check behind...

Either on A2 or A3, or Kx. Only the king will call you, and thats bad, so you gain nothing by betting here. A weird 4 may even raise here, but I doubt hes got a 4.

the missed draw will fold, the King willc all, the 4 will call/raise. Bet is -EV.

"You will only be called by hands that beat you"
