A.Buchanan: In what sense are the two promotions “konsekutive”? (2021-02-24)
James Malcom: Andrew, it's much less a keyword for consecutive promotions as it is a catch-all for all problems with 2 promotions in them. (2021-02-24)
Olaf Jenkner: "konsekutive" means one promotion after the other, not two promotions in two variations.
Of course in helpmate this doesn't make much sense. (2021-02-24)
A.Buchanan: Hi thanks for this. Let's take a step back. I counted *85* non-fairy keywords which refer to promotion or umwandlung in either name or description! There must be other relevant ones with no descriptions today. A keyword has no value to us until it is accurately populated (a small percentage of false positives and negatives). And it requires substantial work to populate. There is also a lot of overlaps and gaps still, which are harder to distinguish because of the number of keywords and the vagueness of both their intended descriptions and usage. I also want to make as precise as possible keyword definitions and to align with actual usage, so that they can be populated automatically by PDB as easily as possible, and so that different curators can populate data harmoniously. So less is more, and then we can fill any gaps that remain. The data doesn't have to be perfect right off, but we should have a path for convergence over time.

"Promotion" can be the catch-all vanilla keyword to track promotions where the promoted officer can be identified, e.g. promotion(Sd) or promotion(x2 Sd). Separate different phases by comma, as usual. “Consecutive promotions” can then return to its intended usage as a thematic keyword identifying a run of promotions as close together as possible. The count shifts to the parameter field rather than part of the keyword itself e.g. not “consecutive promotions 4(stst)" but “consecutive promotion(x4 sstt)”, to reduce the over-supply of keywords, and to allow more selective filtering. Comments welcome. (2021-02-26)

19.099 (Baumann) Zuerst soll der sLäufer in die gegenüberliegende Ecke gelenkt und dort blockiert werden, damit Weiß seinen Mattkäfig bauen kann.

Tries:
1. e5 Rb1?
2. e4 Rb5
3.axb5 is surprisingly too slow!

1. e5 Ra3? fails because of the white king standing around in the way.
1. e5 Rd1? also fails because of the white king standing around in the way.
Mirko Degenkolbe: Dies ist das zuglängste korrekte orthodoxe Hilfsmatt, in dem Weiß im ersten Zuge die Rochade ausführt. (2020-10-03)
