Standard....
165 to call for the 465 already in the pot which you can win...
So:
If you fold : Your left with 165...
If you Call and Win: You'll have a playablish stack of 630...
IF you Call and lose: Your out in 6th...

Your heads up, with fantastic odds, this is the only chance you are going to get really to be heads up, unless acting before you pushes, I think you have to call here, and hope for a low pair or AQ AJ AK so at least you have two live cards....

Standard Call given the odds and the blinds....
