I see more and more collusion now and days. If it's at a regular table I just get up leave and send support a note of the players involved, the table and the time. They usually monitor the players then and catch them. If I see it in a sit and go tourney I would do the same thing, but try and get my money back if I lost. I havn't had the problem in a sit and go or tourney yet but I'm sure I will run into colluding players more and more down the road. If you want to see collusion though, go to a big NL table. Like $30/$60. OMG, I see 2 players come into a table with a few guys and it's so obvious they're playing together it makes me sick. I don't tell
titan about them though because I cant be for sure and I'm not playing against them.
