Re: Does any engine find the best move here...
Engines that do not find Kh1 first, are probably faster like Stockfish? Kh1 that seems like just two waiting moves, Kh1 and Kh8 but that is not entirely correct because this line is now winning after the 'tempo moves'. With one thread it takes Kaissa more than 50 minutes to find Ng4 after Kh1. Because of the 'elastic' I introduced for Uri's position, if the PV finds an entry worth more than a Knight in the midgame it will add an extra ply for the full node, I think Kaissa gets the highest scores, well above +5 and the largest seldepths of over 140 in the PVMikeB wrote: ↑Thu Jun 27, 2019 9:14 am [d]r3r1k1/1b1nbp1p/1qn1p3/1p1pPp2/p2P4/P2BNN2/1P1Q1BPP/R4RK1 w - - 2 19
Clearly white has the initiative, but there is one move the that stands far above the rest.
Might be an excellent position for Lc0 on fast hardware...

Re: Does any engine find the best move here...
Zappa Mexico found it in 45 seconds...
Chief
PS.
It took Eman 1 minute 28 seconds and McCain (Tactical=3 and MPV=4) 1 minute 3 seconds.

Re: Does any engine find the best move here...
Go figure, today its finding it in 17 seconds ( with some minor changes):Eelco de Groot wrote: ↑Fri Jun 28, 2019 9:03 pmEngines that do not find Kh1 first, are probably faster like Stockfish? Kh1 that seems like just two waiting moves, Kh1 and Kh8 but that is not entirely correct because this line is now winning after the 'tempo moves'. With one thread it takes Kaissa more than 50 minutes to find Ng4 after Kh1. Because of the 'elastic' I introduced for Uri's position, if the PV finds an entry worth more than a Knight in the midgame it will add an extra ply for the full node, I think Kaissa gets the highest scores, well above +5 and the largest seldepths of over 140 in the PVMikeB wrote: ↑Thu Jun 27, 2019 9:14 am [d]r3r1k1/1b1nbp1p/1qn1p3/1p1pPp2/p2P4/P2BNN2/1P1Q1BPP/R4RK1 w - - 2 19
Clearly white has the initiative, but there is one move the that stands far above the rest.
Might be an excellent position for Lc0 on fast hardware...
