Hey Guys,

I need your help and opinions with this hand. Last Saturday night, I was playing a 4-way cash game with a couple of friends with buy-in at $40. I was greeted outside by the host as we smoked a cigarette before going inside. The two other players are best friends, next-door neighbors that I've known for about 1 year. One of the these guys is very talented, crushes most low-stakes games and openly talks about dealing off the bottom of the deck and a book he has read entitled, "How to cheat your friends in poker". So here was the situation. Me and the host came in, sat down and began playing right away. They had the decks "shuffled" although neither of us recall cutting them. The first hand, the host raised and everyone folded. On the second hand, I looked down at 3c-9c, obviously trash, but I limped in anyway. The host [on the button] folded and the three of us saw a flop: 10c-Jc-Qc. First to act checked, 'good player' guy bet $1 and I triple bet him. Then first to act [an extremely tight player] raised to $8. The guy who bet $1 almost folded immediately and threw his hand to my friend [host] who wasnt in the hand to look at and said "look what I folded!" I flat called and the turn brough a low spade. He fired $10 and I thought for a while and called. At this point I put him on 8-9, A-K, and mostly likely an A or K of clubs. I suspected that he had a higher flush, since my 9 high was vulnerable. The river brought a meaningless card and he checked. I figured there was no point in betting as I was worried about a check-raise. He flipped over Ac5c and showed the top flush. This is where it gets shady. My friend the host says, "I folded 4c8c'' and he dug out of the muck his cards. It turns out that the guy who insta-folded after the raise, re-raise had 2c6c and one of the burn cards was a Kc. When you think about it, that means that 11 of the top 12 cards had to have been clubs, while, I know for a fact that 12/13 were. Add that to the fact that we are playing 4 way and everybody flops a flush is ridiculous. I played the rest of the session and chose not to think about the $20 I lost, but was certainly suspect. After 2 days of reflection, me and the host are beginning to think we got cheated. Here are some facts/ Q's:

-First Bettor insta-folded to the raise, re-raise as if he didn't even think about it
-If the tight player check-raised the flop, is it reasonable to assume that he would at least value-bet the river when he knew I had a strong hand just calling him down? I feel as though this may have been stopping on the bleeding without being too obvious...
-Could this have just been a prank gone wrong and neither of them had the balls to say anything?
-Does anybody know the statistical probability of 4 people flopping a flush 4-way of a shuffled deck?
-There seemed to be a lot of acting in retrospect with both of the friends making comments about the hand

So what do you guys think...was I cheated or do I have to give them the benefit of the doubt?
