1. Button is unknown.
2. SB is a very loose (70% VPIP), very passive straightforward player (only bets 2pair or better, raises PF with the most premium hands, doesn't bet draws, doesn't semibluff/bluff, doesn't slowplay, doesn't 3bet/cap w/o nuts) He is the reason I am playing 5/10.
3. I am in the BB. I have TAG 6max stats (23.5/13.5/2.2). I am aware of SB's tendencies. Also assume that I am playing very ABC poker (not getting tricky).
