Caught in the middle again.

[mongidig]

Folded to Maniac in cutoff who raises, Called by Super Lag from previous post who calls on the button, SB reraises(once again has a bet and a half left to go all in) I am in the BB and decide to just call with 9d9s. I am 95% percent sure that either cutoff or Button will be capping and I think it is best to let them keep the initiative so I can check-raise a favorable flop. Surprisingly, the maniac just calls but the button does not dissapoint and caps.

The flop: JcTc7s

BB bets(all in) and I am next. Do I get involved here? It could get expensive with these two. On the other hand, I may have the best hand and I do have a gutshot draw.
