Just my opinion...but for the most part fancy plays at micros is wasted money. BUT, you have to, as always, know who you're playing against. There are some savvy players at micro and a cool play 'may' work given the right situation.
Yet, for the most part you're wasting bets (not betting because they'll call anyways) or spewing chips (trying to bluff when they will call anyways).
The answer is, just like about always, it depends. But rule of thumb, Fancy Play Syndrome (FPS) equals losing money.
