Oops, sorry, but no. I fear I've deleted it by mistake, thinking it to be an older one, I had already answered.
Can you send again, please?

You're correct, Rxc3 is good, but winning the game was just a plus,
Yes, a plus based on White blundering.

Re: Test Position bm Rxc3

Again, CF is showing incorrect lines, after 41.Rfe1 above, 41...Rb3 is not optimum but 41...Nb6! with a possible winning line. This is Multi-PV with the best move and ends with a 0-1 If you follow the Multi-PV of AB engine you would agree, that below line is all top moves, and ends in a win for bla...

Re: Test Position bm Rxc3

because I was using my weak smartphone earlier to check those lines, after 36.Nf1 the direct Bxf1 looks incorrect, that's why I traced your PC output just now but the Nb6 (Sb6) on your first post looks not top move of engines, it was only 6th. (35. Qa1 Na4 36. Nf1 Qe4 37. Rf2 Bxf1 38. Rexf1 Rb3 39....

Re: Test Position bm Rxc3

Neither has this line been refuted... e4 is absolute key move, cutting blacks ability to pivot on that square. 30. Ra1 Bd3 31. e4 dxe4 32. Qa4 Nb3 33. Ra2 is better than the above Rad1 (which threatens nothing and allows black to improve his position) after 33. Ra2 Nc1 is just drawing, Nc5 also a d...

Re: Test Position bm Rxc3

What happens after your above line 36...De4 37.Tf2, then 37...Bxf1 38.Rexf1 Rb3 because I traced with AB Multi-PV playing only best moves from both sides and I ended up with a win for black. Why not show this complete win then, Mike? Or, even better, refute the output- line from my previous post, c...

Re: Test Position bm Rxc3

Complete game with your Nf1 possibility inserted at move 35 and black still has positional dominance to compensate for the exchange sac: [Event "?"] [Site "?"] [Date "????.??.??"] [Round "?"] [White "Stockfish 10 181129"] [Black "Lc0 0.21.1 N:42100"] [Result "0-1"] [TimeControl "5400+5"] [SetUp "1"...

Re: Komodo 13 released

Each MCTS tree entry is about 40 bytes, and an hour has 3600 seconds, so 1400 * 40 * 3600 is about 200 megs an hour. Sorry, Mark, but knowing this calculation already from Readme, isn't there (at Readme) one 0 missing? There's about the same example given for 8 cores and 5 hours and factor is 1000 ...
