Hi, I recently played a Party 20+2 SnG. We were down to our final 4 players. The chipleader at the time asked me if I wanted to split the top two place winnigs (100+60 = 180) into even 80/80. Utility of deal.. Now I ended up winning and taking the 100 but he really wanted me to come to his PRVT room and pretty much chip dump 20 dollars his way... Is this looked upon as illegal by Party?? I understand Utility of Deal is common for some people but I found this too be REALLY fishy and did not want to risk getting screwed by Party. Any ideas, thoughts would be appreciated.
