Probably, the thought of watching, 'chess-boxing' mixed age competitions; Between those players, lucky enough to be in their 'forties'; Vs. their 'sixties' decade, elders. ..{weak joke; if manifesting.. Too much, 'time-to-kill'!}.
Favorite Chess Variants

I haven't played Looking-glass Chess for forty years, but for a while regular chess seemed dull by comparison.
Kriegspiel is fun, for the spectators as well.

Spartan Chess is awesome because it succesfully pits two different armies against eachother with roughly equal odds.
I have a soft spot for XiangQi (leaving aside losers chess, bughouse and atomic chess, it's the first proper chess variant I learned to play) and Makruk. Capablanca/Gothic Chess is ok, but to me it's not all that different from other variants that add more super pieces on a larger board. I have a fascination for Tamerlane Chess, but so far I've never played it (I normally just make computers play these variants) and suspect that the game is actually quite dull in practice...
I find the mentioned variants to be a bit too gimmicky: Fischer is just the same game with shuffled pieces and obnoxious castling rules, 3-Check and King-of-the-Hill have somewhat arbitrary extra rules that to my taste don't add much to the game and Crazyhouse lacks the fun part of Bughouse (playing with a partner) and is inconvenient to play over the board.
Hello everybody! I'd like to introduce a developing game called "The towers fall" which is inspired by the game of chess and which research players to test it and if necessary to help balance it. I hope it will interest you!

Scottish or Progressive Chess, Giveway chess, Knight Relay Chess, Co-Regal chess. Years ago I was chess variations and non-chess game tournament director for the NOST (kNights of the Square Table). Would enjoy hearing from others as I'm creating a website devote to chess variant games and chess problems
I am looking forward to see your website. Note that I hve developed an 'Interactive Diagram' web applet that is ideal for showing rules of Chess variants with unorthodox pieces, and can be very easily configured for almost any variant. (E.g. http://www.chessvariants.com/invention/elven-chess ) You would be welcome to use it on your website.
In the future I might even expand it to become an actual computer opponent, rather than just a passive Chess board.
Unfortunately not. Ralph Betza already seemed to have retired from the Chess-variants community when I made my re-entry into Chess programming in 2007, after a 25 year pause. I don't know what has become of him.
Mr. Cohen's name I had never even heard before. I looked him up in Wikipedia, and he seems to be a quite productive inventor of Chess variants.

Bughouse. It is totally awesome! One of my favorite activities in Bughouse is to go on the "Queen Hunt". I drop pieces to hunt the queen (only if my partner is super-good at chess and gives me a million pieces)
What is your favorite chess variant?
Live 960, 3 Check, King Of The Hill, Crazyhouse, or Other?
