There was a YT video with Phil Laak recently where he had an Ac8c, and his opponent had an 8s6s, and the opponent/amateur did what I call, "going to Hollywood", he announced his raise to the dealer in order to grab the lime light. Usually what I call "Hollywood" is a very strong hand, but not in this instance. It appeared to be a tell, but it seems very player dependent, and takes more observation than most tells.
Yes, here it is from your thread:
Looked at it again. He announces a pot-size bet, though it's a NL game. It seemed unusual/significant.
