Hand 1. You don't have enough to do anything else. If you're beat here that's too bad.

Hand 2. If you think his pot-sized bet means better than TPTK, then go ahead and ditch. But he could have say Ac Kx/Qx too.

Hand 3. I do not understand your turn reraise. It's not especially draw heavy, just call?

I guess you have reasons for being shortstacked, but I don't especially like it.
