Mate in 22. Is this correct?

SF is not designed to solve mates, but Matefinder is: Analysis by Stockfish MateFinder 9 64 BMI2: 1.a6 h5 2.a7 h4 3.a8N h3 4.Nb6 cxb6 5.c7 b5 6.a5 b4 7.c8N b3 8.Nd6 exd6 9.e7 d5 10.e8N d4 11.Nf6 gxf6 12.Ke6 f5 13.g7 f4 14.g8B f3 15.Bh7 f2 16.Bxd3 f1Q 17.Bxf1 d3 18.Kf6 Ne2 19.Bxe2+ c1Q 20.Bxd3# +- (#...

16 GB is too much for 7,5 s per move. TCEC uses 16 GB for 5 hour games with 43 cores. Which one were more expensive GPU RTX 2080 ti or Threadripper?

WOW new engine with start rating of 3400 - this is history .

Yes current situation in TCEC is surprisingly even! BTW in CCC5 SF is leading 17,5-12,5 against Lc0 t40. Wins 6 - 1 and one obvious tactical loss for Lc0.

.. blunder!? And they were consecutive games. In chat they say T40 makes same blunders. I will not invest one euro for new GPU .

Fun fact: Critter 1.6a = Houdini 1.5a.

This +130 gives nice 3700 ELO! Maybe the upper limit for chess?

Any idea what's the secret of tactical Houdini? It also gets 200/200 in Arasan suite eventually. Obviously not only nullmove change, but something else!?
