Fair 3 way game solution

In 1971, 3 man chess became a feasible game. Before that date, 3 way chess existed, but was very unbalanced and unpleasant (similar to 1v1v1 in afterwind). Robert Zubrin came up with the idea that whoever is first to checkmate one of the other two players wins the game (or alternatively takes control over the units of the eliminated).

The result of this idea ends up making an actually balanced gametype. Whenever the strongest player is about to Checkmate the weakest player, the second strongest and weakest player will ally up against them (or face loss).

The implementation of a system/victory option where the capturing someones capitol wins the game would make 3 ways feasible, and even enjoyable
