To me check raising the flop is fast playing BUT it certainly screwed me here. Thoughts?

I used bet the pot format. Which one works to show colors?

What really frustrated me also was my check on the river because of the 3 diamonds and 56 89 board. I feel weaker than weak when I do crap like that. :x

On coordinated boards sometimes better off betting with bottom 2 into a big field in hopes that it gets raised by a draw or Ax allowing you to 3 bet it.

I'm pretty sure you're much better off bet/folding the river then check/calling which I assume was your line.

I concur

Yep, lead that pot.

You'll get calls and hopefully raises from Aces and flush draws, letting you get 3 bets in
