The Immortal Chess Problem by Conrad Bayer (1851) – Mate in 9 Moves!

The 1st move will be done after 22 seconds. This one is not made for beginners; it would even give grandmasters a hard time … … but it is very nice to watch anyway. But you may also analyze it in reverse if you like.

  1. … and here comes the REVALORIZATION of the puuzle : put a white knight on e4 and a black pawn on g7 and you have an "immortal chess problem" with mate in 10 moves , beginning with 1.Nxf6+ gxf6 and than the 9 moves from Konrad Meyer. But if anyone want to see a realy hard puzzle have a look at this side here at youtube :

  3. I like the idea to put a knight onto e4 and a pawn on g7, indeed this would extend the problem for two half-moves. Still checking on your problem but let's not forget that back then in 1851 there was no chess engine available for checking around.

  4. Honestly, this does not convince me at all. How do you want to prove that your analysis (or your engine's) is correct? Secondly, the 50 moves rule should also count for compositions.

  5. However, I should add that taking pieces out or giving a check by the first move was/is a bit frowned upon. Maybe that's why Bayer didn't put an extra knight and pawn onto the board.

  6. … with the best chessprograms like as Houdini 3 or Rybka 4 you can't solve my chessproblem : for example see move 5.Kc3! , because nowadays CHESSPROGRAMS PLAY ALL THE WRONG MOVE 5.Ka3 , but this field is necessary for the white Queen in move 9.Qa3+! To understand this you need to have a look at the 7-pieces-ENDGAME-TABLEBASES (all moves here are 100% correct and after my 2 beginning moves 1.Rxa4 Qxa4 2.Bxa4 Bxa4+ you are IN THESE TABLEBASES) A 50 moves rule would restrict the beauty of chess !

  7. I think it's ok to ignore the 50 moves rule when looking for "moremovers" (a mild chess variant so to speak) but I wonder if 5.Kc3 is really stronger. 5.Ka3 wins a piece and that's why engines prefer that one, e.g. 5.Ka3 Ne7 6.Qa8+ Kd7 7.Qf3 Rd4 8.Qh3+ Kc6 9.Qe6+ Kb7 10.Qxe7+ Rd7 and 11. … Bc6. Are you to 100% sure that white can't break the blockage on b7?

  8. to chessrookies : I can convince you ! Please go to the following side in internet :
    ( attention : with a POINT between "chess" and "ok" )
    put in for white : Ka3 – Qc5 – b6 and put in for black : Kb7 – Rd7 – Bc6
    and push the Evaluate-Button
    … and you see it is a draw in the Endgame Nalimov Tablebases …

  9. Ok, I checked. According to that database (?) the evaluation of your position is correct but on the other hand: White: Kb4, Pb6, Qa1; Black: Kc8, Rd7, Bc6 should be mate in 28 moves says the tablebase. Question would be how that tablebase works. Also databases can contain mistakes, e.g. where does that data come from?

  10. Ok, I must correct the position, it is not relevant. The king should be e.g. on b3 and then the tablebase says it's a draw. I must check a little further…

  11. Alright let's assume that black has a fortress. I checked white Kc4, Pb6, Qa7; black: Kc8, Bc6, Rd7: 1. Qa6+ Kb8 (forced acc. to tb.) 2.Kc5 Rd5+!! 3.Kxc6? Rc5+! draw (either stalemate or perpetual). If white doesn't capture on c6, then he can never support Pb6, etc. -> also draw. For a 500-mover there would be of course much more to check. I am too busy with other things though. Anyway, right or wrong, pretty interesting your stuff. However I am mainly (but not only) interested in human chess.

  12. Yes, your position ( White:Kb4-Pb6-Qa1 and Black:Kc8-Rd7-Bc6) is mate in 28 , but with the best moves of both sides your position never appears in the trees of my chessproblem, because after the first 2 moves of my chessproblem the 7-pieces-endgame-tablebases is already announcing "mate in 549 moves". All trees ( with 6! pieces ) are completely generated since over 10 years and everybody can generate these software ( less than 1000 GB ) for himself to see that he get the same results as Namilov.

  13. Indeed, by mistake I replied to myself instead of replying to you. I think that black's fortress might be solid (see comment below).
