Re: World Fischer Random Championship

It seems to me that Fischer Random is working out better than I expected; I thought it would solve only the preparation problem in chess, but it seems to be doing wonders for the draw rate as well, as has already been shown in computer chess in the CCRL testing. Do you have any thoughts on why Fisc...

Re: longest 6-man EGTB win

Hmmm... There must be a communications issue. I'm not asking that the files be changed in anyway. Just for a short, representative list, (1 from each of several EGTB files (e.g. 1 from the KQPkrr file for example) of positions which represent a long mate that respects the 50-move rule. syzygy lists...

Re: Tactics cannot be very important for chess

"Tactics is what you do when there is something to do. Strategy is what you do when there is nothing to do." BTW, the NN engines do not prove that tactics is not important. They prove they can avoid it against conventional engines. But the conventional engineswere never tuned to seek tactical compl...

Re: Tactics cannot be very important for chess

Maybe you can define tactics as a move that humans can be convinced by analysis with engines that it force a win(or a draw) when it is clear that a different move is worse. Again it is not a clear definition Could you not also define strategy that way. ?Why not a tactical move is a move that within...

Re: Tactics cannot be very important for chess

Given that a mathematical proof that chess is a drawn game looks out of reach right now, maybe a combination of knowledge and search can take us to the highest point which can be reached: a player that never gets beaten. So that would be a player that can never be beaten by itself even if given 10 ...

Re: longest 6-man EGTB win

maybe the simplest way to get an idea wether Lomonosov TB's are right is to play the first 50 moves vs DTZ50 TB's and if its not a draw after that then Lomonosov TB's might be right here (oc this will be no proof but an indication at least) ...or do i get the whole thing wrong and you guys dont car...

Re: longest 6-man EGTB win

@ duncan I know, but this matt in 125 is wrong! Is according to Lomonosov matt in 68 as i wrote !! So longest mate is only 114.

Re: longest 6-man EGTB win

I tried to look for the 10 longest DTM in descending order. The longest I could find was mate in 125. Does this look at all accurate to you. ? Mate in 125 ? It is a mate in 68 !!

Re: longest 6-man EGTB win

The problem is that this information is not in any of the existing EGT. The DTM tables don't respect the 50-move rule, so that positions with large DTM might actually be draws. The DTZ tables do tell you which positions can be won respecting the 50-move rule, but they do not tell you their DTM. I t...
