other players may know other hands

I was in a friend’s poker party game. I was new to this group, which I did not know most everyone, and a few probably know each other. The pot is relatively small. At the end, I loss a small amount.

I rate myself a cool math – probability, slow play, not overly aggressive, not all-in pre-flop gamble and tight player.

Thinking back in the game, I think some of the players may share (or reveal) their hands among themselves during the game. I did not caught it, but have the feeling. If they did share their hands between themselves, can they increase their own probability. What can they do to hurt my hand?

they can have a slight edge on you but that shouldn't really matter because they won't really exploit that information really at all. also

it sounds like there are some big leaks in your game if that's your mindset

If you think any of them are showing their hands to people still in the hand, then stop playing with them, stop giving them your money, they're colluding. If they're showing hands to people who have already folded, it's not important.

If anyone is sticking a finger up in his ass or making a cut with a knife on his wrist occasionally, that is a pretty big tell. They could convey such a behavior for example every time they have Ace in their hand so that its easier to catch you if you bluff A high boards. There is also variety of other tells, laughing, nose picking, coughing, sudden bowel movements, consistent SMS sending and recieving, etc. Be cautious.

I am just suspicious and annoy, that's all. Small changes game. I wonder even if they know each other's hand, what can they do in Texas Hold'em Poker, anyway, not much, right? For example, if one make pair or trip or straight or flash, signal others to fold?

I want to stay and hang out there. I am interested to join into some of their activities and projects which may lead to businesses and opportunities. Or, at least getting to know more about do and don't of their ventures.
