"Der Bringer" ( http://www.reubold.onlinehome.de) gets 80 out of 90 right in 1
minute on Athlon 1.33.

Unsolved Positions:

8/1p2r1kp/1p1R2p1/4qp2/1P6/P1p1P1P1/5P1P/3Q2K1 w - - am Rxb6; id "arasan.23";
1r1q2k1/pBp3p1/4p2B/4br2/3n2Q1/6P1/P4P1P/R4RK1 w - - bm Be4; id "arasan.58";
2rq1rk1/1p2b1pp/4b3/3npp2/8/2BPP1P1/2QN1PBP/1R3RK1 w - - bm Nc4; id "arasan.82";
5rk1/5ppp/n7/p6n/2rBP3/q2P1N2/3Q1KPP/7R w - - bm Ra1; id "arasan.125";
6rk/1R4n1/p3p3/6R1/2Pp1n2/1P6/P5PP/6K1 w - - bm Kf2; id "arasan.137";
r1b2rk1/pp3pp1/4p2p/2ppP1b1/3Pq3/2P1PNP1/PP2Q2P/R3KB1R w KQ - bm Nxg5; id
"arasan2.19";
1r4k1/p2R1pp1/4p2p/3b4/1P2q3/P4N2/5PPP/3Q2K1 b - - bm Qg6; id "arasan2.21";
8/1P6/n6p/p5k1/5p2/5K1P/2B5/8 b - - bm Kf6; id "arasan2.33";
2r1r1k1/pbnqppb1/5npp/1p1P4/1P1P1B2/Q1N2BN1/P4PPP/1R2R1K1 w - - bm Be4 Nce4; id
"arasan2.36";
6b1/1p4P1/3k4/p6p/P1P1K2P/1P4P1/8/8 b - - bm Bh7+; id "arasan2.39";

Cooks found:

1r4k1/p2R1pp1/4p2p/3b4/1P2q3/P4N2/5PPP/3Q2K1 b - - bm Qg6; id "arasan2.21";

I don't think Qg6 is the best move - better is 1...Rc8 2.Ne1 Rc3 3.Rd8+ Kh7
4.Rd7 Rxa3 5.Rxf7 Qe5 -+ ; Bringer's suggested ..a5 doesn't look worse than Qg6
either.

6b1/1p4P1/3k4/p6p/P1P1K2P/1P4P1/8/8 b - - bm Bh7+; id "arasan2.39";

This one looks broken. It probably started as "am Kc5" but Kc5 doesn't lose
anyway ; also Ke6 and Ke7 seem to be just as good as Bh7+,too. Am I missing
something?

A very nice testsuite with lots of hot tactics.

Regards,
pete
