Hi John,
What is the difference between your 5-1 generation and Martin Kreuzer's one (1 year ago)?

Can you compare (check) your results with his?

Hi, I want to use John Tamplin's DTZ50 EGTB in http://chess.jaet.org/endings , in order to obtain the shortest legal mate (of course with Black's best defense) for the following KNNKP position: 6k1/8/8/1N3p2/6K1/6N1/8/8 w 6k1/8/8/1N3p2/6K1/6N1/8/8 w The DTM EGTB shows that it is a mate in 55, ignori...

..."because of some reasons."
Why don't you tell us the whole story?
Doesn't sound very practical...
Why don't you put them on some USB key...?!

Something looks fishy : 33e302e181804f085dbe07fe763edc59 *krrnk.w.cmp 33e302e181804f085dbe07fe763edc59 *krrrk.w.cmp ?????? By the way, Kirill, can you post a "simple and to the point"" answer to my thread "5-1 EGTB Status. What is needed to make them useable? " I must say I ...

Can somebody give the actual status of the 5-1 EGTBs ? Is there a prospect that some day, they may be used in the same way as the other 6-man Nalimovs, in chess programs (that is, either during the search, or at least as a static database)? My understanding is the following: 1. the existing Nalimov ...

Some years ago, I got quite interested in 5x5 chess (playable on "Zillions of games"), where each player has the 5 pieces of chess and 5 pawns.

Do you know if anything has been written about it?

I can't read German but I am doubious - USB keys are so much slower than disk - even the faster ones. I have a 4GB Corsair flash voyager here and it is so slow compared to disk (even for read) - now I realise why hybrids have not caught on yet. Shaun Hi Shawn, Well, the Corsair flash voyager certai...

Hi, I have seen a recent test of endgame search with the 5-piece Nalimov EGTB on 2 x 4 GB USB key (of course also possible on 1 x 8 GB key). Seems all the disk access inconveniences are gone!... Which also means bitbases (Shredder 10) are no longer useful. For those who read German, see http://www.c...

I'm not sure what you mean about "results for position analysis". Sh'bases just indicate win/draw/loss and are assumed to be correct for that: they don't say whether a position is closer or further from a win. But they do filter out those moves that don't preserve current theoretical valu...

Stefan M-K kindly provided me with an upgrade to SHREDDER10. The analysis window shows the counts of accesses to Shredderbases (SB) and to Endgame Tables (TB). I am assuming, rightly or wrongly, that SB/TB is the factor of speed-up as it shows that TB rather than SB accesses to the EGTs needed to b...

If John Tamplin's DTZ50 EGTs were available at http://chess.jaet.org/endings/, one could look up the KNNKP position 8/4k3/8/8/5K1p/5N1N/8/8 b and see if this is likely to be won under a 50-move rule. This is precisely the sort of position that illustrates the need for DTZ50 information if not DTR/D...

I have this endgame position 8/4k3/8/8/4Kp1p/5N1N/8/8 w - - 0 1 2 Knights vs. 2 Pawns, which is Mate in 60, as any look at the 6-man DTM EGTB will confirm. But is there a "legal" mate (with the 50-move rule) ? How can this be looked up, since I don't think a corresponding DTZ50 table is av...

Hi, Shredder 9 is has been out for quite some month now, but nowhere have I seen a report on the actual gain obtained, in endgames, with the use of BitBases added to Nalimov TableBases. I assume that the usual setting is to have both the 5-man BitBases (400 MB in memory) and the 5-man TableBases (7+...
