Henrik Juel: Missing Joke keyword, I guess (2020-05-11)
A.Buchanan: Curious that retro a7-a8=sT discomforts the animation still - maybe you should report to Gerd? (I trouble him with enough stuff already - don't want to be the only one emailing him! :-) (2020-05-11)
A.Buchanan: Maybe +sBe7f7 to refute R. ... e8=sK/fxe8=sK :-) Note this "cook" is actually prevented in the original. (2020-05-11)
A.Buchanan: Oops and a more major cook R: 1. Se8/g8-f6+ (2020-05-11)
James Malcom: This problem was only half-finished before I fell asleep. It’s fixed now. (2020-05-11)
A.Buchanan: Great! You could save another piece I think -sLg6, -sBf7, + sDf7. This also removes the obtrusive promotion (2020-05-11)
James Malcom: Yes, that is true. Position edited. (2020-05-11)
James Malcom: I see nothing wrong with fiddling if it improves economy. (2020-05-11)
A.Buchanan: If promotion to Bl unit is allowed, can’t Bl just have played e8xd7+ or g8xh7+? Can replace bPd7 with bR but eliminating bPh7 is more complicated. Need +wPh7 +bPg6h6. And also bRb7 to prevent discovered check by bPc8 prior to e7-e8=bK. I think that’s watertight now! :-) (2020-10-13)
A.Buchanan: The issue is that there are two or three levels of Bl promotion joke: this problem relies on the "basic" joke where black officers can be created. But where's the line to stop us promoting to Bl pawn or king? If we go that far, then a position like this 2kr3K/1r1r1qrR/7p/8/8/8/8/8 is required. Oh dear: sorry to have brought it up :( (2020-10-13)
