K9+, sets, QQ-99 (less likely), AA (even less likely), 54.

I'd probably have bet like 18 on flop, but now we've been called by a 70bb stack there's only about 2/3 pot behind on the turn so we can't b/f. I'm not entirely comfortable stacking off for 70bbs here so I guess we have to c/f turn, bet river for value if turn checks through.

edit: since he has 70bb I tend to assume he's probably fishy so you can put more stuff like A6 or something in that range.
