20 hands on villain and looks all loose passive (30-5) but I'm not happy relying on that big a sample vs playing for stacks.
pre-flop is stealing this all day.
Bet the flop with the nfd? and odds seem fine to call the checkraise. Should I ever be pushing here without reads?

SB bets $12, easy fold? push is spew?

note stack size here, $12 to get $50ish assuming villain commits to a heart river. I don't expect my ace is an out..
