What combinations does he has, and what probabilities?
Should I second barrel?

[Fletcher19]

yeah, he has like $19 behind and we has to charge the draws!

[Aquadougs]

How low kicker should I have to not second barrel here?

[straightaway]

Your kicker's worthless now, it doesn't matter what it is. I push him all in since he's got like ~20 left, but i'm not super happy about it. I'm def not folding tho

Shove turn, draws will call, so will some pocket pairs. And we're going to split w/ most aces we figure.
