Villain instantly raised over my flop bet, and left himself 600 (i.e. didn't shove). Obviously he had me covered so it's irrelevant, but thought it was a little weird. I haven't seem him do anything out of the ordinary, and his stats look pretty normal. OPR shows him as a losing player.

What range do we put Villain on here?

My thinking at the time was that my equity is half decent against anything, and a double-up puts me looking good to go deep. On the other hand, I'm a big dog to the nut flush draw and only really 50-50 against most hands.

Also is the continuation bet mandatory? Stack sizes are a little annoying for precisely this reraise shove reason, but a check behind feels incredibly weak.

Any thoughts appreciated.
