This came up in a game recently, and became a topic of discussion after the game. The game does not have rules to cover this, but the discussion concerned making or adopting rules. If your game has rules about this, the answers might vary greatly, so I'm not necessarily looking for a right or wrong answer. I'm just going to pass the feedback along to the powers that be. *** “Bill” and “Joe” (not real names) are the only two players left in the hand. On the river, Joe checked. With a fair amount of talking at the table, Joe thought Bill checked, so he lays his hand face up. Bill look at it and says, “I hadn’t bet yet. This is really unfair to you since I now know what you have. I will show you my cards. But I’m going all in.” Joe doesn’t call. Bill scoops the pot and mucks his hand without showing. Should Bill be required to show? Should the dealer or table captain have turned over his cards? How would you deal with this? This was a source of discussion the next day. Not everyone sees it the same way, and not everyone who shares the same opinion has the same reasons.
