In 3 man you can basically make it to the fifty, Just do a run through, they would never expect that...hehe
Besides most 3 man tournaments are newbs so they really won't expect that. Just don't repeat it because by then they would expect that.
I love 3 man tournaments, you can just do anything and get away with it.
5 man and 7 man means more eyes on you and guns, so don't do that kinda stuff unless you can.
