Subject: CCC-I test set

Author: Ed Schröder

I have taken some tactical positions from my database.

They are not so difficult except one...

I call the set CCC-I

1.. Program should find the complete solution within 5 minutes.
2.. "am" means avoid move (move to avoid)
3.. "bm" means best move (move to find)
4.. "M15 or M18" means a mate in xx should be found.

The 11 positions...

2rqk2r/pb1nbp1p/4p1p1/1B1n4/Np1N4/7Q/PP3PPP/R1B1R1K1 w kq - bm Rxe6;
r1bq1rk1/3nbppp/p2pp3/6PQ/1p1BP2P/2NB4/PPP2P2/2KR3R w - - bm Bxg7;
2kr4/ppq2pp1/2b1pn2/2P4r/2P5/3BQN1P/P4PP1/R4RK1 b - - bm Ng4!;
r1bqr1k1/pp1n1ppp/5b2/4N1B1/3p3P/8/PPPQ1PP1/2K1RB1R w - - bm Nxf7;
3r4/2r5/p3nkp1/1p3p2/1P1pbP2/P2B3R/2PRN1P1/6K1 b - - bm Rc3!!;
6k1/p3b1np/6pr/6P1/1B2p2Q/K7/7P/8 w - - am Qxh6??;
3b4/p3P1q1/P1n2pr1/4p3/2B1n1Pk/1P1R4/P1p3KN/1N6 w - - bm Rh3+ M15;
7r/8/pB1p1R2/4k2q/1p6/1Pr5/P5Q1/6K1 w - - bm Bd4+ M15;
3r1r1k/1b4pp/ppn1p3/4Pp1R/Pn5P/3P4/4QP2/1qB1NKR1 w - - bm Rxh7+ M18;
1k2r2r/pbb2p2/2qn2p1/8/PP6/2P2N2/1Q2NPB1/R4RK1 b - - bm Qxf3;
r6k/6R1/p4p1p/2p2P1P/1pq1PN2/6P1/1PP5/2KR4 w - - bm b3!;

Especially "am Qxh6??" is a killer.

I will post another set CCC-II with very hard positions later.
