Taking ideas is not a vice, it is a virtue. We have another word for this. It is called learning.
But sharing ideas is an even greater virtue. We have another word for this. It is called teaching.

Re: Long mates that can probably be shortened

Post by Andrew »

I just finished analysing Dan's positions using DeepShreder13, Crystal 220819 and Stockfish 200220.
4 threads, 6 men Syzygy TBs at least 30 minutes and longer if showing a mate score or promise of seeing one soon,
sometimes let Crystal run overnight.

I've included below positions where at least one of he engines found a mate score.
Have also abbreviated the fen for the position.

I also have added a text file with the full lines.(analysis cut from the line prior to the first mate score)

Okay attaching didn't work. Can email it to Dan if he wants or upload it somewhere if someone has a suggestion?
