Villain is a 40/15 fish. I have no further reads other than stats and I presume this will possible be what makes this hand spew... On the flop I choose to bet since I have good value against villains calling range, I expect the SB (15/10 with high fold to cbet over decent sample) to fold a lot to my utg+1 raise and cbet into a fish. Turn and river thoughts?
