Live 2/5 NL 200 max buy. All stacks are between $150 - $200. Literally the first hand dealt at the table. There were 10 names on the list and they formed a new table. I only recognize one other player at the table who is a certifiable maniac. No reads on anyone else.

One limper in front of me and I get 6-6 in MP. I call the BB. Maniac limps, CO limps, button limps, SB completes and BB knocks.

Flop ($35): A - 6 - 9 (rainbow)

Checked to me. I bet $15. (??)
Maniac raises to $35.
CO calls $35.
Folds back to me. I raise to $135 (??).
Maniac insta-folds.
CO calls all-in for $10 more.

CO shows A-7 for top pair no kicker. MHIG.

Now for the question. I was talking over the hand with a buddy whose opinion I respect, he suggested just calling the raise to induce a second barrel bluff on the turn from the maniac. Did I leave money on the table by raising in that spot or was it worth it to gamble that the gutshot straight wouldn't complete on the turn and go in for a C/R there?

Thanks
