Many thanks to Ed for Rebel XP - you're too generous! I've been playing with the new package and it's fun. I especially like the statistics that are shown as the engine searches. However I was surprised by the following position: [d]r4qrk/ppp1b1pp/3p1p2/4pPPQ/4P2P/3PB3/PPP5/1K4RR w - - Key move Qxh7+ mate in 4. This is an old position from your tactics database and one that I actually sent to Ed way back in the days of ChessMachine, which couldn't solve the position in 15 mins whereas THe King could solve it almost instantly. Ed's obviously put it in with other problems and the last time I tested it on one of Ed's engines it was solved instantly. To my amazement when I sparked up Rebel XP and set it to the combinations setting IT COULDN't SOLVE THE POSITION in 15 mins on my 1.5 GHz P4. Strange! - heavy pruning I guess - or is it a search bug. Interestingly without the Combinations option it is solved within 5 secs. Regards, Steve
