Thanks, I did not see version 2.0.1 I will try to find it, Sorry. I downloaded it from here ==> https://github.com/Matthies/RubiChess/releases/tag/2.1

I played only a single game of RubiChess without a knight against Fruit2.2.1 but RubiChess won

I wonder if Dragon is better than RubiChess against engines with knight odd conditions.

Very interesting, but it is only one game, I wonder how many games it will win if it plays the same amount of games that Komodo played ?

Dragon 2 lost badly giving knight odds to Benjamin 1.0 (2698 CCRL Rapid), +27 -92 =5 (-202 elo) in Rapid (15' + 10"). I've noted before here that this Ed Shroder program is unusually good at playing receiving knight odds, so I shouldn't be surprised. It is really much closer to a human substitute than other engines of the same rating. Good work, Ed! Against Arasan 14.1 (2651 CCRL Rapid), Dragon 2 is currently leading by 31 to 22 with 7 draws at knight odds, match continuing. So overall it seems to perform around 2680 or so against engines other than Benjamin at knight odds, but only around 2500 against Benjamin.
Regarding RubiChess, I'm not familiar with it, but is there any particular reason to expect it to perform better giving knight odds than other higher rated engines? Were threads set to 1 for both engines in the above game (I think Fruit 2.2.1 is only single thread)?

I gave RubiChess 3 threads and not one thread in the games that I did but the reasons I expected RubiChess to perform better are:
1)It is number 4 in the CCRL list
https://ccrl.chessdom.com/ccrl/4040/

2)earlier I tested it with bigger handicap (in a queen handicap tournament) when I included also stockfish13 and I found that stockfish was clearly weak in these conditions and RubiChess simply mated faster in pair of games against stockfish.
RubiChess was also the only engine that could get points against with queen handicap against Dreamer 0.3.0 64-bit in my tests
see
http://talkchess.com/forum3/viewtopic.php?f=6&t=77257

3)I decided that I do not like Stockfish because of the big failure of it to mate faster with an advantage of a queen.
Number 2 and 3 are commercial programs so I guess that the best candidate of engines that are not commercial is simply RubiChess that is number 4.

Very interesting, but it is only one game, I wonder how many games it will win if it plays the same amount of games that Komodo played ?

Dragon 2 lost badly giving knight odds to Benjamin 1.0 (2698 CCRL Rapid), +27 -92 =5 (-202 elo) in Rapid (15' + 10"). I've noted before here that this Ed Shroder program is unusually good at playing receiving knight odds, so I shouldn't be surprised. It is really much closer to a human substitute than other engines of the same rating. Good work, Ed! Against Arasan 14.1 (2651 CCRL Rapid), Dragon 2 is currently leading by 31 to 22 with 7 draws at knight odds, match continuing. So overall it seems to perform around 2680 or so against engines other than Benjamin at knight odds, but only around 2500 against Benjamin.
Regarding RubiChess, I'm not familiar with it, but is there any particular reason to expect it to perform better giving knight odds than other higher rated engines? Were threads set to 1 for both engines in the above game (I think Fruit 2.2.1 is only single thread)?

I gave RubiChess 3 threads and not one thread in the games that I did but the reasons I expected RubiChess to perform better are:
1)It is number 4 in the CCRL list
https://ccrl.chessdom.com/ccrl/4040/

2)earlier I tested it with bigger handicap (in a queen handicap tournament) when I included also stockfish13 and I found that stockfish was clearly weak in these conditions and RubiChess simply mated faster in pair of games against stockfish.
RubiChess was also the only engine that could get points against with queen handicap against Dreamer 0.3.0 64-bit in my tests
see
http://talkchess.com/forum3/viewtopic.php?f=6&t=77257

3)I decided that I do not like Stockfish because of the big failure of it to mate faster with an advantage of a queen.
Number 2 and 3 are commercial programs so I guess that the best candidate of engines that are not commercial is simply RubiChess that is number 4.

Here is "RubiChess 2.1 NN-cf8c5 (bmi2) with 3 cores. I am guessing that the next move was going to be RxB followed by d2!

