I have seen that in the poker world, they have happened to come up with a 5
game event they call HORSE as a tournament: Hold'em, Omaha, Razz, Stud,
Eight or higher stud.

Well, on this note, I am curious what people would think of as a 5 game
chess variant tournament, each beginning with the 5 letters.  The object
is to have a range mix of games that would offer a good sample.  Each game
begins with H O R S E, for each event.  You would want avoid events that
are too similar, if possible (my view that having Hostage Chess and Shogi
would be too close).  So, this being said, anyone have proposals for what
the 5 games can be?  I will list ideas I have here:
H: Hostage chess, Hexagon chess
O: Omega chess
R: Rococo, Round chess, Rollerball, Random(960)
S: Shogi, Smess, Shatranj, Shatranj Kamil, Shatranj of Troy, Skirmish
E: Extinction chess

Anyone have any other ideas?
