Honey XIr1 source released

[MikeB]

Is there any comparison with a recent vanilla Stockfish in strength? I was thinking to put this engine on my website.

I have no issues, but please also provide the link the source. And you may also link directly to the Github release page where the exe's are located if you wish ( which would be my preference)...one link covers both source and exe's
https://github.com/MichaelB7/Stockfish/ ... /tag/Xi-r1

My testing shows:

about 50 Elo weaker at 60 sec +.6 sec inc -
about 2 or 3 Elo weaker at 150 sec + 1.5 sec
and out of respect for my Stockfish developer colleagues, I will let others opine on the strength at 10 min +6 sec inc games...

besides lots of hash, syzygy, and threads, what other setting maximize finding mates the quickest?

It depends on the position and how deep the mate is, how many pieces are left on the board - Crystal and Matefinder by Joe Ellis are better at finding mates.

For human play - Bluefish is my favorite. For analysis, Honey and Black-Diamond, I use Stockfish for testing Honey and I hardly touch Weakfish or Blue Honey.

I tried Black Diamond in mate solving. It was slightly better than Crystal 2019. But there is still this ugly bug:

After finding shortest mate it's forgotten and longer mates are found .
