I play in a home tourny in my neighborhood. No Limit $10-$25 buy in. Usually 8-10 guys. I have done quite well playing as the guys love to play but do not have the experience I have. I have found myself dumping in order to keep getting invited back (my wife heard some grumbling in the neighborhood...lol). Here is my problem. When there is a showdown, 2-3 people have gone all in, there have been times where they just turn over the cards and let everyone see what they have. The table then makes the call as to who has the better hand. Example: I held trips, the guy across from me called my all in. He had no idea he was holding a straight and called with two pair. Everyone at the table saw his straight and said "wait...you win with a straight". Now, I am not one to push things, but technically that is wrong yes? You must call your own hand. If he had not turned his cards over, nobody would have known what he had and I would have won the pot with his error.

So, my question is this. How does one explain this to the gang without sounding like I am a sore loser, complaining of a bad beat etc.? Any ideas?
