This reappeared recently at rybkaforum.net. Apparently it's mate-in-15.

Qxg6 was the first move i considered, strangely i didnt considered h5 first :-)
After the obvious moves: 1.Qxg6 Kxg6 2.Ld3 Kh5 3.g4 Kxg4 i opted for Raa1 which is a weak move..instead SF quickly showed Rg1+ and i let SF show me the mate...nice isnstructive queensac which shouldnt be too difficult to spot for humans although the determination to the mate isnt that trivial :-)
bm 1.Qxg6 with mate in 15 seems best :-)

Stockfish solves this, but not easily. And it hasn't produced a mate score:

I wonder if that depth 35 was somewhat reproducible, because others stated that Stockfish only in rare cases can find it, maybe many threads help. I had many cases of not finding it but also one case of search luck with a modified latest master:


1r4r1/3q1npk/2b1pbnp/Rp1p4/1N1P3P/2PQ1pP1/1K3B2/5B1R w - -

Engine: RS20140517_008 MP (Q6700, 4 threads, 512 MB) Latest change: No check extensions anymore! Only the singular extensions remain.
That it still finds it is because the extensions are exchanged for less LMR reductions. But it may be a very lucky run.

Because of the LMR changes, even though the extensions are gone, the bench is not extremely low, just average for Rainbow Serpent. LMR is very important if you want to reduce time to depth but of course it has a price in some tactical positions.

Debugging is twice as hard as writing the code in the first

are, by definition, not smart enough to debug it.
