Fonzy
Hi Fonz, thanks for trying it with Dirty. Without Null move it is faster but not so much faster that it certainly is Null Move. More general pruning problem with Stockfish is also possible.
The almost latest Stockfish up to the Enhanced Verification Search I let search a bit longer and it did find Nab3+ but instead of Dirty's 58 seconds it needed 51 minutes. So that could be improved.

Many, many thanks for this.
I noted
Code: Select all
cp $(EXE) /Users/michaelbyrne/cluster.mfb/$(EXE)
in your Makefile
That wasn't the only issue, and I had to wait for Lucas Monge's compiles. Many thanks to him too, without whom I wouldn't be using your engine.

As I said SF solves this in most tries with syzygy, but never without. 3 tries with 4 core :

Hi Jon no difference -except for the fact that having two sets of complies helps ensures there is a working version for someone.

Latest Cfish solves this without endgame tables, so I assume that Stockfish can too:
