Hand 1 - big 3bet IP? I don't mind it if he's a big whale though and gonna call the same range. I check back flop though.. board is really dry.

Hand 2 - I don't mind a turn check here... only pot size bet left anyhow. Jamming is ok too I suppose.

Hand 3 - gross... yah I guess fold

Hand 4 - Bad double barrel card for sure.
