Hand 1:

4b'ing pre seems like the worst of our 3 options, but I agree with the hand choice/sizing/postflop line if we feel playing back at his 3b's with 4b's is ever a good plan.

Hand 2:

Lol, this is such a "how did I get myself in this spot" hand, but I don't really know which street I play differently.

Hand 3:

This one's over my head.

Hand 4:

I don't really see why he can't have just about any of AQ/AK/QQ/55 (20 combos). I guess we're getting a good price, and surely he can't think we're bluffing here lol, so if he has all the combos of AJ/AT and folds them damn-near 100% of the time, then we make a marginal profit here. I personally just fold here, though.
