Sorry, the hand history has disappeared somehow..

Blinds are 50/100, I have ~3100 in chips.

I open for 400 with KJ from 2 off button. CO calls.

Flop QJ6 rainbow.
I check.
He checks.

Turn 9, putting a diamond flush draw out there.
I bet 400.
He calls.

River offsuit J.
I bet 700, leaving me with 2000 chips left.
He pushes.
