not so sure about this hand

If you really think he'll pay off max even if the draw hits, then ofcourse the right play is call/call/allin flop/turn/river but as previous poster said I doubt he is. So when do you want the money to go in? When it's a coinflip(flop) is +ev ofcourse, although maybe not by very much... But what if he pots it on a blank turn? you fold?
As played I doubt you'll get more than 1/2 pot more out of him, which is good considering what you paid but still, I wouldn't count on him giving you those odds on the turn everytime, hence a raise on the flop to either gain a freecard or get it allin right there would be better overall.

Oh and I really doubt he'll call allin on the flop with 88 99 and possibly TT, think of it from his donk perspective: you raised pre and called his reraise, then go allin after his overbet on the flop for another few hundred. That's quite alot of strength right there
