I am especially fond of this one. Can you create the following table for positions without analysis: [Frequency of hits] [EPD position] e.g. 600213, r3kbnr/ppp2ppp/2p1bq2/8/4P3/3B4/PPP2PPP/RNBQK2R w KQkq - 600001, r1b1k1nr/2ppqppp/pbp5/4N3/3PP3/2P5/PP3PPP/RNBQ1RK1 b kq - etc? That way, we can process the most important rows first. It would be especially good to build an enormous book using a ton of PGN, if you know what I mean. That way, we will get the best stats from real usage. >2) >It's also possible to look at the current EPD's <= 30 ply from the initial >position and look if the move crafy recommends is an EPD positon that's already >in the CAP data.

What if one is ten plies and the other is 19 plies?
