20/40--flopped set

[JasonP530]

20/40 full table.

UTG raises. He just sat down 2 hands ago and posted and is }30/9/.9. CO(65/26/1.3) cold calls as does the button(45/16/1.2). I call in the big blind with 77.

Flop is a gorgeous T72 no suits. UTG bets, the two turkeys call, and its on me.

Do I make more by checkraising the flop with the 3 of them in(and possibly driving them out if it gets 3 bet by UTG with a big pair), or by going for the turn checkraise on all of them? If UTG was agressive, I would definitely try for the checkraise, as he would be more likely to bet, regardless of the number of people who called. I was a bit concerned by UTG's relatively low agression factor(i.e., he may not bet into 3 callers with AK or AQ again. The two callers could have absolutely anything from a pair to two undercards(and will definately call one more on the flop no matter what).

Should I checkraise the flop, or wait for the turn? I usually evaluate board texture, how likely to have an overpair, how draw heavy the board is etc. when trying to figure out what to do.
