KTs on inside str8 flush board

[Peter]

Button capped J4s preflop before, so he might get crazy sometimes.

BB checks...

Some possibilities:
If I bet and it's one raise to me, I guess I should call.
If I bet, button raises and BB 3bets, then what?
If I check, button bets and BB raises, then what?
If I check, button bets and BB folds, then what?

This is a very easy bet/call. TONS of worse hands are calling you down.
