There is a nice implementation of this game and you can download it from this site, but you need to have zillions of games installed on your computer. the zrf plays very decently, I can even say it is moderately strong. The program implementation was not easy, Antoine Fourriere and Larry L. Smith helped me with parts of the code and after the first release I improved the game play of the program with some elaborated tricks. If you have ZOG, try The Travelers, it is a deep, refreshing and magic game. Perhaps it´s not exactly a Chess variant, but at least it´s very close to be.

Yes, blockers are invisible (and only) for capturing purposes

The basic idea in chessboxing is to combine the #1 thinking sport and the
#1 fighting sport into a hybrid that demands the most of its competitors –
both mentally and physically.

This is becoming a very popular chess variant aroud the world, but I must
admit it is a rare variant. In a chessboxing fight two opponents play
alternating rounds of chess and boxing. The contest starts with a round of
chess, followed by a boxing round, followed by another round of chess and
so on. 
A contest consists of 11 rounds, 6 rounds of chess, 5 rounds of boxing. A
round of chess takes 4 minutes. Each competitor has 12 minutes on the
chess timer.
A round of boxing takes 3 minutes. Between the rounds there is a 1 minute
pause, during which competitors change their gear. The contest is decided
by: checkmate (chess round), exceeding the time limit (chess round),
retirement of an opponent (chess or boxing round), KO (boxing round), or
referee decision (boxing round). If the chess game ends in a stalement,
the opponent with the higher score in boxing wins. If there is an equal
score, the opponent with the black pieces wins.
There are some iconic chessboxers in conventional chess world, and perhaps
a very good example is the multi-millionary businessman and politic Kirsan
Ilyumzhinov, best known as FIDE president and president of the republic of
kalmykia, in the Russian Federation.

Checkers Is Solved
Jonathan Schaeffer,* Neil Burch, Yngvi Björnsson, Akihiro Kishimoto,
Martin Müller, Robert Lake, Paul Lu, Steve Sutphen 

The game of checkers has roughly 500 billion billion possible positions (5
x 1020). The task of solving the game, determining the final result in a
game with no mistakes made by either player, is daunting. Since 1989,
almost continuously, dozens of computers have been working on solving
checkers, applying state-of-the-art artificial intelligence techniques to
the proving process. This paper announces that checkers is now solved:
Perfect play by both sides leads to a draw. This is the most challenging
popular game to be solved to date, roughly one million times as complex as
Connect Four. Artificial intelligence technology has been used to generate
strong heuristic-based game-playing programs, such as Deep Blue for chess.
Solving a game takes this to the next level by replacing the heuristics
with perfection.

Well, I´ve been out of scene for a few months, and it is possible I´m not going to be a very frequent visitor of TCVP for a while. Some serious health problems are the main factor (serious, really, but I´m still alive, and I hope so for a  long time). There are some other factors, including seeking what is going on now in my country, Venezuela. I have wrote a few e-mails (in response to others sent to me by to G.W.Duke), explaining some aspects of my health and also some aspects of Venezuela´s current proccess, and my point of view about it´s balance, the good and the bad things, from my optics (in figurative sense, my vision is far from good, as some of you know). 
I am going to come to this pages once in a while, friends, to see what is happening here. Greetings.

I think there is enough worldwide interest in Chess 960, and not only at very high levels, so a well organized World Championship should be a possible idea, it is only the need of intrepid sponsors and federative initiatives, and I believe there are also good possibilities for it. Pretty horizon for this variant.

Man-machine Chess960 exhibition: Svidler played yesterday against the computer world champion Spike, and the result was a draw. Radjabov was beated by Shredder.

Roberto Lavieri wrote on Wed, Aug 16, 2006 01:06 AM UTC:
It seems to be correct, Svidler-Aronian goes on 17th., today have been played other programmed games of the classic. I´m not sure how legitimate is this Chess960 world championship, but, officially, nobody has expressed a different opinion, and the presence od Svidler as defending champion is a good indicative.

I think this games is (perhaps more than FIDE-Chess) very sensitive to openings. You can be quickly in clear disadvantage after some weak opening moves. Some care is needed...

I also consider 'NO' for question number 4, although I differ to you in other answers, as you see. Authors have to clarify.

1.- No.
2.- No.

That's a good idea. We need a new Page, what about 'Ultima Tips'-?. A good theoretical developement may need tons of material; some of us are moderately experienced players, but I�m sure we are not big authorities,and a theory developed by us may be biased, somewhat primitive and far from exhaustive and water-proof. I can do something about it time to time, I suppose that other experienced players here can do something too: Matthew, Antoine, some others and, generally, everybody who visit TCVP can give us something interesting...

Well, I have tried this game briefly. I have to say it seems better than you can figure at first view. I may be influenced because I always rate good or excellent other progresive variants, but I feel this variant more nice to play.

Roberto Lavieri wrote on Sat, Jul 8, 2006 04:13 PM UTC:
Yes, Mr. Habu is the best Shogi player right now, and he plays Chess 'as hobby'; he has said he has not time to study Chess theory more than the basic things, and he practices Chess very eventually. But he has obtained in the last Tournament his second 'Chess International Master norm'. One more and he is going to be IM, an IM that only plays the game once in a while, without dedication to it. Remarkable, but, undoubtedly, his Shogi experience helps a lot.

This game is a classic. It is very difficult to master, due the extreme deepness regardless you can finish a game in very few moves. On purpose of other Italian things, (caugh, caugh), see the sports news.
