philidor began using 21 moves as an arbitrary guideline when playing in coffeehouses. i guess this was primarily because he could see whether his opponent was actually making progress or not in the majority of cases. this information is contained in one of his diaries, published after his death, whi...

my aim is quite clear at this point: i don't want to completely fill my raid with tables at the moment, so i will limit to 5 + 6pawnless. these will be online at all times gambit is online, once acquired. that generally translates at the moment to ~4 hour stretches beginning ~9am monday, thursday, s...

as far as i knew, there was never any coffeehouse 50-move rule, that one was 21 moves. also, it came AFTER the 50 move rule was introduced to counter one of steinitz's strategies - if the game looks lost head for infinity if possible. steinitz won more than his fair share of [recorded] games by play...

DTZ EGTs for endgames with maxDTZ > 50 are not just 'academic'. A fallible player may not defend optimally, and observations show that human players do not attack or defend optimally. Thus, wins which are theoretically going to be frustrated by the 50-move rule may in fact be won. a highly interest...

the whole sharing 24/7 is better already than i personally can do at this point. kudos on that one. small list you have, but it will expand quickly if left permanent online.

very interesting... will they come in albatross? :> seriously, i personally think i will wait a little while after initial release on this one... at least until the initial flurry of bugs is over, but for those in a hurry... why not? i've read about this idea long ago already, and as long as they ca...

now curious. i haven't looked yet, but does this m330 satisfy dtc50? or is it academic best and too long for tourney? the latter seems only possibility given two kings and only 5 (x50=250 moves) other pieces. now have looked and while interesting for academia, it is clearly not tournament possible e...

You seem not be able to argue rationally or to explain what you mean, and continue with your baseless claims. I am not going to waste my time with this any longer. why did you waste MY time this long? yes, you authored wilhelm. so? i am telling you what behaviour i have seen. oh, and perhaps there ...

short answer is no. long answer is if you put the entire directory on (very) low priority and the completed files on high priority (not auto), the effect is similar. this can be done in the shared files screen by right clicking on the relative directories and selecting appropriate priority from the ...

Now, how to construt that list is another matter. I don't think that simply counting endgames that actually occurred on board is the best way, as many endgames may be probed in search. So here I agree with you. Engines don't log which tb they probe, so it's hard to know. One simple way may be: Simp...

What are you talking about?? To clarify this: The integrity check of Wilhelm is of course independent on subsets. Rafael B. Andrist -in. if you don't have complete subset of [tb], wilhelm will still check its random position, and if that position references another table that is not present, will g...

since the advent of win64, it is possible to generate 6 man tbs on a home pc... however, with the time and swapping involved in doing so, i wouldn't recommend it...

ok REALLY off topic fo rthe first part here, but josh, forget any nature of burrows transform for tables. on the bigger ones that compress less, datacomp will do better. i can tell you this for sure without ever having to look further into it. best bet would be something along the lines of a modifie...

three words, wilfried: read the source.

interesting, since i have 299, and that includes all, and that was also from generation. with tbgen, the original recompiled to allow pawned 5 man. and the white and black are produced together, not separately. at the same time even. and only if both subsets are present. try again, this time recheck...

to testing with wilhelm: unfortunately, it seems to be a ''feature'' of wilhelm that if the subset is not present, regardless of accuracy of generation, file will be called flawed if the random test position happens to jump to a subset table that isn't there. to my methods of testing: point 1, yes. ...

DTZ=Edwards (chessmaster) bases?

Usenet has many benefits. Downloads are usually faster compared with p2p and the transmission may be protected by parity-files. in fact, usenet backbone is 4 oc12 cables, so their bandwidth is limited to 4x288x28.8kbit. that is to say, there are 1152 channels, each of 28.8kbit throughput. so the sp...

ahh the beauty of incomplete subsets to wreck an otherwise perfect thing. as far as i can tell , the krppkr.2 file released flawed by chessbase has been replaced. it was pyhsically the same size as the correct one, but had a different date stamp (how you could tell by file on dvd). it passed the dat...

my entire point was that there is no one ''more useful'' set when it comes to tables. as stated before, krppkr positions being searched by an engine will access every position with a pawn and 2 rooks, plus every position with 2 rooks, plus every position going to 5 men from these (all). that is WAY ...

I am sharing all 33 pawnless bases at "Kirr" machine, so you should be able to see them. ... No, it does not mean they will never be uploaded! It just means they will be uploaded much less than with higher priority. ... Yeah I also have uniform upload priority ("Release") for al...

i'm writing this because i've been experimenting with emule settings. i've been having trouble collecting some of the less popular 33 bases, so i've been sharing mine with other than default settings, and gambit has been almost constantly uploading at 100kB/s since the changes: as far as optimum upl...

one thing only here: parity and stop bits mean 128kb/s=12.8kB/s this has been true since 110/75 kermit....

I thought the "nbb" part of symmetric sets is not necessary at all? All engines that I tried are happy without it, they just use "nbw" part for both white and black. Do you know any engine that particularly requires having both files for symmetrical sets, even though they are id...

as to verify with tbgen, the format is (query table) tbgen -q [table] with requirement of complete subset of table. that is 100% verify... filesize, correctness, etc. it only verifies one random position within the table, however the code can be altered fairly easily for a complete check, and anyone...