I played only a single game of RubiChess without a knight against Fruit2.2.1 but RubiChess won

I wonder if Dragon is better than RubiChess against engines with knight odd conditions.

Very interesting, but it is only one game, I wonder how many games it will win if it plays the same amount of games that Komodo played ?

Dragon 2 lost badly giving knight odds to Benjamin 1.0 (2698 CCRL Rapid), +27 -92 =5 (-202 elo) in Rapid (15' + 10"). I've noted before here that this Ed Shroder program is unusually good at playing receiving knight odds, so I shouldn't be surprised. It is really much closer to a human substitute than other engines of the same rating. Good work, Ed! Against Arasan 14.1 (2651 CCRL Rapid), Dragon 2 is currently leading by 31 to 22 with 7 draws at knight odds, match continuing. So overall it seems to perform around 2680 or so against engines other than Benjamin at knight odds, but only around 2500 against Benjamin.
Regarding RubiChess, I'm not familiar with it, but is there any particular reason to expect it to perform better giving knight odds than other higher rated engines? Were threads set to 1 for both engines in the above game (I think Fruit 2.2.1 is only single thread)?

I gave RubiChess 3 threads and not one thread in the games that I did but the reasons I expected RubiChess to perform better are:
1)It is number 4 in the CCRL list
https://ccrl.chessdom.com/ccrl/4040/

2)earlier I tested it with bigger handicap (in a queen handicap tournament) when I included also stockfish13 and I found that stockfish was clearly weak in these conditions and RubiChess simply mated faster in pair of games against stockfish.
RubiChess was also the only engine that could get points against with queen handicap against Dreamer 0.3.0 64-bit in my tests
see
http://talkchess.com/forum3/viewtopic.php?f=6&t=77257

3)I decided that I do not like Stockfish because of the big failure of it to mate faster with an advantage of a queen.
Number 2 and 3 are commercial programs so I guess that the best candidate of engines that are not commercial is simply RubiChess that is number 4.

OK, so your test was with three threads vs. 1 for Fruit, while mine was one thread for each, same as chessqueen. Perhaps I'll try Stockfish and RubiChess in the same way as I tested Dragon in the coming days. Probably we should focus on Benjamin as the odds-receiver, it seems to have a much more human-like ability to utilize the knight handicap than other engines of similar rating, and it's a free download. I also checked out Lc0 (recent version, cpu-version) setting a low nps to get it down around the strength of these 2700 rated engines, and it acts about like Benjamin in that with a setting of 1.5 nodes per second it is about even with Benjamin and also beats Dragon 2 with knight odds by a similar margin as Benjamin. So we might as well use Benjamin, so as to avoid having to deal with what version and nps setting of Lc0cpu to use. I wouldn't make any assumptions comparing queen odds with knight odds; Stockfish and Dragon and perhaps other NNUE engines fully or partially disable NNUE when one side is up much more than a knight, but with knight odds NNUE is still generally used I think. As a chessplayer I consider knight odds chess to still be chess, but queen odds chess is just something to use to teach or evaluate novices, it's not a meaningful test of chess strength for the odds-giver.

knight odd default stockfish13 lost against fruit in the single fast game that I did

I tried latest developement version(contempt 100) and it scored better so I will try also latest stockfish


I tried one fast game with stockfish13 and Fruit won easily

I change the contempt of stockfish13 to 100.

I do not understand 8.Ba3 of Stockfish and it seems stockfish13 does not know not to trade piece when it has less of material.

Latest developement version of stockfish performed better and it could win Fruit even at longer time control
then the time control that I tried earlier(20 minutes/40 moves)

I did not play many games with it.

Latest developement version of stockfish performed better and it could win Fruit even at longer time control
then the time control that I tried earlier(20 minutes/40 moves)

I did not play many games with it.

I was also wondering if the Bishop is an equal handicap to the Knight or does it benefit the engine better against a human GM ?

I was also wondering if the Bishop is an equal handicap to the Knight or does it benefit the engine better against a human GM ? .Here is Stockfish giving the c1 Bishop , it is hard to predict if a Knight odds or Bishop odds benefit a human GM more or the Engine. I would like to hear from Mr. Larry Kaufman.
