$22, standard call even with crap? 3-handed

[anuj]

Button is weak/passive, forgot stats. Obviously, I raised because the limp looks weak and it's been pretty much push/fold for him.

Villain has 1925 and the other player and I are roughly even with ~5500 chips.

Pre-flop: (3 players) Hero is SB with 4[img]/images/graemlins/heart.gif[/img] 9[img]/images/graemlins/club.gif[/img]
Button calls t160 <font color="aaaaaa">(pot was t240)</font>, <font color="#cc0000">Hero raises to t640</font>, BB folds, <font color="#cc0000">Button raises all-in t1925</font>, Hero...<font color="aaaaaa"></font>.

Pot is 2645 and I have to call 1285. Odds = 2.05:1, should I pull the trigger?

Call and lose, my stack = ~3500.
Call and win, my stack = ~7500 going HU against ~5500.
