Why to use EGTBs... Creators of chess engines say that EGTBs are almost useless for programs: 1) If in EGTB, program cannot "play to win" in draw positions, 2) Slow HD access if program is "near" EGTB position, 3) EGTB position with complicated play (out of computers reach) is ra...

Similar problems may be solved this way: 1) Start with {P}, value of position altered =’unknown’=’u’ 2) Generate corrupted E’ database (with the only difference to normal database: now P value is ‘u’), so only a set Z(P) will get values=‘uâ€â„...

I attached file with two versions of Sukharev MT study in new topic about Wilhelm's UMSs.
Definitely, we need to ask Kirill to move our posts there...

Scorched Earth Algorithm and Unmove-engine would be powerful tools for study composers. If I understand correctly, SEA requires EGT re-generation...? An Unmove-engine seems to be easier for Effective-UMS searching. If UMS line strikes WTM duals A, B, C... with their DTM values a, b, c..., (let 'a' b...

I can make pgn file with English comments in a couple of hours. But who may explain how to post it here ready for download?

Arpad, especially good to see your added logic - Ra7-a8-a7. And different, 'non-ladder' way to rzz after 8.Kd3! Do you have EG 165? Detailed analysis here... Please note, G.Haworth's file above has analysis on only repetitions and time-wasting, not on 'study-thematic' content. The variation 13...Qg3...

The EG 165.15958 KQRKQR study by Zhuravlyov has been unjustifiably pilloried by John Roycroft with a misbegotten critique as if a computer had done all the work of discovery [as if!]. However, it is clear - a minor niggle perhaps - that the author did not identify all the 'harmless' duals, even sec...

Thanks! I started working on my own Whilhelm like program... I really like Whilhelm... Any comments, praises or flames are appreciated :) Hi Josh! Good luck with a new program! I like Wilhelm too. It is especially good for finding studies through its UMS algorithm. To be more powerful (for study mi...
