It is possible to beat stockfish with queen odds

[Uri Blass]

I used time control of 40 seconds for 40 moves and got the following pgn
2048 mbytes for every engine.
Stockfish won the match 19-1 becuase it usually won as black but in this game stockfish lost.
I used opening book with all possible 20 legal moves of white.

Here is another draw from a second tournament that I played.
It seems that stockfish had a bad time management.

I am really surprised that your 'gut' feeling from a previous thread this time was right
and SF even is able to lose when receiving Q odds, even if it is known that it misstreats high odds.

It seems to boil down to some much too risky time management though, which you have
just mentioned for the second game, but it looks like it is immanent.

BTW why did you have Wasp 4T vs. SF 1T?

Are you able to get such a result with an inc game too? (may be sth like 0.20 + 0.5?)

Code: Select all

Explanations:
M# = move number	
WM = White move	
WE = White Eval	
WD = White Eval	
WT = White time	
WDA = White depth average	
WTS = White time sum	
WTT% =White time total percentage	
BM = Black move	
BE = Black Eval	
BD = Black Eval	
BT = Black time	
BDA = Black depth average	
BTS = Black time sum	
BTT% = Black time total percentage	

(depth removed for mate scores, because those numbers are incomparable)

The reason to have 4 threads for Wasp is that I wanted to see if it is possible to beat stockfish with 1 core in that time control.
see the following thread(I sometimes have problem to post here and get forbidden error so I post there)
https://prodeo.actieforum.com/t545-how- ... me-control

I found that Wasp with 4 threads could also beat stockfish with 1 core at 1+1 time control.
When I tried 1 thread Wasp won all 20 games but maybe Wasp missed a draw and I am not sure.

See the following game:
After 66.Nc4 at least black need to sacrifice a piece to try to win if white does not let him to trade pieces like wasp.

I used time control of 40 seconds for 40 moves and got the following pgn
2048 mbytes for every engine.
Stockfish won the match 19-1 becuase it usually won as black but in this game stockfish lost.
I used opening book with all possible 20 legal moves of white.

Very nice discovery Uri! I could only check with and old Toga from 2013 on even older hardware, but it seems in this game 33... Nc8 is a blunder from which there is no recovering. Even Toga sees this after 98 seconds and there is a massive Fail High. Toga does not get more than 12 plies deep here... After 33...Nc8??

I see I picked a pgn from a post on Ed's site, so the example is valid, but it was a different game that Uri showed there: https://prodeo.actieforum.com/t545-how- ... me-control
