Message #2255 in the 'Chess Variants' Yahoo group described 'a game with no name' by Derek Nalls that was, in retrospect, merely a flawed precursor of the game that became Optimized Chess by OmegaMan [my pen name for games I invent but do not recommend playing]. So, thank you but I doubt it is worthy of mention.
OK, I have been doing some thinking about Capablanca chess variants. As discussed before, there are some 126,000 possible Capablanca opening setups, where the bishops are on opposite colors, and where the queen is to the left of the queen. However, looking at all of the Capablanca opening setups which have actually been proposed, I observe that:
RANBQKBNMR Aberg RMNMQKBNAR Carrera RNBMQKABNR Bird RNBAQKMBNR Capa 1 (Suffers from 1.Mh3 mating threat) RNABQKBMNR Capa 2 RBQNKMNABR Grotesque RBNMQKARBN Univers RBQNKANMBR Landorean RNBQKMABNR Embassy RQNBAKBNMR Schoolbook NRMBQKBARN Optimized MRNBQKBNRA Paulovich 1 link ARNBQKBNRM Paulovich 2 link QRNBKABNRM Paulovich 3 RNMBQKBANR Nalls linkAll of these, should I note, are perfectly playable, with the exception of Capa 1, and all of these have not had their openings explored nearly enough. Doing some slightly creative math, that leaves us with 56 possible starting setups. Here are some interesting ones, with names that I propose for them: RNBQKAMBNR Consulate RNQBKMBANR Finesse RNQBKABNMR Notebook QRNBAKBNRM Closebook QRNBKABNRM BlackbookHere are three openings setups that are unplayable: RNBQAKMBNR 1. Mh3 mating threat QRNBMKBNRA 1. Md3 mating threat QRNBKMBNRA 1. Mh3 mating threatNow, if instead of a R+N and B+N piece, we add two colorbound Camel + Bishop (Sage) pieces, and have an 8x10 board, we have 36,000 total possible opening setups (Sages and Bishops on opposite colors, queen to the left of the king). Of those, all of 12 meet the requirements above: 1. SRNBQKBNRS 2. RSNBQKBNSR 3. RNSBQKBSNR 4. RNBSQKSBNR 5. SRBNQKNBRS 6. RSBNQKNBSR 7. RBSNQKNSBR 8. RBNSQKSNBR 9. NRSBQKBSNR 10. NRBSQKSBRN 11. BRSNQKNSRB 12. BRNSQKSNRBOf these 12 setups, I find 1, 4, and 12 the most interesting. No, I'm not proposing a new variant. I first need to fully explore the opening in Schoolbook. :) |
