Subject: BS 2830 Problem #5 --> More yammering about it:

Author: Dann Corbit

These are the analysis ideas from the chess programs for the Rxe6 trace:
2r1r3/p3bk1p/1pnqpppB/3n4/3P2Q1/PB3N2/1P3PPP/3RR1K1 w - - pv Rxe6 Qxe6 Re1 Qf5
Qxf5 gxf5 Bxd5+ Kg6 Bd2 Kg7 Bb4 b5 Rc1 Nb8 Rxc8 Rxc8 Nh4;
2r1r3/p3bk1p/1pnqpppB/3n4/3P2Q1/PB3N2/1P3PPP/3RR1K1 w - - pv Rxe6 Qxe6 Re1 Qf5
Qxf5 gxf5 Bxd5+ Kg6 Bf4 Kg7 Kf1 h5 Be6 Rcd8 d5 Ne5 Nxe5 fxe5 Bxe5+ Bf6 Bc7 Ra8
b3 Bc3 Rd1;
2r1r3/p3bk1p/1pnqpppB/3n4/3P2Q1/PB3N2/1P3PPP/3RR1K1 w - - pv Rxe6 Qxe6 Re1 f5
Qg3 Qxe1+ Nxe1 Red8 Qd3 Bf6 Qa6 Ne7 Qxa7 g5 h4 gxh4 Nf3 Kg6 Bd2 Rc7 Qa6;

And this is the output for Qh3:
2r1r3/p3bk1p/1pnqpppB/3n4/3P2Q1/PB3N2/1P3PPP/3RR1K1 w - - pv Qh3 Rh8 Re2 Nd8 Nd2
Re8 Ne4 Qd7 Nc3 Nxc3 bxc3 b5 d5 Bxa3 dxe6+ Kg8 exd7+ Kh8;
2r1r3/p3bk1p/1pnqpppB/3n4/3P2Q1/PB3N2/1P3PPP/3RR1K1 w - - pv Qh3 Rh8 Bc4 Na5 Ba6
Rc6 Rc1 Rxc1 Bxc1 Qd7 Bd3 Bd6 Be4 Bf8 b4 Nb3 Bb2;
2r1r3/p3bk1p/1pnqpppB/3n4/3P2Q1/PB3N2/1P3PPP/3RR1K1 w - - pv Qh3 Rh8 Bc4 Qd7 Rc1
Rhd8 Bb5 a5 Bg5 h5 Bd2 Rc7 Re4;

By analyzing at the first point of disagreement, more information may be
obtained.  I am going to analyze after:
2r1r3/p3bk1p/1pnqpppB/3n4/3P2Q1/PB3N2/1P3PPP/3RR1K1 w - - pv Rxe6 Qxe6 Re1 Qf5
Qxf5 gxf5 Bxd5+ Kg6;
has been completed
[D]2r1r3/p3b2p/1pn2pkB/3B1p2/3P4/P4N2/1P3PPP/4R1K1 w - -

and also this:
2r1r3/p3bk1p/1pnqpppB/3n4/3P2Q1/PB3N2/1P3PPP/3RR1K1 w - - pv Rxe6 Qxe6 Re1 f5;
[D]2r1r3/p3bk1p/1pn1q1pB/3n1p2/3P2Q1/PB3N2/1P3PPP/4R1K1 w - -

as well as after:
2r1r3/p3bk1p/1pnqpppB/3n4/3P2Q1/PB3N2/1P3PPP/3RR1K1 w - - pv Qh3 Rh8 Bc4;
[D]2r4r/p3bk1p/1pnqpppB/3n4/2BP4/P4N1Q/1P3PPP/3RR1K1 b - -
and after:
2r1r3/p3bk1p/1pnqpppB/3n4/3P2Q1/PB3N2/1P3PPP/3RR1K1 w - - pv Qh3 Rh8 Re2;
which should give greater depth.
[D]2r4r/p3bk1p/1pnqpppB/3n4/3P4/PB3N1Q/1P2RPPP/3R2K1 b - -
