Four (1,2,3,4) fixed ply games against SF12

[Mike Sherwin]

Every once in a while I play SF a serious game to see if I can still play chess. My record over the years is 4 losses and 4 draws. And in queen knight odds playing black my record is 1 win and 2 draws. I gave up after SF10 came out because it just seemed to be a losing battle. Today I wanted to see how SF12 NNUE played if given limited depth. I played 4 games starting at a fixed depth of 1 ply to 4 ply. I managed to win all 4 games. That does not say much but it was fun. Tomorrow I'll try 5, 6, 7 ... ply. Here are the games.

Great to see that someone else is actually playing these machines as well! Did you use an opening book or „just“ pure Stockfisch? I‘ll try it with limit depth as well, but doubt I’ll even beat 1.

[mwyoung]

Every once in a while I play SF a serious game to see if I can still play chess. My record over the years is 4 losses and 4 draws. And in queen knight odds playing black my record is 1 win and 2 draws. I gave up after SF10 came out because it just seemed to be a losing battle. Today I wanted to see how SF12 NNUE played if given limited depth. I played 4 games starting at a fixed depth of 1 ply to 4 ply. I managed to win all 4 games. That does not say much but it was fun. Tomorrow I'll try 5, 6, 7 ... ply. Here are the games.

For fun you should try playing Lc0 with a big J92 or J94 net.

And do not give Lc0 even 1 ply. Play with just giving Lc0 1 node. You will be shocked.

[mwyoung]

Every once in a while I play SF a serious game to see if I can still play chess. My record over the years is 4 losses and 4 draws. And in queen knight odds playing black my record is 1 win and 2 draws. I gave up after SF10 came out because it just seemed to be a losing battle. Today I wanted to see how SF12 NNUE played if given limited depth. I played 4 games starting at a fixed depth of 1 ply to 4 ply. I managed to win all 4 games. That does not say much but it was fun. Tomorrow I'll try 5, 6, 7 ... ply. Here are the games.

For fun you should try playing Lc0 with a big J92 or J94 net.

And do not give Lc0 even 1 ply. Play with just giving Lc0 1 node. You will be shocked.

I dare anyone to take the Lc0 1 node challenge.

[Mike Sherwin]

Great to see that someone else is actually playing these machines as well! Did you use an opening book or „just“ pure Stockfisch? I‘ll try it with limit depth as well, but doubt I’ll even beat 1.

It used a book, Perfect_2010.abk. Good luck! Has anyone rated SF12 at each fixed ply level? That would be very useful! Going to try 5 ply now.

[Mike Sherwin]

Fixed depth 5 was a draw. At fixed depth 6 I lost 3 in a row. I need to dig a little bit deeper at 6 ply. Maybe I'll try again tomorrow. If I can not get it done with the black pieces I'll try with the white pieces.

[Uri Blass]

in the game at fixed depth 6 the move 11.Qxd4 is a surprising mistake and the evaluation of 5.32 is more surprising.

The last developement version that I downloaded suggest 11.Bxd4 at depth 6(best is probably e5 but Bxd4 is also not losing for white).


I know that one of the things that I do not like about stockfish is that it can show illogical scores at small depths thanks to some stupid pruning that no human does.

7.28 for Qxd4 at depth 2.
I understand that 11.Qxd4 dxe4 is winning for white because of 12.Qxd8 but no human is going to think that dxe4 is forced because of stupid pruning and believe that he wins the rook by 11.Qxd4 dxe4 12.Qxd8 Rxd8 13.Rxd8+(moves 12-13 are missing from stockfish's pv for some reason but it is the only way that I can think of justifying the strange 7.28 score).

Every once in a while I play SF a serious game to see if I can still play chess. My record over the years is 4 losses and 4 draws. And in queen knight odds playing black my record is 1 win and 2 draws. I gave up after SF10 came out because it just seemed to be a losing battle. Today I wanted to see how SF12 NNUE played if given limited depth. I played 4 games starting at a fixed depth of 1 ply to 4 ply. I managed to win all 4 games. That does not say much but it was fun. Tomorrow I'll try 5, 6, 7 ... ply. Here are the games.

Sorry, that's all useless with all programs which do early pruning.
You need to go up at least to depth 6 or 7 to get sensible moves with SF most of times, which still is below 1ms for it.

Why should it be useless? Mike doesn't play SF to test the engine but to play chess for fun and with an opponent he has a chance to beat.
