Party Poker No-Limit Hold'em Tourney, Big Blind is t200 (7 handed) converter (http://www.selachian.com/tools/bisonconverter/hhconverter.cgi)

MP2 (t870)
CO (t3547)
Button (t705)
Hero (t910)
BB (t860)
UTG (t680)
MP1 (t428)

Preflop: Hero is SB with J/images/graemlins/diamond.gif, A/images/graemlins/diamond.gif.
<font color="#666666">3 folds</font>, <font color="#CC3333">CO raises to t400</font>, <font color="#666666">3 folds</font>.

Final Pot: t700

Late in the SnG, big stack raises, I think my only play is push or fold. Which is correct???
$10+ 1

Given the size of his raise, he either has a monster hand or is looking to pick up the blinds. Either way your hand is likely to be strong and you should push. Already t700 with his bet t800 if the SB completes.

pushing.
