What do you think he has?

[slapdash]

Near the end of the rebuy period in a 6-max $10 rebuy. I have about 40xBB, Villain has about the same. He's been playing pretty recklessly recently, obviously trying to build a stack. He raises to 3xBB on the button, you reraise to about 9xBB in the big blind, and he calls. Flop is KKJ, rainbow. You bet just over half the pot. He thinks. He activates his time bank and says "QQ" in chat. When his time's about to run out, he goes all-in. What do you think he has?

Re: What do you think he has? Kx...He's representing weakness which should be a red flag, although a relatively rookie spot.
