A WDL will work only if you have all sub-WDLs that can be reached by captures from the WDL. (So just make sure you have all 6-piece WDLs if you want to use any 7-piece WDLs.)
in this sense - of course, 6 (and 5-men) are available. they are small and useful anyway and full set is easy to store

Re: Sicilian engine-engine annihilation

Below is an amazing annihilation by SF12 in less than 30 moves of a 3300+ opponent. Free piece in exchange for mobility and development similar to those Paul Morphy classics.

Re: Syzygy 7-men minimal set

I may be mistaken, but i thought for pawnful egtb's you had to have all the pawnless files first as a dependency. Is that correct? If so that list wouldnt work. no dependency, any single WDL will work What is a good subset to get? The one which will maximize TBHits, here is good start: http://talkc...
