There are two very different ways to stake a player. One is putting him in action and the other is putting him in a tourney. The second way (which I've done a hundred times) has less dwn side risk. Usually all expenses come off the top and you split the rest. If you have a good player, you have a chance to do pretty well. I have chopped up a 25K score (with Keith) and a 18K score with Tang. Not a bad return on a $1,500 investment. I had many wins in the five to ten thousand area with the same two players.
In gambling it is best to have a "make up" clause with your player. If he loses it must be made up off the next win. This way you can protect your bankroll.
