Why? I'd much rather my opponents think I play extremely tight and always have the goods. What's Hero's incentive for inducing them to believe the truth?

Yeah, if you haven't attempted to actually track some stuff at the table in the thick of the action I think you might be surprised at how difficult it can be to keep it up (at least in my experience).

FWIW, last year I spent ten 1-hour samples collecting data regarding how often the pot was raised preflop. Some of the samples I aborted half way thru when I realized I had zoned out of the experiment and forgotten what had happened the last half orbit. Anyhoo, bottom line regarding hands per hour dealt at my table during those samples: 30.4. I know Mike has tracked much higher hands-per-hour-rates in his games (in and around the 40s I believe, which seems insanely high to me), but it is what it is.

I'll show a bluff if I usually don't bluff in that spot. For example I'd rarely bet bet and overbet shove without a strong hand. If a situation comes up where that's +EV, I'll for sure show it to plant a seed of doubt. I used to show 3 bet bluffs when uncalled to get a more aggressive image but now I never do because I 3 bet bluff a lot.

I'll also show if I know villain tilts easily and will spew off chips when tilted. Especially if I don't like villain.

^ id advise against this because you are making your life harder - you wont know if villian is doing something because he saw your bluff or because he has it. As has been stated ITT, this is also a waste of your time. V's at these stakes dont believe enough anyways.

edit: i think your last sentence best shows why you should not do this - you are doing it from Ego. Aweful idea.

This is why you get accused of fancy play syndrome and entitlement tilt. You get into ego battles with the donks at 1/3 and try to "outgamble" them, spewing your profit for the sake of an aggro image. Leveling wars are - EV if you have an edge at the table and want to keep your opponents playing predictably.

Wow some many people on 2+2 need to work on their reading comprehension. I said I'll show a bluff in a spot where I don't usually bluff if it happens to be +EV in that specific spot. I never said I would spew off chips to show a bluff for the sake of image or to level another reg.

I think it was the "especially if I don't like villain" part of showing a bluff. But if there's mutual dislike and it's likely to tilt him I don't see much of an issue. Tilted regs is where most of the money comes from in tougher games.

Personally I don't try to tilt people in a way that would make them dislike me but if it works for you and you don't mind the secondary effects I guess it's fine.
