When I think of the players who are difficult to play against, they are the ones who take down pots but NEVER show anything they don't have to. It's a puzzle that can be hard to solve. As soon as you give free information, you've given out some free clues to your play. Since I find the no-show players to be the biggest puzzles, it follows that I want to use that technique myself. Never show. Never.
Players who feel the need to show off their bluffs are merely satisfying their own egos. Creating a bad vibe? Maybe. Perhaps it would be enough to put a tilty opponent over the edge. But who are you fooling if you do that? Any decent player knows exactly what you're up to. Thanks for the info, I say.
It's much more effective if you can pull off a good bluff and leave them wondering.
However, if you're sure you want to show off one card, you can do it on Carbon.
