[Iconoclastic]

My read probably wouldn't have been JJ, but I'm a firm believer that you win and lose with your reads so you gotta go with your gut. Your immediate instinct was to fold-prolly the right play.

Based on your written account and fleshed out with my own imagination, my preflop read would have been nonhigh PP or medium/low suited connectors, in addition to high PP and high Aces. I don't really like the raise to 6400 as you're still giving odds to a PP for a set and a chance for players who read you as tight to outplay you postflop. He could very well have called preflop with Aces- I do it quite often myself to trap lower pairs or high cards. Depending on his reads he might have pushed the Flop with any of the following- bluffing with a PP or stone cold, a 4, a Q, or a high PP. I doubt he had a FH or quads because usually one would not play that fast.

Your pot odds in this hand are about 30%.

Looks like a call to me.
