[TWINUNO]

FTP 22kGTD
Only read on villian was he bet 1/3 of his stack in co+1 and folded to co push. Also seen him double with AQ calling his stack all in.
My image is a tad loose calling a push w/77 at 120/240 (3600) for my stack aginst a big stack and then doubling when i hit a set on AA. I then lost it callign w/88 in BB and having AA over set me.
150/300 antes 25
9 handed
Villian(BTN)4300
SB(2500)
HERO(3600)
POT(675)
BTN raises to 800
SB Folds
HERO?

Ive been debating here if i need to be taking coinflips at this stage and if i kno hes calling with aj+ am i pushing here?

push your m is 6 and you need to make a move to get some chips

(the bet does look like hes wanting a call)

You have a pair against a button raise. Easy push.
