The first 9 are, as far as I know, rather balanced - the Nunn endings: 8/1ppr1kp1/p1p4p/8/8/5P2/PPP1RKPP/8 w - - 0 1 8/1pk3pp/p7/3p1p2/3K4/6P1/PP2PP1P/8 b - - 0 1 8/4k3/r4pp1/pR6/P4KP1/5P2/8/8 w - - 0 1 8/p1p1k3/1p1p2p1/3Pq2p/2P1P3/1P3QPK/P7/8 w - - 0 1 8/p3ppk1/1p4pp/3nN3/6PP/1P3P2/P3PK2/8 w - - 0 1 7k/pp4pp/2n5/8/8/P7/1P4PP/2K1B3 b - - 0 1 8/8/p4Bp1/1pPb2P1/1P2kp2/P7/5K2/8 w - - 0 1 8/4k3/p1B4p/2K5/1P4bP/8/8/8 b - - 0 1 3R4/1p6/2b5/2P1k2p/p3p2P/P6r/1P2KB2/8 b - - 0 1 The following 11 are unbalanced positions to test the engines knowledge about specific themes - not covered in the Nunn positions. 8/5b2/1k2p1p1/2NpP1P1/1K1P4/8/8/8 w - - 0 1 This one is about "good knight vs bad bishop" - a typical French position. White is winning. 8/5p1k/r5pp/P7/3R3P/6P1/5PK1/8 w - - 0 1 This is a rook ending - theme "rook behind the pawn". White is winning. 4b3/5k2/4p1p1/3pP2p/2pP1P1P/2P5/6N1/2K5 w - - 0 1 Another "good knight vs bad bishop". White is winning. 8/1p1b2k1/p1p1p1p1/2P1P2p/1P3P1P/P2B4/5K2/8 w - - 0 1 "Good bishop vs bad bishop". White is winning. 6k1/2p3np/1p1p2p1/3P4/1PPK1R2/6PB/7P/4r3 w - - 0 1 "Giving up material for positional advantage". R+B vs R+Kn. White wins. 1n6/4k2p/p3ppp1/1pPp4/3P1PP1/3NP3/P3K2P/8 w - - 0 1 Knight ending - white is winning. Maybe too easy? 3r4/7p/Rp4k1/5p2/4p3/2P5/PP3P1P/5K2 b - - 0 1 "Activity in rook ending". Black can draw this one. 8/4k3/1p2b1pp/p1p1p3/P1P1P3/1P3P1P/5KB1/8 b - - 0 37 "Good bishop vs bad bishop". Black is winning. Maybe too easy? 2r5/1p1k1p2/p2p2p1/P1PPnp1p/1P1K1N1P/5P2/4R1P1/8 w - - 0 1 R+Kn vs R+Kn - "Giving up material for positional advantage". White wins. 8/6b1/4k2p/p1p1p1p1/2P1K1P1/PP3N1P/8/8 w - - 0 1 "Good knight vs bad bishop". White wins. 2r3k1/4pp1p/3p2p1/p2R4/1r6/1P4P1/P3PP1P/R5K1 b - - 0 1 Double rook ending. Black should have good chances of winning this. /S
