Arasan test suite - draft version

Posted: Wed Jun 19, 2019 6:12 pm

Over the past several months, I have gone through the current Arasan test suite and removed some positions that seem too easy, and also added a bunch that are interesting and/or harder. Some of the latter have been posted here, but some have not. I've verified all the positions as best I can using multi-pv analysis. In some cases there is more than one good move, but the given bm scores significantly higher than other moves.

Current file is here:

https://www.arasanchess.org/arasan21-beta.epd

These are sort of in difficulty order: the ones towards the end of the set are generally more difficult.

I'd be interested in any feedback/corrections. I used Stockfish for verification, but results from other engines would be interesting.

There are several duplicate positions:

I ran the new positions with Stockfish_19060914 (6*4GHz), first column is 10 seconds per move and second column is 20 seconds per move.
The list is sorted on column1 then column2.
80 positions seem not so hard (for SF).

Rcf1 is best here I think. I don't see another equally good move: next best is Bf3 it seems.

Over the past several months, I have gone through the current Arasan test suite and removed some positions that seem too easy, and also added a bunch that are interesting and/or harder. Some of the latter have been posted here, but some have not. I've verified all the positions as best I can using multi-pv analysis. In some cases there is more than one good move, but the given bm scores significantly higher than other moves.

Current file is here:

https://www.arasanchess.org/arasan21-beta.epd

These are sort of in difficulty order: the ones towards the end of the set are generally more difficult.

I'd be interested in any feedback/corrections. I used Stockfish for verification, but results from other engines would be interesting.

Hi Jon,

Just FYI,

Line 174 r1b1k2r/1p1pppb1/p5pp/3P4/q2p1B2/3P1Q2/PPP2PPP/R3R1K1 w kq - bm Rxe7; c0 "McBrain test position, posted by Michael B";

was from line 7 on http://www.arasanchess.org/arasan18.epd

r1b1k2r/1p1pppb1/p5pp/3P4/q2p1B2/3P1Q2/PPP2PPP/R3R1K1 w kq - bm Rxe7+; id "arasan18.7"; c0 "Svidler-Carlsen, Longyearbyen 2006";

Great position btw, , so I am not too surprised it got regurgitated.

Yeah, not good. Too much LMR?

Cfish-dev finds Rxe7 in about 3.5 minutes---using one thread. Note that Rxe7 is move 42 (of 43 in the move list) when its finally recognized as best:

I removed positions found in less than 10 seconds, 2 times (and I hold all the AMs solutions).
It left 71 positions.
I ran this positions with the latest SF ( Stockfish_19062016 ) , 1 minute per position , 6*4 GHz.
Still 36 positions, not found each time under 1 minute.
