fold turn, basically what urubu and barewire said. if u rly happen to be bluffed there, it will capitalize at a later point in time in a spot when u r indeed at the tp of your range and can correctly call (assuming he isnt running after this)
Due to what op said about villain, i dont think that bluffing diamonds on the river is a good idea. I mean have u ever seen a fish folding a mediocre flush even if the fourth flushcard peels off?
