I obviously meant to push all in on the river, not leave $.25

Should I have bet more/pushed on the flop?

Check/raising this flop after opening for 5BB preflop is like typing "I have KK" in the chatbox, only less deceptive.

I like to c/r w/ trips on drawy flops because that's how I like to play my strong draws too.

Make the turn bet more like 19 to charge the draw more.

i prefer leading the flop.

anyways, played well. sucks if he had a flush.
