Slipping in with Kings

[Mikey]

I'm playing 10-20 HE at the TAJ.

I have black Kings in the SB.

UTG limps in and in Mid position Wacky Maniac raises.

Cutoff 3-bets and says "I know I have her beat."
I think if he had Aces or another high pocker pair he would have just kept quiet. Also he has tried isolating her on numerous occasions and miserably failed.

I think for a second and call.

The reason why I call is because I know that the maniac will cap as she has done that last two times, and this allows me to slip in with Kings without even making any noise.

BB folds and UTG calls the 30.

Maniac of course caps it, Cutoff calls, I call. UTG calls.

Now here is my question.


Should I consider capping it myself even though I know the maniac and cutoff will come along giving myself a better chance of winning if I can elimiate UTG for sure, giving myself a better in a 3-way pot or should i not mind UTG coming along for the ride.

In all do you think this is a good play.

I'll post the flop and results later.
