4NL - Open Ended Straight Flush Draw

Anything known about opponents?

I would probably lead/call the flop and check/evaluate the turn when raised. You've got a ton of equity here with 15 outs so you want to start building this pot, and leading 4 way looks hella strong so you'll be taking it down really often.

But I'm not a FR player, so may well be totally wrong.

Three words that go through my mind on this flop... bet, raise, jam.
