I'm definitely reraising here, my question is, how much? Villain is the worst player at the table, a 36/9/.3.

raise to 33 and fold to a river shove.

$50/fold to shove? i agree he'll call w/worse, but I can't see him 4-bet shoving the river w/o a flush.

[DirteAA]

His AF is 0.3? I would probably raise to ~$35 and fold to a 4-bet too though.

[tubasteve]

keep in mind the af is only over like 50 hands

[terp]

don't worry about exact AF here. if he's stupid, this is an easy raise/fold.

[chiTown22]

Make it $49 and fold to a shove.

how much terp???

i was thinking kinda big, because i can see him having KQ a lot and never folding it, but im not sure. higher flushes are def in his range.
