💙💛Thank you Jerry for sharing this gem. I had no idea that there's a website where I could play this variant of chess. So far - enjoying it a lot. Even playing against computer is much more fun than the regular chess, because the pieces are so tricky and combinations sometimes are just unpredictable. Also - big thanks to you and your work. I've been watching and enjoying your videos for many years already. Happy to see you still posting and also enjoying the game.
Easily my favorite videos from your channel are your commentaries, your variant games, and you analysis of master games. Thank you for all the fun and education!
absolutely love the concept of archbishop and chancellor. seems like the value of the chancellor is about the same as a queen, similar to the relationship between knight and bishop. And archbishop is around a 6-7 (so better than a rook but not as valuable as the queen). Would love to see more!
I think the queen is still the most valuable just because it covers way more squares. I also suppose that a bishop would be more valuable than a knight on a 10x8, as it can go from one side to the other in 2 moves max while itqy take a knight up to 4 moves. Playing on both sides of the board seems just way easier than it be on an 8x8, with bishop vs. knight
thank you for the video! i'd be really excited for more capablanca chess videos, or for more variant videos in general such as grand chess or other things on pychess. either way i have loved your videos over the years!
I enjoy playing Gothic (Trice) Chess online, which is similar, but with a different arrangement of pieces on the back rank. I really like the very logical extension the new pieces bring, given that a Queen is essentially just a Rook + Bishop already.
Do you agree Capablanca's prediction will come to pass at some point, and these more complex variations will increase in popularity, maybe even surpassing regular chess some day?
I think they've gone as high as they could (since computers and internet made it easy for interested players to pair up, eliminating the need for custom chess sets etc.) for 99.99% players classic chess is as fun as it ever was, they don't experience "draw death" and don't memorize openings up to move 30. chess variants have ALWAYS existed. it's not like the classic one prevailed just because. it stood the test of time against countless competitors. it's like regular sex :) variants are there to spice things up now and then, SOME may swear by those,, but the default way won't go anywhere.
also note how the trend has notably shifted. these days there's fewer "radical" variants with fantastic pieces, non-standard board sizes etc.(like Caoablanca chess). 960, which once seemed quite conservative (apart from the initial setup, all rules are pretty much preserved) became actually one of the more radical deviations in the current landscape. the variants people consider now are more like the ones proposed by Kramnik, tested with Alpha Zero: all the same but no castling... all the same but pawns can always move by 2 squares,... this sort of thing: very modest (if impactful) alterations of the classical ruleset.
@@vibovitold yep, agree, and I think that’s for good. Smart men add, wise men subtract. 960 looks to be the closest solution to the openings theory memoization problem though. No castling is just not enough. However I’d still simplify a few things in 960 to make it more practical in attempt to make it more widely used. E.g. fix rooks and kings in place to make castling obvious and only shuffle bishops, knights, queens.
Have you been playing any other variant? I would like to see you making videos on other variants, your commentaries are very insightful and your playlist on beginner to master was superb!!
I would like to see such chess variants gain more traction especially for computer chess as computers will draw so many games it's as if the game isn't complicated enough for them to struggle (although of course they do, otherwise they wouldn't lose)
come to think of it that might be the first time I've actually seen a game of Capablanca chess played. Seen the rules explained .. but actually it makes much more sense in action. Was surprisingly enjoyable to watch, and there is this sense of space, which is quite interesting.
intriguing. i found this on wiki as a basic orientation point. at least it gives a rough idea what to trade and what not. pawn 1 knight 3 bishop 3.5 (+0.5 for the bishop pair) rook 5 archbishop 8.75 chancellor 9 queen 9.5
Thank you for the video. I have the chess set and board from House of Staunton. I haven't tried to play the game. Years ago I asked a chess-playing friend if he would play Musketeer chess, but he said no because he thought chess was hard enough for him.
If you plan on playing more pychess variants I'd recommend Shogun Chess. It introduces the fairy pieces in a way I haven't seen elsewhere: the initial setup is just like regular chess, but you have the option of promoting pieces if you move them into the final three ranks, much like in shogi. The game feels a lot like regular chess despite all the new possibilities, it's kind of the best of both worlds.
maybe 960 Fischer Random could also fix top level draw occurrence issue with traditional chess? i feel like 960 looks a bit more standard and could possibly attract more of the general chess population. To support my statement, right now there is 960 world championship with top level players competing, including Carlsen, Nakamura, So, Nepo, not to mention the other GMs
@Jerry : I thought up two pieces called 1. The Prince and 2. The Princess !!!! They stand next to the Queen and King !!!! And can move up to three squares in any direction !!!! The board would expand accordingly , with 10 pawns !!!! .....................
