Pre-Flop: J[img]/images/graemlins/club.gif[/img] J[img]/images/graemlins/spade.gif[/img] dealt to Hero (BTN)
3 folds, <font color="red">MP2 raises to $60</font>, CO folds, <font color="red">Hero raises to $180</font>, 2 folds, <font color="red">MP2 raises to $1,807 and is All-In</font>, it's 1627 to me.

i need to be 44.7% to win to make it 0EV.

fwiw, if villain pushes QQ+, AK then i'm 36.2%. if he pushes AK and QQ i'm 45.8%. if he also pushes some weak hands periodically then my numbers go up quickly.

villain is basically unknown, playing for 20 hands with non-nitty stats (but nothing too out of line). he should not know me unless he datamines.

if this were 6max, villain would be "MP" (1 off CO). i haven't played much full ring at all. in theory CO-1 vs button should be the same whether there are 5, 6, or 15 players (except for the fact that the EP players who folded are slightly less likely to be folding aces, so there are slightly more in the deck).

does it actually play that way? or do full ring players play nittier than 6max in (for example) CO-1 vs button? is this guy ever going to show up with AQ-/TT-?
