 By Peter  Aronson. Jumping Chess. (Updated!) Pieces capture by jumping. Board has extra edge squares making it 10x10. (10x10, Cells: 100) [All Comments] [Add Comment or Rating]

Jumping Chess originates the edge squares that Rococo uses two years later. Bishop captures like International Draughts diagonally and Rook like Turkish/Israeli draughts orthogonally. Except no plural captures, and in JC the line pieces slide any distance beforehand. But no displacement capture at all here. Jumping concepts are bandied about in 'ECV' a few times, but credit this improvement for the rim accessible only capturing.

JC may create too many defensive positions for most aesthetics.

JC year-2000 date of invention harkens to V. R. Parton's booklet 'My Games for 2000 a.d. and After' published 1972. There the CV "2000 AD" sources pieces for 30 years later great Rococo. Firsthand, Rococo is basically a derivative Ultima (1962).

( Contrariwise, Robert Abbott himself weighed in early Rococo comment that no need for border squares, just get rid of them. ) See next how Rococo draws on both Abbott and Parton. 20th century the chief variantists were Boyer, Parton, Betza and Dawson, but Dawson didn't bother with designing actual CVs.

The Rococo pieces straight out of Abbott's Ultima are Withdrawer, Immobilizer, Long Leaper, Chameleon. And the Rococo pieces straight out of 2000 A. D. are Ximaera and Swapper. Ximaera gets re-named Advancer. Finally, Rococo takes its own inventor's border squares from JC and adds that great novelty Cannon Pawn.

Perimeter-squared JC has little play, but Rococo, when adding its subvariants Push-Pull and Mirror, has the same number 10 rank approximately of near-form Ultima at Game Courier. And several ahead of them are a standard Chess form around hundred(s) years. Or combine play numbers of Ultima and Rococo and they are number 3. So arguably derived-form Rococo is a topmost world-class CV. Thanks to contribution of porous out-migration squares from selfsame JC.

After seven years, I am ready to concede that JUMPING CHESS was the best idea presented in the 100 Squares Chess Variant Contest. Not comfortable with the 'capture the King' victory condition, so I finally did something about it. Also replaced Knights with Nightriders and added some short range leapers.

Jumping Chess is not a bad game, the game play is very interesting, although it is undoubtely biased to defensive schemes if you want to have good chances of winning, but it is very strategic, perhaps much more than FIDE-Chess. If a player tries to play it using Michael Tal´s or Bobby Fischer´s styles, it is very possible it is going to be in disadvantage quickly. This game must be played a-la- Tigran Petrossian, for better possibilities.

Well, I can't agree with the 'poor' rating. I played a couple of games of Jumping Chess with Peter. One of these is posted as a Game Courier Log and the other is posted as a Zillions Saved Game (See also). I enjoyed the games. I found that the jumping feature added an entirely new dimension to both capture and checkmate. The restricted outside ranks and files provided both opportunity and danger (which I found out the hard way). <p>As far as uniqueness, that does not determine whether a game is good or not. As far as the Knight's character being somehow degraded, I'm not sure I understand the logic there: all the pieces have different capture properties. As far as any 'veredict' from the number of Game Courier Logs, that does not say much, except for the most popular games, Shogi and Fisher Random Chess. Jumping Chess is No. 8 in the 2nd Game Courier Tournament Preference Poll -- not too bad; it'll probably enter. <p>Jumping Chess also inspired me to invent Takeover Chess, which also won a contest. Again, I don't claim any special chess prowess, however, I did enjoy the game very much. Isn't that the point?

Jumping Chess is another contest winner (Aronson won several contests). This one is not recommended, mostly because generalized jumping eliminates the uniqueness Knight has. There are only two Game Courier log-scores the last one a year ago, indicating an apparent verdict. Besides, somewhere Aronson himself says jumping-chess concepts, or jumping pieces generally, were invented before. I did not bother to look that comment up, or jumping predecessors in Pritchard's 'Encyclopedia Chess Variants'. This set of rules is just one from a potentially infinite set of sets of game rules featuring jumping pieces. All that said, the board is important towards development of later Rococo. Also, jumping Pawn was a work-in-progress to its Cannon Pawn. With David Howe's contribution, they hit a home run with Rococo! Jumping Chess is a strike out.

Sorry, I should have been clearer. Subject to my April comment I think that the game is a good one, for being close to both Chess (as you say) and Draughts. My later suggestions were for additional variants alongside it. A further example of this would be for pieces jumped over to change sides instead of being removed, which would lose a little of the Chess and Draughts character but add something of Shogi and just a touch (in terms of immediacy) of Othello/Reversi.

Two further variants occur to me. One is to have Nightriders instead of Knights, so that my preferred capture would be more in accord with the normal move of that piece. Another is to allow a capture of any number of pieces in a straight line, though not necessarily adjacent, like a Queen in French Draughts.