The bot that he is playing against in the video, Fairy Stockfish, is one of the strongest variant chess engines in the world. Its level 5, so it was easier to beat, but Fairy Stockfish level 8 would possibly surpass the best humans at capablanca chess. Its at the point where it even has its own neural networks (NNUE) for each of the variants it supports. Fairy Stockfish 14 combined with its neural network might surpass AlphaZero. I would really hope to see a matchup of AlphaZero and Fairy Stockfish like that, but I doubt it will happen.
@@clausable6328 Obviously the machines play at a much higher level than any human mind. I would still be interested to watch, even if I can't figure out the intent behind every move.
i've always been so excited at the idea of top players playing OTB Grand Chess (10x10 variant similar to capablanca). I know it's not the same as capablanca chess but both would be cool on some level!
@@vibovitold chess commentators got along just fine for many years without engines and some still do today. It’s actually more interesting when everyone watching has to figure out who has the advantage
Computer played bc7 as you were able to pick up a free pawn on c5 as recapture leads to queen check and then pick up the bishop on a5. Why the computer played ba5 in the first place is the bigger mystery hahah
Since 12:17 to 14:02 he could’ve taken the rook with his Archbishop on H8. Then stock fish would’ve taken back with his archbishop and then you take the undefended night on H7
Would be really great if variants were played like variants and thought of as variants. Even in 960 people try a weird 'English' or whatever opening there is. Trying to turn the variant back into normal chess, which I suppose what the whole thing the variant tried to stop.
Thank you for showcasing this site. Potentially interesting to have an AI to try and play chess variants against. Whatever happened to Omega Chess? That crossed my radar some years ago, but did not buy a board while they made them, sadly. Wish I had for the different pieces and board, even if it didn't exactly last as its own game.
If you type just 'pychess' in the searchbar you will find it immediately, it takes u like 5 seconds. You can find the searchbar on top of your internet browser.

Hello Jerry I am a Casual Chess Player but Have Accumulated More Than 500 Wins Against THe A.i. on Chess Pro on my phone At The Hardest Level With No Time Limits, How Could i Send u These Games 4 Analyses Maybe ????
@@Aesculus1989 Then the queen should be worth 8 points too. I haven't played yet but I'd guess 8-9 and 7 are more appropriate. Pieces that are part bishop benefit a lot from their counterpart by being able to visit both colors, so should get an extra point over addition. I'd guess there's some similar synergy for the chancellor as well
@@dizzybananas conventional chess has queens worth 9, Rooks 5, Bishops 3 and knights 3. I was trying to put it into that framework. I have also seen it argued that bishops are worth 3.5. However, I agree on the ability to switch colors being a major advantage and the inability of a bishop to do so is probably what limits them to only being worth 3 points in international chess. So, I agree that 7 is probably a better value than 6.
Gothic chess (or Trice's Chess) resolves the I-pawn weakness by placing the Queen on the D file, Chancellor on the E file, and Archbishop on the G file. That way, all pawns are protected by at least one piece at the start of the game. If select "Alternate Start" when creating a game on PyChess, you can select Gothic chess and other variants (e.g., Bird's chess).
@@KralleZ7 But Bxb6 Axb6 is good for White. c5 is a good pawn that controls the center, and winning it also makes Black's d-pawn permanently backward. Totally worth trading bishops!
It takes too long to get some action. Also the regular knights are slow and decrease in value way more than the regular bishops - pieces which can go across the 10x10 board in a flash
Seems Capa had a stake at a carpentry making chess boards. Otherwise how would you explain a 10x8 board? :$ On a serious note, converting one bishop and knight to 1 kbishop and knook sounds like a more organic idea.
i just checked, and they apparently do have that on pychess! they also have capablanca + 960, and capablanca + 960 + crazyhouse, and other variants with knightrook and bishoprook (grand chess and s-chess/seirawan chess).
How? fxg6 is met with Axg6 (A= Archbishop) after that f7 is double protected by queen and archbishop so that Qxf6+ can be blocked by Af7 or Qf7. fxg6 can also be met with ...Qxg6 covering f6 directly. Or am I lost somewhere?
@@D1A6NBA I think the idea is that after Qxg6 White would take the rook. So I guess Axg6 and Af7 would have to be played, but then White brings a rook to the f file and it is probably game over
Mind bending and fun to watch--enjoyed this one, Jerry.
