Very interesting ending, can white win this position?

8/1b6/1kn5/3K4/5Q2/8/8/8 b - -

It's also one of my correspondance games. I don't know if this ending Q vs B+N exists in the 5 pieces tablebase

Black loses in 30. - The 5-piece tables are complete, also 6-piece I think... This site offers to look them up (except 5 vs 1 tables):

It's really outstanding the work that was done by Nalimov for his table bases. Can someone remind us how they were created?

There is a long Wikipedia article about chess endgame databases, which includes a description about how they are generated. It is a general description though, not only for the Nalimov tablebases format. But I think the general logic is the same. The article also explaines DTM, DTC etc.
