1r2r1k1/1pqbbppp/p2p1n2/4p3/P3PP2/2N1BB2/1PP2QPP/R4R1K b - - bm Rbc8; ce 26; acd 20;

Is the line with epd, bm, ce, acd enough?
Excellent!
Code: Select all
mea.exe --engine "sf10.exe" --protocol uci --name "Stockfish10" --hash %HASH% --threads 4 --rating 3495 --epd %EPD% --movetime %MT% --log 1 --output %OUTPUT%
And the filename as given by the user with --name ,thus Stockfish10.epd
All right will do that.
But perhaps [epd name]_[engine name].epd. Can be 2-moves_Stockfish10.epd if the epd is 2-moves.epd

Sure.

What output format do you like when multipv is more than 1.
If possible something like this:
Code: Select all
rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq - id MultiPV=1; bm e4; ce=30; acd=20;
rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq - id MultiPV=2; bm d4; ce=20; acd=20;
rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq - id MultiPV=3; bm Nf3; ce=10; acd=20;
So 3 epd records.
This one
Code: Select all
rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq - id MultiPV=1; bm e4; ce=30; acd=20;
is not a valid epd. We can modify it to ce 30; acd 20;
But if you really like that format with ce=30, I will do that.

My bad, of course it should be ce 30; and acd 20;

Then we can also make the id's unique, can be
Code: Select all
rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq - id "2-moves.epd pos 1 MultiPV=1"; bm e4; ce=30; acd=20;
rnbqkbnr/pppppppp/8/8/8/8/PPPPPPPP/RNBQKBNR w KQkq - id "2-moves.epd pos 1 MultiPV=2"; bm d4; ce=20; acd=20;
...
[piece locations] [side] [castle rights] [ep] id "2-moves.epd pos 2 MultiPV=1"; ...
...

OK.

Currently testing on output when multipv is more than 1. Will probably issue a beta later tonight.

input_epd: 6-moves.epd
multipv: 3
log file: Stockfish_10_mt1000ms_log.txt

Yes, computers can be very wrong, even offering stupid moves after a long search. But GMs can also be wrong after a good long think.

My point is really that so few moves into the game, it is about style (in a sense) as there is still too many moves to be played to be able to decide that a line of play is in some way 'correct'. You can't really say for most lines that this one or that one 'optimal' by letting an engine search thru the primordial soup of early (EARLY) opening play.

This is why most tournaments start with predetermined positions several moves beyond what is given here. Could any engine reach a given tabia at move 12 (24 ply) as black in a Benko gambit? No...because there is 'choice' involved to that point.

I just have to think that people spending their time and effort on these early positions would be better off...perhaps doing other things with their life. Just my opinion of course.

As a (slight) aside, I recently came across a fairly amusing book called THE FINAL THEORY OF CHESS (Gary M. Danelishen, 2008) and checked out some of the Dutch analysis...amusing. He used Deep Fritz 10 in the end. Amusing is the number of lines where the author and engine plowed straight ahead...and todays engines (and some common sense...built upon experience) show how wrong the early decisions were. Perhaps the future holds more of the same but at an ever decreasing rate. I do think we are quite a ways away from the hardware and software to get to any 'final theory', certainly 'this early) into openings...but perhaps the Alpha Zero's of the world will hasten it a bit.

Try this beta. You may request other features, let me see if it does not take some time. Sample batch file is included. log directory will be created automatically if not present. I hope this would work on other computer.

To enable multipv with other option

Code: Select all

--eoption "multipv=3, hash=128, contempt=0"

There should be no space between multipv and = sign, and between = sign and option value.

Code: Select all

Wrong:
--eoption "multipv = 2"

To see logs use a flag --log, was option --log 1

Code: Select all

--name "stockfish 10" --log

mea.exe and other files.
https://drive.google.com/file/d/1bfLzH8 ... sp=sharing

Code: Select all

usage: mea.exe [-h] -i EPD [-o OUTPUT] -e ENGINE [--eoption EOPTION] -n NAME

  -r RATING, --rating RATING
                        You may input a rating for this engine, this will be

                        move in san format, default=0
  --stmode {0,1}        for xboard engines, set this to 0 if it does not
                        support st command, default=1
  --protover {1,2}      for xboard engines, this is protocol version number,
                        default=2

and a quick addition.
I plopped this standard Dutch position:

1.d4 f5, 2.c4 Nf6, 3.Nf3 e6, 4.g3

Into the developmental version of SF 10 - 17/05/19 and the top two suggestions after 41 ply are:

4...Bb4 +.66
4...g6 +.51

Everyone knows Alekhines ...Bb4 is not the right way to go here.
...g6...I think it is called the 'Christmas Tree' variation...which is not played much (doesn't make a lot of sense really).

I believe 4...b6 might have been the 3rd suggestion (don't remember for sure) and we all know you do not fianchetto the light squared bishop in this position.

Seemed like the reason is this. I did install a DDG extension.

Have to add it to white list.
