Subject: Another nice position, and LGG 2.0 gets it (not Crafty 16.6 or CSTal II)

Here's another nice one, from my first game with Hiarcs 2.1 in late 94.

2r1r1k1/3q1p2/p1bp2pp/1pn1pNb1/4P3/2P2QNP/PPB2PP1/R3R1K1 w - - 0 24

White's 24th is a killer, 24. Rad1 (Black has just played 23. ...g6).

Crafty 16.6 and CSTal II both fail to get this after 30 minutes each,
preferring respectively 24. h4 and 24. Qg4, neither of which wins.

LGG 2.0 comes up trumps again:

depth=12 +0.23 a1d1 g6f5 g3f5 e8e6 h3h4 g5d8 f5d6 e6d6
d1d6 d7d6 f3g4 g8h7 g4c8 d8h4 c8f5 h7g8 e1d1 d6e6 f5h5
Nodes: 70970656 NPS: 19444015
Time: 00:00:03.65

(In fact, Black played 27. ...Rb8 in the game, but if 27. ...Rxd6
as in LGG's analysis, White should then play 28. Qg3+ and 29. Qxe5)

I only tried these three programs so far (naturally, attempts in 94/5
by Geniuses 2-4 and Fritz 3 failed) -- any offers, ...Jeremiah?
