How do you respond to his pot bet? If raise how much? Do you call the shove?

Thanks

Use the converter.

Raising flop is fine.

Call the push, as your pot odds are pretty good by now.

Your opponent 3-bet pushed, so I'd put him on the following hands:

Against a big made flush, you have 12% equity.
Against AA or KK with a flush draw, you have 34% equity.
Against a set, you have 49% equity.
Against AK with a flush draw, you have 62% equity.

Given all of that you're getting enough pot odds to call.
