Analysis of positions

(I think with some upcoming patches we can do this in GUIs together with -l lzcdebug.log).

Cut output at the point you want to test, and put into a file e.g. missmate.cmd:

Generate logfiles for different gen nets:

rm gen006_de1d.log; cat missmate.cmd | ./lczero -w ~/lcnetworks/gen006_de1d -t1 -s1 -p800 --noponder &>> gen006_de1d.log
rm gen009_b91f.log; cat missmate.cmd | ./lczero -w ~/lcnetworks/gen009_b91f -t1 -s1 -p800 --noponder &>> gen009_b91f.log
rm gen011_6d2e.log; cat missmate.cmd | ./lczero -w ~/lcnetworks/gen011_6d2e -t1 -s1 -p800 --noponder &>> gen011_6d2e.log
