JT isolation - how you play it?

Donkbetter is a 74/0 monkeydonk who I'm trying to play as many hands as possible with... rest of the table seems passive. 20/5 types. I havent seen this guy donk out like this before.


Flop play, and plan for rest of hand?

Easy raise, if he wants to get it all-in oblige him. If anyone else wants in be scared.

$20. He has a flush draw or some shit like A8 85% of the time.

stack sizes are awkward but just raise
