[jrz1972]

When I isolate against a total maniac, I do so with the intention of getting to showdown unless the board is really bad (like four to a flush that I don't have or something like that). So in the situation you described, I hit the "call" key 3-times and go on to the next hand.

I'm not showing down Q-high or J-high, and I wouldn't be involved in the hand in the first place if that's what I had preflop. I'll occasionally show down something like an unimproved KQ though, again depending on the board.
