Hi Paolo, thanks for your response. > About the tablebase support, did you consider > linking to an online tablebase service?
Yes, querying an online tablebase server is included in this support as the primary choice. > Those tablebases are getting so huge that local > support might not be practical. Yes, but I will support two tablebases: 1. The Nalimov tablebases, because these are the most widespread ones, some users are already using these with Scid. And I've already implemented this tablebase support some years ago (but still not yet tested). 2. The Syszygy tablebases: these tablebases are quite small compared to other ones, and provides the DTZ (Depth to Zeroing-move), but the online query does only give the DTM (Depth to Mate). DTZ provides the additional information whether an endgame can be won without failing due to the 50 move rule. With the DTM/DTZ information the engine analysis is complete. Scidb will offer a download service for these tables. I do not have a server for online queries of the DTZ, and the Syzygy bases are relatively small. Gregor
