Re: starting to build 50 move rule test suite

Why "of course" ? ... :mrgreen: Qxc8 mate Because Qg8+ would be ply 99, Bc8+ ply 100 - and that's draw before White can do Qxc8 as this would be ply 101. Btw., that's also interesting as engine test for engines that solve the first one (with 98) correctly: if you replace the 98 by 97, Qxc8 will be ...

Re: UCI Win/Draw/Loss reporting

So what is agreed up on: info wdl 200 600 200 format for uci I'd add in to make the latter two numbers optional. So "info wdl X" with 0<=X<=1000 would mean an expected score, but no information on the distribution of wins, draws and losses as e.g. LC0 only gives a score expectation. Always permill ...

Re: UCI Win/Draw/Loss reporting

What do you mean "look the same"? That it must not matter which engine the GUI loads, it must look the same. That some parameters like hashfull are optional in UCI is a completely different story from sending tabular data and as you suggested even with colour formatting, arrows and whatnot. ou are ...

Re: Dylan Sharp Vs. Harvey Williamson (G4)

Can you provide one example at a time control like this one? What you say is certainly true, but is much more common at very short time controls. Inn correspondence chess, players who follow Stockfish blindly are not too hard opponents for experienced correspondence players. At least one, maybe eve...

Re: Dylan Sharp Vs. Harvey Williamson (G4)

As for Stockfish says, Stockfish says: there have been quite some games against LC0 where Stockfish thought it was completely fine - only that it wasn't and found out too late. The interesting question is whether this game will lead to positions that Stockfish simply doesn't understand - and obvious...

Re: UCI Win/Draw/Loss reporting

A programmer can display any data he wants in good visual forms without waiting for chess GUI developers to add them. That's not an advantage, that's a disadvantage. A GUI is supposed to look the same no matter which engine is running underneath. Consistency is an important part of usability. Also,...

Re: UCI Win/Draw/Loss reporting

if we would get dozens of new infos That YAGNI will hardly make it across many engines or GUIs anyway. WDL is different because NN engines like LC0 have a different way of expressing the evaluation - not in centipawns, but in terms of probability. That's a fundamentally different kind of strong che...

Re: UCI Win/Draw/Loss reporting

Why that configuration stuff at all? Just include the WDL with the three values for win, draw, loss in the info from engine to GUI. UCI explicitely specifies ignoring unknown things and continue parsing. If a GUI barfs on the wdl inside the info, it is not UCI-compliant anyway and should be fixed: *...

Re: Dylan Sharp Vs. Harvey Williamson (G4)

What are the conditions of this game? Is there any time control? Do the players use computer analysis?
