Subject: A Mate in 9 position, plus some 'interesting' timings...

Here's a good Mate in 9, which I've tried on a selection of engines:

2n2r1k/1rqp2p1/2pR1p1p/1bP1p3/pP5R/P3P3/BB3PPP/3Q2K1 w - -

The line goes:

31. Rxh6+ gxh6 32. Qh5  Kg7  33. Qg4+  Kh7  34. Rxf6  Bd3  (or 34. Bb1+)
35. Rxf8  Bg6  36. Bg8+  Kg7  37. Rf7+  Kxg8  38. Qxg6+  Kh8  39. Rh7++

Almost all find 31. Rh6+ more or less immediately, although Hiarcs 7 would
probably play 31. Bxe5 (also winning) at blitz. Times for Mate in 9 (200MHz):

Junior 5	                     00:20
LGG 2,0		00:27
CSTal II	                     00:27	(giving a score of +34.60, not sure what
this means)
CM6000		00:30	(approx)
Hiarcs 7 (180 MHz)     01:10	"White can mate in 13", it says, and remains
content.
Genius 6	                     01:30
Crafty 16.6     	03:00
Fritz 5.32	                     11:14	Interesting...
Der Bringer               ?>30:00	Finds 31. Rxh6+ immediately -- I just love
this GUI!
