This is a test suite I've made. All positions are taken from 1001 Brilliant Ways To Checkmate. Most of them aren't difficult as such. Still, all of these positions weren't found as fast as I'd like with Chezzz, so they can be used for tuning of extensions, mate search etc. Some of them (starting about BWTC.933 or so) are positions where it isn't necesarily difficult to find _some_ mate, but usually, the shortest mate (which is the point of these positions, which are compositions) can't be found if you're using null move, for example. I don't know if you can use this suite for anything, but I would like to see how your programs are doing with it. 2qrr1n1/3b1kp1/2pBpn1p/1p2PP2/p2P4/1BP5/P3Q1PP/4RRK1 w - - bm Qh5+; id "BWTC.31"; r3k3/ppp2N2/3p1n2/2b1p3/2BnP1b1/2NP2p1/PPPQ1PPr/R4RK1 b q - bm Nf3+; id "BWTC.406"; 1nbq1r1k/3rbp1p/p1p1pp1Q/1p6/P1pPN3/5NP1/1P2PPBP/R4RK1 w - - bm Nfg5; id "BWTC.439"; 5r2/2p3pk/1r1p3b/p1q1p3/6R1/P2P1p2/BPPQ1P1P/2K3R1 w - - bm Qxh6+; id "BWTC.522"; 5rk1/4R1p1/pqpp3p/2bp1b1Q/5P2/2P4P/P2B2PK/4R3 w - - bm Rxg7+; id "BWTC.544"; r3nr1k/ppqbNpp1/7p/2p1p3/2B4Q/P4P2/1PP4P/2KR2R1 w - - bm Rxg7; id "BWTC.548"; 2r3k1/pp3p1p/7r/3pq3/8/1RPQPpP1/P6P/3R2K1 b - - bm Rxh2; id "BWTC.632"; r1br4/3n1Q2/p3p2p/1p1k4/4N2b/P3q3/1P4PP/1BR2R1K w - - bm Qh5+; id "BWTC.702"; r4rk1/p1p4p/1p1pp3/2P2p1q/2PPn1p1/1Q1BPbP1/PBR2P1P/4R1K1 b - - bm Qxh2+; id "BWTC.772"; kn1r1b1r/p1p1n3/Qp1p1p1p/P3p3/4P1pq/2PPB3/1P1N1PPP/R3NR1K w - - bm Qxa7+; id "BWTC.840"; r5kr/p3PR1p/1p4pq/4p3/8/3B4/P4QPP/6K1 w - - bm Rf8+; id "BWTC.911"; 8/2QNpKpr/1p4P1/nrBk1Nb1/1pR3p1/1n1Ppq2/8/7B w - - bm Bxb4; id "BWTC.933"; krN5/1n6/2Q5/qN6/PpK5/1P6/8/R7 w - - bm Ra2; id "BWTC.936"; 5r2/6pb/1p3r2/2pQ3B/R6p/3pPp1P/2PNk1n1/2KN1R2 w - - bm Rg4; id "BWTC.938"; 1B2K3/p2p1ppQ/N3k3/P1R1p2N/3p1b2/3P2p1/6P1/8 w - - bm Rb5; id "BWTC.944"; 8/p2Q4/N1Pp3r/K1PkBB2/R1N5/3n4/3R1p2/3r4 w - - bm Qb7; id "BWTC.950"; 3Q3B/5p2/nRN5/1np5/2k1p3/2b1R3/2B5/3K4 w - - bm Qa8; id "BWTC.952"; 8/4nQp1/6P1/N1Kpk2p/3p3P/2Npb1P1/3P4/4R3 w - - bm Ne4; id "BWTC.953"; 7K/8/8/5k1P/2P1R1NP/4Pn2/2Qn4/8 w - - bm Qd1; id "BWTC.954"; KN1R1B2/5pP1/p1p2pP1/r2Pk3/qnR4n/b6Q/2b2N1P/2r5 w - - bm gxf7; id "BWTC.958"; 4Rb1B/6q1/R7/n4pN1/2Bk4/N2p1K2/3Q4/3n4 w - - bm Re5; id "BWTC.960"; n2b4/1p2R3/8/4Q3/k7/5RK1/3B4/8 w - - bm Rh7; id "BWTC.964"; 3B4/K1pR1p1p/n5br/Q1p1k1Pp/R3N3/1B2P1nr/1pN1PP1b/1q6 w - - bm Nd4; id "BWTC.966"; 3N4/4rP2/2n5/2P1k2n/1pP4Q/1P2Nb1p/3B4/1BK1R1Rq w - - bm Qf2; id "BWTC.974"; 3N4/1p3p2/8/pR1B1Rp1/P2k2P1/1r1p1r2/1P1p1P2/Q2K2B1 w - - bm Kxd2; id "BWTC.980"; 1K6/7B/1p6/R2np2r/p1k2pQ1/1N3N2/8/1R2B1b1 w - - bm Qh3; id "BWTC.983"; 1K2krb1/1P1RP2p/7P/1n2N3/B3Q3/8/8/8 w - - bm Nf7; id "BWTC.1000";
