Hand from last night - action inducing line?

[tpir90036]

Really good live 5/10 game. My image is very tight, which I have been using liberally to take down pots with nothing since I have lost my ability to flop a pair or even a draw in my older age.

Three limpers and the SB completes. I check in the BB with 8 [img]/images/graemlins/club.gif[/img]7 [img]/images/graemlins/diamond.gif[/img]. I have everyone covered and the effective stack size here is $900 but not really germane.

Flop (5 players, $50): 9[img]/images/graemlins/diamond.gif[/img] 6[img]/images/graemlins/heart.gif[/img] 5[img]/images/graemlins/spade.gif[/img]
Interesting. SB checks, I check, super mega clown in MP bets $30. (This could mean two pair, a gutshot or something as stupid as 53s. He is also prone to getting out of line if given rope but will back down if shown aggression). LP calls, Button (slightly weak but non-clown) makes it $85. SB folds. Action on me.

Normally, I would flat call here and lead the turn hoping to get min-raised by the clown so i can blast it. But since there was already a raise, cold-calling here might give my hand away given my image. Just bomb it now and hope someone has a big hand and comes with?

I know how to us my image to take down pots with 8-high. But getting action when I flop the nuts is a little harder since people give me way too much credit as is.

Thanks in advance,
