its a fold, he is opening a very wide range and a single paired 10 is behind alot oif it.

whats wrong with calling the flop ?

If I hit top pair there I am all the way to the river check - call ? 

it ia  very small range that it beating KQ 

Think you folded   a set to two pair 90% of the time there 

prob playing 72 for   a lark and hit 2 pair.  

Since he is all in you have no real pay off here and only beating an awfully staged bluff. I'd fold

you have one pair.   

The river was going to be 60 ish to call. 

I'd be folding in the absence of good info/history that he can fire 2 streets with a worse hand.
