In a recent article in Card Player magazine, Barry Tanenbaum gives compelling reasons why you should show your hand :
• You might win.
• You might have misread your hand.
• You may get to see your opponent's hand.
• It speeds up the game.
• It's OK if people see your hand.
Had I read the article a few weeks earlier, it would have saved me a lot of anguish and a couple of hundred dollars to boot.
