Again, I apologize if I posted in the wrong thread...

its a 5/10 Live fishy game....stacks range from $600 to 5 k, with my stack approx $2500...

utg limps, utg +1 limps, utg +2 raises to 30, cutoff calls, button calls, sb calls, i am in the BB with King 6 of diamonds and i call, early pos players call as well, so 7 of us go to the flop...

$210 in the pot pre flop

flop is 7 diamonds, 4 diamonds, 3 of clubs...

surprising, it gets checked around all the way...free card...

turn is 2 of diamonds...

i lead out for $125...

one guy calls who has been playing straightforward so far, although he just got stacked with a set to a straight, so he could be tilting...

my image so far has been very tight aggressive, showing down big hands everytime...

river is the 3 of hearts, pairing the board...

i really dont know if i should check or lead the river here, so i decide to bet, hoping that a worse flush/straight/two pair calls me, although i dont let him bluff if he had the naked ace of diamonds...i bet $190 and without much thinking, he raises to $625, leaving himself with about $400...i tanked and folded...

he did not seem like the type of player to be able to make a move here, but i could be wrong...where did i go wrong? should i check/call the river? should i have done as i did and lead the river and folded to the raise?

who called is pretty important here I think. UTG or UTG+1 could have checked a set or 2pair(34) on the flop hoping to c/r, while the CO or BTN would likely bet those hands.

utg was the caller

nobody knows what to do in this spot?

fold yo

i kinda prefer check call on that river unless you are happy getting it in. since he is tilting, it seems like he will be betting or raising a lot on the river, whether he has it or not.

Your river bet... If villain is a bluffer or a thin value man, you should check or bet tiny to induce/snap call. If he is a straight forward showdown man (sounds like he is), you should bet bigger/snap fold.
