<font color="#666666">5 folds</font>, <font color="#CC3333">Hero raises to t600</font>, <font color="#666666">2 folds</font>, <font color="#CC3333">BB raises to t4870</font>, Hero?

Would you call here if you are 100% sure that villain does not have a pair bigger than 66?

I am in the top ten in chips about 35 left in a 180 person SNG. If I win I will be in the top 3 in chips, if I lose I will be average. I feel this is an easy call.

Hand #2

PokerStars No-Limit Hold'em Tourney, Big Blind is t200 (8 handed) FTR converter on zerodivide.cx

CO (t11890)
Button (t4995)
Hero (t5766)
BB (t12434)
UTG (t3368)
UTG+1 (t12925)
MP1 (t4073)
MP2 (t8424)

Preflop: Hero is SB with 9[img]/images/graemlins/spade.gif[/img], 9[img]/images/graemlins/heart.gif[/img].
UTG calls t200, <font color="#666666">1 fold</font>, <font color="#CC3333">MP1 raises to t4048</font>, <font color="#666666">3 folds</font>, Hero?

I feel that Mp1 doesn't want to be called here pushing 4k in after a limper.

I am slightly below average, but still have a M of ten. Again if I am confident that this will be a coinflip or that I am way ahead, this should be a auto call right? I am more worried about the limper, but I feel I need to acumulate chips to come in first. This hand came shortly after the first one.
