Ok...playing 1/2 no limit and not in this hand but just an observation. The two players in this hand go back and forth betting as the board grows to an 8 high straight. They had built a decent pot...but at the end...they checked it back to each other. The first player showed that she had the straight before the last card came on but she only showed one card. The dealer told her to show both cards if she wanted the pot. Meanwhile, the other player shows only one card...a 9...giving him a higher straight than the board!! But then...he slides his cards...with just the 9 showing..into the muck!!!! The dealer awards the first player the entire pot...stating that the player with the 9 gave his hand up by not showing both cards. That player got up and left the game..complaining the whole time. I thought he was really being an idiot about it...but then i didn't know why they wouldn't have at least split the pot? The next dealer in said that this was a collusion control measure. I still don't know how the best hand losing was collusion control in this case. Your thoughts?
