Probably the most interesting spot of the night for me. UTG is TAG and a regular, seems competant. Other two villains are unbelievably donkish (guy UTG+1 is same guy from A5 hand, other guy is like playing 95% of hands after 30

). Btw, pre-flop call was to hit big and stack off the noobs.
I felt I have next to no showdown equity here, so I bluffed. How much respect should it get? Is this ok?
Again, comments on all streets (including the speculative pre-flop call) appreciated.
