Which is the longest chess game among chess engines ?

[Chessqueen]

I Know that between Humans this has to be the longest ==>

At the Moment I have Dragon 3.2 Vs Stockfish playing at 3 minutes per move for over 94 hours and so far the game is still going with 299 moves and it looks like it will go for another 80 moves at least there are lots of pieces on the board

I've had a few games that were 300+ moves long.

So far this has been the longest chess game between two engines ==>

Hello Graham:

I've had a few games that were 300+ moves long.

Brute force solution: download all games of CCRL Blitz and CCRL 40/15, then parse the PGNs with joined tool, which gives interesting stats:

Code: Select all

.\joined>joined -h
Illegal option: h !
Usage: joined [<*.PGN, *.FEN or *.EPD file>] [-<options>]
Legal options are:
   -p        : Print messages to both stderr and stdout
   -q        : Quit after scanning input file
   -r        : Initial value for random algorithm
   -s        : Print messages only to stdout
   -v<number>: Set verbose level to <number> (default 4)
      The numbers may be added. The numbers are:
       1: Print PGN
       2: Calculate number of legal moves in all positions
       4: Print progress (default)
       8: Print all warnings
      16: Check PGN
      32: Report result = '*'
      64: Get statistics on all types of moves
***** Error exit *****

Analysis from other sources such as CEGT are welcome.

Downloaded files: CCRL-404.[2947648].pgn and CCRL-4040.[1535226].pgn

The lengths of the games are expressed in plies, i.e. 199 plies mean 100 white moves and 99 black moves (what we usually call 100 moves).

This is a drawn opposite colour bishop endgame.

------------

What is the longest possible game? It depends on draw by 50-move or 75-move rule and draw by 3-fold of 5-fold repetition. The following site deals with the calculations, claiming almost 5900 moves for 50-move + 3-fold and almost 8850 moves for 75-move + 5-fold:

The longest possible chess game, and bounds on the number of possible chess games

Longest decided games - rather than drawn games - is a bit more interesting to me. Depends also what adjudication settings a tester may have set in the GUI. Frank from memory had no adjudication at all, so he must have many long games.

Below is a 291 move won game from my recent Chess324 tournament:

Longest decided games - rather than drawn games - is a bit more interesting to me. Depends also what adjudication settings a tester may have set in the GUI. Frank from memory had no adjudication at all, so he must have many long games.

You are correct because I set up Arena NOT to resign unless the difference was estimated to be way more than a Queen advantage more or less a Queen + a minor piece of an advantage, but anyway here is another long long game ==>

Hello Ray:

Longest decided games - rather than drawn games - is a bit more interesting to me. Depends also what adjudication settings a tester may have set in the GUI. Frank from memory had no adjudication at all, so he must have many long games.

Below is a 291 move won game from my recent Chess324 tournament:

Where Lc0 repeatedly delays a shorter win: after 222.- Kxd4, white loses in 14 moves with 223.- Kb5.

Hello Ray:

Longest decided games - rather than drawn games - is a bit more interesting to me. Depends also what adjudication settings a tester may have set in the GUI. Frank from memory had no adjudication at all, so he must have many long games.

Below is a 291 move won game from my recent Chess324 tournament:

I revisited the two PGNs that I mentioned in my first post. The longest non-drawn game that I found is the following one (from CCRL Blitz):
