1. b/f flop
2. which one is villain? There's 2 in there. I'd raise more preflop and c/f flop
3. RR small or something to make him spazz/call with barely any stack left. I guess calling him down couldn't be bad since he's so short.
4. Bet a tad more on turn. I guess fold river? I don't know. I just don't see the one pair hands he can have waiting for the river to do this.
