 55.42% 39.04% 16.38% { QQ+, JdJh, JdJs, AKs, AdQd, AhQh, AKo }
MP3 44.58% 28.19% 16.38% { AsKs }
To go broke we need 48%. We can't go broke and his range might be QQ+, AK only.
Call pre because of the odds. As said I'd fold AKo probably, what do you think of this?
Now let's give him the same postflop range but without AK cause he wouldn't bet (quickly) and big with it on this board:
nl.pokerstrategy.com
Equity Winst Split
MP2 63.79% 63.44% 0.35% { QQ+, JdJh, JdJs }
MP3 36.21% 35.86% 0.35% { AsKs }
We need 45.5% to go broke (raise/broke) in this spot. As I thought we don't have this much EQ.
Now can we call? It's pretty hard to calculate howmuch we exactly have to win from him (our implieds) because sometimes he x/f QQ on and A turn or sometimes the board pairs and we have reversed implieds. I'd say we have to win about an extra $15 at least ones we hit our flush. I think such a fishy guy is never folding any hand here on any turn so I think a call is def. doable.
Did I convince you?
