wat do you think guys about river play? maybe it seems a snapcall but i think in this spot my cards are totally faced up. must i ever consider folding here? does your play ever change a,against a nit b,against an unknown?

You should call on the river if you called the other 2 streets, but I think this is a WAWB situation... This line means for me another K which could be better but worse than ours. So that 4 does not really change the board at all therefore the call is the only option I think.

You should call this river. Not sure if you can fold this against any type of player.

against a str8forward, not really aggro guy it's a fold, againts a 10tabling autopilot reg, fold. Againts a random or a fish call.
You can have QcTc, JcTc, 9cxc, QcJc, Khxh, KT+, 66-JJ, simple FD here. And you'll call only with Kx (more likely KT+), so it's a good bluffing spot imho if u play your FDs, cdraws passively, and u can make big folds. So maybe also call against a tricky-bluffy-aggro reg.
Btw he doesn't represent a lot...only AK, KQ, AA, KK, 55, maybe A5s, 99. But you've got a K, and he might slowplay boats and quads, so KK, 55, 99 is probably not really in his range. If he didn't raise A5s, and he won't bet otr with KQ, I would instasnaphyperturbo call him otr:-)
