The rule of a single chip raise without declaration is (in my opinion) a stupid rule. All I see it as a way to trap extra $$ into a pot and screw over another player. Its benefits are negligible. In a limit game, the rule has a purpose, but in no limit home game it it pointless. All this does is set up a possible angle shoot and who wants to have an angle shooter in a home game?

This case is a prime example of why that is a bad rule. The CO's intention was to raise the pot. He placed a raise in the pot. Verbal declarations should not be a requirement.

If there is a benefit to this rule that I am not aware of, please let me know because right now I see it as worthless.

That being said, it unfortunately is a rule in this game. If everyone was aware of the rules before the game began, then it is his responsibility to obey them.
