40 moves in 10 seconds is a little too fast for Joker80. So, I've opten for 40 moves in 30 seconds; I might be able to get away with 40 moves in 15 seconds. Joker80 randomizes its move enough that it's worth it to have it run a few thousands games against itself; a version of Joker80 that essentially randomizes its first two moves would be nice too (or I can have the script just give the engines one of the 784 setups where the first two moves are randomized).

Here is the script that does this:

#!/bin/sh

A=1

while : ; do

        winboard.exe -cp -fcp joker80.exe -scp joker80.exe \
          -boardSize middling \
          -variant capablanca -lpf schoolbook.fen -tc 0:30 \
          -mps 40 \
          -autosave -sgf game-hour-${A}.pgn -mg 60

        A=$(( $A + 1 ))

done
