When I am in tourney's I always play to win, regardless if there are savers.
I have 1 friend in particular that I travel with. Any tourney worth going to in my area is at least 1.5 hours away, and usually requires a hotel room. So we have an agreement in place before we go. Depending on the tourney, we have a couple types of agreements. 1.) 50-50 regardless of anything. 2.) If 1 person gets in the money, its 25% to the other, unless he wins the tourney, then its 50%.
Since payouts are so much higher when you get 1st or 2nd rather than anything else, we just cut it even if we win, but if one of us takes 4th for example, it is worth our time instead of splitting a small amount evenly.
Winning is the main goal, regardless, but we want it worth our time if we know that we are going to have to play each other.
