Show the hand or not?

I show in the mood. Sometimes because I was one of the players showed their card. I also show to deceive opponents, that we could make a bluff Smooth Function in the future. Generally show the card there are many reasons. Do not show only one - not to betray their tactics.

I always show the cards when I'm bluffing, you're going to tilt everyone )

I never show. Poker is a game of information and even when you do so by trying to mislead opponents, that in itself is still giving away information that I'd rather keep to myself. When playing someone who hasn't shown his cards the entire game and all of a sudden he reveals a monster, I don't think "oh, he must have great cards all the time", I become suspicious. I just think he's trying to set up a bluff, which is what they usually are doing
