Here i would never bluff river like the way you did. Its a very bad bluff. I dont think you would ever get a fold here when you bluff river. only thing you get a fold from is Q10, JQ that might call flop with, but think thats very rarely.

You have to think about what kind of hands he is calling flop with, that he would fold on river after you check turn, and I dont really see many hands that he would fold river wich he called flop with. So very very bad bluff. If you are going to bluff here, its better to semi bluff turn. But i think the best thing might be not to bluff, its a bit depended on how the game has been going against this player and what kind of player he is.

Since the hand was played this way, and you got to river its best to check river, you almost never would get him to fold river in this spot. -EV bluff.

I think this is a alittle bit of a frustration bluff, since you had a draw to the nuts on turn and you missed. + that you put so much money in the pot, and there are so much money in the pot that you want to win. Think i see some frustration bluff like this when i play, and i would say that a bluff like this is a pretty big mistake
