HU Hand

[theBruiser500]

SNG, blinds of 10/20, he has about 850, I have him covered. He raises to 60 on button I call with Ks Jc, flop comes Kc 6c 4h. I check he checks, turn is Qc, I bet 120, he raises to 300. Board is Kc Qc 6c 4h. I think he could have a hand with just Ac or maybe even just Tc, maybe AK (with or without a club), AQ no club, some other made hands no club. So fairly wide range of hands. Raise all in here or call, with what plan on river?

Shouldn't this be posted in the 1-table Tournaments section? I'd fold though.
