C: Your turn check is good. River facing 900, I would not curiosity-call. You are often losing the top board and can easily be losing the bottom board too. Good disciplined fold spot.

D: Flop - I think I’m checking most of the time. Lots of hands beat you on the bottom board and if you are ahead theres a number of bad cards for you. Turn - good River - I might call a small bet but not an overbet. I’m folding.

C: With bottom set but almost nothing on top, avoid inflating the flop multiway—especially when the board is already straight-heavy and your hand has little scoop potential.
