question about K/B/R/Q odds  Empty
PostSubject: question about K/B/R/Q odds    question about K/B/R/Q odds  EmptyThu Sep 23, 2021 2:55 pm

Hello,
I read in Ed's thread a significant amount of work and testing activity; which is actually interesting and entertaining (thanks for sharing!).
In addition, I am curious about any specific objective that may drive this testing?
For example, I wonder if the results would, at some point, provide a rule of thumb for a typical Elo-loss, scaled according to the chosen odds?
Cheers,
Eric

GM Larry Kaufman made playing odds games popular, see https://komodochess.com/store/pages.php?cmsid=17

Extending this to comps is just fun, no other particular value IMO.

Just experimenting...
Re-using your final standings, I get:
Code:
Knight odds      Pool    Pool    Pool
Engine           2700    2500    2300
Komodo Dragon 2  55.6    73.8    89.9
Stockfish 14     28.5    47.2    70.1
3500             -856    -926    -959  avg: -914

Bishop odds      Pool    Pool    Pool
Engine           2700    2500    2300
Komodo Dragon 2  47.1    67.6    81.8
Stockfish 14     14.5    31.3    51.2
3500             -941   -1004   -1081  avg: -1009

Rook odds        Pool    Pool    Pool
Engine           2700    2500    2300
Komodo Dragon 2  25.5    52.9    73.2
Stockfish 14     18.0    41.1    64.0
3500            -1022   -1021   -1064  avg: -1036
Where I assumed 3500 Elo for the pool Komodo D2/SF14; then averaged the %performance from both and translated this into an Elo perf. I then displayed the Elo loss.
I observe a not so bad consistency of the Elo loss across the opponents' pools.
Queen odds would need KD2 and SF14 to face weaker pools, otherwise the performance is too low to translate into and Elo perf.
Cheers...
