For the first hand:
I thought that this villain would repop me pre with AA,KK,AK 99.9% of the time, so I removed those from his range.
If he has an Ax or Kx, he more likely doesn't have a diamond, so I probably have 9 outs to the nut flush, so if I'm behind, I have some equity (~18%).
I figured he's play 33-JJ this way as well, where I way ahead (~95% equity, except for 88).
He might be slowplaying a flush, but my checking back of the flop also widened his bluffing range considerably.
Taking all this in, does it justify a call?
I called. He had Td9c
