hand 1
-I don't mind raising flop. I don't think this is a board where ppl are going to go crazy bluffing, cause your calling range has a lot of strong hands that won't fold to barrels

Hand 2
-I would raise river, he has lots of Ax and worse two pairs

Hand 3
-I don't know about a river check here. Most of his range is some pair, and will check back. What is the value in checking? He might not b/c a c/r with Jx, so might as well bet

Hand 4
-your line doesn't seem to bluffy, not sure he expects you to fold here, I'd fold

Hand 5
-I'd expect two pair+ to bet turn often, so I'd 3bet this river. Being on the button he has a lot of worse 4x hands

Hand 6
-good, hard to misplay it. Think any line you take here can't be too bad. Jamming turn sometimes or waiting to river.
