Eventually, i doubt about reasons to play with your "alt" in tournament. It's not a bounty campaign.
It means you have Twice the chance to win instead of 1 chance like others.
bounty campaign or not, you sound like a scammer johhnyUA.
It's not even only that twice the chance , it's also the fact that he will basically know +2 cards each hand which will give him a huge advantage over the other people.
