Staking of "horses" is very prevalent in the world of poker. Many players simply don't have the bankrolls to play at the levels that they want, while other players are simply looking to minimize their risk (even a very good player with a sizeable bankroll can go broke on the poker tournament circuit pretty quickly, especially after considering travel expenses, etc).
Staking of "horses" can be a very profitable activity. It's obviously of the utmost importance to select honest and talented players - many stakers have been ripped off by "horses" that have failed to honor the terms of their agreements.
