Hi,

hand 1: I would push preflop, I have no idea why villan reraised you with JT when you clearly show that you are pot commited, with these particular donkeys you just need to prove it to them preflop to either call or fold.

Hand 2: This is pretty well played, I sometimes prefer to push this hand preflop when the table showing a lot of will to call.


Hand 4:Again pushign this hand really depends more on the table and how loose it is, if you think that they call down with a large percentage of hands then you need to fold.
otherwise a push is okay.
