Fold pre-flop

Otherwise, I like post-fop play. If you are going to call
an UTG nit raise with K10s, then:

1) you better extract value from hands that you out- flop
2) Lose the min when you are still behind

Checking the flop accomplishes both of these since your
flop check will probably induce a turn bet with QQ, JJ, and 10's.

On the turn, you either have a value bet from KK or AA,
or a feeler/value bet with QQ, JJ, or 10s. (I think this player bets flop with AK). So about a 2 to 1 hand-ratio in your favor. Call the turn.

On the river- I fold to any substantial bet since a nit would rarely fire a 2nd barrel value-bet with QQ, JJ, 10s.

The intersting question becomes when the river blanks and he checks do you value bet? Obviously you can't bet that much since he most likely has an underpair to your K. But I think to make your pre-flop call ok, you need to add some extra value when he checks the river.
