Ok wow.. I'm red-line madness.. and even I wouldn't do any of this stuff.

Agree with most of bode's comments.

Hand 1: He's IP, I think if he had anything remotely playable he might even peel your 4bet IP given stacks, so once he 5bets.. I don't know. You're screwed.

Hand 2: agree with bode, your riving sizing is completely unnecessary. c/r to 70ish would work just as well. I have no idea why you perceive this as remotely a good spot to bluff though. His line completely resembles Ax.. I don't see how you figure he doesn't have Ax here. Makes no sense.

Hand 3: whatevs... I don't think he's that strong based on his river sizing.. but I also think he can convince himself that his sizing caused some spew.

Hand 4: sure it's fine sometimes.. some ppl might look you up with worse here... some rivered Qx or something. It's thin but way better than the other 3 hands.
