1: i could really go either way but probably just 3bet get it in.
2: if you have seen him do stupid shit like this with middle pairs, gut shots, etc. then i call. otherwise fold.
3: i mean...after raising the turn folding seems pretty silly with the equity we have.
4: holy good god your 3-bet size and flop c-bet is bad.
5: i really don't get what you're doing...why did you flat the button raise, and just call the squeeze oop? it's such a typical squeeze spot that if i decided to flat there (which i would only do if bb is just a retarded squeeze monkey, and even then probably not), i would 4-bet get it in.
6: bleh, fold. and once again, your 3-bet size is too unnecessarily large.
