Re: STS rating v13.1 for Lc0 0.21.2 with nodes = 1

I just want to say that I think the distinction between "tactical" and "positional" problems is rather arbitrary and not so useful, because in real chess games good positional moves are found by tactical details. For example, let's say that rook on the 7th rank is usually good (with whatever conditi...

Re: Komodo MCTS

With that setting, Komodo 13.02 MCTS is MUCH stronger than normal Komodo, and about the same strength as Stockfish 10 (also using MultiPV). But why set SF multPV too, when that'll weaken it? What is the elo drop of SF with multiPV > 1? The idea is to test the engines the way many users actually use...

Re: Komodo MCTS

Now try the same match at MultiPV=4 (as some people use in analysis) :wink: :wink: I used the maximum number of cores for the engines that my P5 processor allowed, MultiPV=5. Ponder=Off. Did you set MultiPV = 5 for ALL engines, not just Komodo? With that setting, Komodo 13.02 MCTS is MUCH stronger ...

Re: armageddon in norway chess

IMO, a scoring system that disincentivizes draws and rewards wins more, especially with Black, should be better than messing with the fabric of the game (by introducing weird variants). Such an alternate scoring system was discussed here a while ago - HGM made an interesting suggestion, but I don't...

Re: armageddon in norway chess

So Norway chess round 1 concluded with 5 draws, but White won 4-1 in the 10-7 (+3 sec inc from move 60) Armageddon game, Black getting less time but draw oddss. This suggests that Armageddon is valid in longer games than blitz, as was also shown in some U.S. Championship playoff games at odds like ...

Re: armageddon in norway chess

They do their best, the game is just too drawish as is. 50% draws is acceptable, but 75% or more is not, if we want people to be interested in chess. Wait, why is so much time and effort trying to save chess if it's a dying game and people could be playing a better game that isn't so drawish in nat...

Re: Komodo MCTS

"ply" has no real meaning in MCTS mode, we just display a number that is calculated from the number of Monte Carlo nodes, it's quite arbitrary. If ply stops increasing, it must be because you filled up the MCTS hash so nodes don't increase. Try a much larger setting for MCTS hash. Lqrry, is the MCT...
