Shove over the top with the quickness. He can have all kinds of stuff and you want to get your money in before you get counterfeited. If he has two pair he has two pair, nothin you can do.

[fluorescenthippo]

bottom two pair 5 handed on the turn isnt a good hand really, but at a 10+1 you are probably still ahead. i would push

[bluefeet]

it means "i have 77, and it sucks no one behind led the damn K for me on the flop".

i'd really like to subscribe to the 'you ahead here often enough to push', but i reeeeeeeeeeeeally don't like this much. far more unlikely he was attempting something quite so sneaky on the flop with TP?K. i wouldn't lose any sleep folding to his raise here.

Yeah, I was thinking he had a really strong here too. My logic was fold, and not find out.
So I folded

[bluefeet]

just for the record, a set risking giving 4 others a free turn on FD flop - in hopes that the one person behind them bets on the end here is isn't too much less odd than the way a K is hitting the turn. someone bitch-slapping your rag representation with the nut FD is yeat another possibility. blah...i still fold.
