Chess variant tournament: Makruk (without endgame counting)

[enhorning]

Standings after the first cycle (out of 5), the 30 games starting with 1. Nd2:

Code: Select all

Cross table, sorted by score percentage, Buchholz, SB

                              Bi Ne Sj Ha Fa Fa
 1. Bilis v0.14               ## 10 11 11 1= 11   85%   8.5 ( 43.0,  33.5)
 2. NebiyuChess_1.45          01 ## 1= 1= 11 11   80%   8.0 ( 44.0,  31.8)

 5. Fairy-Max 4.8S            0= 00 0= == ## ==   30%   3.0 ( 54.0,  12.8)
 6. Fairy-Max 4.8S+           00 00 01 == == ##   30%   3.0 ( 54.0,  10.5)

Clearly two tiers of program... but seems quite close between the top two, and between the lower four.

I've installed all the programs - there will be six participants:

Bilis 0.14
Fairy-Max 4.8S
Fairy-Max 4.8S+ (aka MateMax, has extra Makruk endgame knowledge)
HaChu 0.17
Nebiyu 1.45
Sjaak 524

Time control will be 40 moves in 20 minutes, repeating, and hash will be 128 MB. The tournament will be a 10-fold round-robin, so 50 games / program, 150 games in total, with each pairing playing both sides of the following five openings (suggested by running the various programs for a long time from the starting position):

1. Nd2
1. Ne2
1. Kc2
1. c4
1. Mf2

The super-blitz tournament I ran to test things went mostly smoothly - there was one loss due to an illegal move:

... move 93 looks weird - surely that should be a6=M ?

Also, FairyMax / MateMax still sometimes get stuck thinking for too long, and lost a couple of games on time. I also had some Winboard crashes when starting up new games (old game finished, written to the pgn, and new game marked with a * in the trn-file, but WB still displaying the final position from the old game).

Results from the super-blitz (40/1) test tournament:

... so, looks like we're in for quite a close battle between Nebiyu and Bilis.

Going to start the tournament proper now!

Thanks for finally running the tourney. BTW do you accept engine update?

Sure, but it has better be soon then, as the tournament won't last that long; these games are finishing at quite a pace - almost done with the games of the second cycle while I was asleep.

[Daniel Shawul]

No he does not! Ferd you have got to loose for once

Looks unlikely even with no update to Bilis

In Makruk, is the KNQ-K endgame generally won or drawn? I've seen programs win it (e.g. the earlier posted game by MateMax, or just now, a game by Nebiyu - Sjaak, pgn link will be in next post), but that might have been because the King was already cornered. Bilis tried to win it against Fairy-Max in this game, but could not manage it, one of the few draws it has allowed against the tier-2 programs (EDIT: I just had a look at the other game it drew against tier-2 programs, against Sjaak, and it was again a KNQ-K endgame - so both its draws were in this endgame... either it need to learn to win it, or evaluate it lower):

... seems it has an occasional problem when promoting pawns.

Bilis won one of the games in the top match, and drew the other, earning itself a small gap ahead of Nebiyu.

Bilis tried to win it against Fairy-Max in this game, but could not manage it, one of the few draws it has allowed against the tier-2 programs

If I set Nebiyu to search at a point a bit after the reduction to 5P, when the black king is as near the a8 corner as it gets, Nebiyu fairly quickly sees a forced win. So, seems this is indeed a weakness in Bilis.

Sjaak just had a forfeit by illegal move, ignoring that it was in check:

In cycle 3, Nebiyu closed the gap to Bilis a lot by winning both games between them. That means it's +3 =1 -2 for Nebiyu, so it's ahead in games between the two of them, but gives away more draws to the tier 2 programs (6 draws for Nebiyu versus 3 for Bilis).

No he does not! Ferd you have got to loose for once

Looks unlikely even with no update to Bilis

In Makruk, is the KNQ-K endgame generally won or drawn? I've seen programs win it (e.g. the earlier posted game by MateMax, or just now, a game by Nebiyu - Sjaak, pgn link will be in next post), but that might have been because the King was already cornered. Bilis tried to win it against Fairy-Max in this game, but could not manage it, one of the few draws it has allowed against the tier-2 programs (EDIT: I just had a look at the other game it drew against tier-2 programs, against Sjaak, and it was again a KNQ-K endgame - so both its draws were in this endgame... either it need to learn to win it, or evaluate it lower):
