I couldn't resist posting this one, a good example of Mihai Suba's dynamic play , and I think, a good test for programs: 1r1r1nk1/q4bpp/2pb1p2/P1N1p3/P3P3/B1R1Q1PB/3P3P/5R1K w - - 1. Nd7!! Qxe3 ( 1. ...Rxd7 2. Qxa7 Rxa7 3. Bxd6 Rba8 4. Rxc6 Rxa5 ( 4. ...Bg6 5. Bf5 Rxa5 ) 5. Rfc1 Rxa4 6. Rc8 Be8 7. Bxf8 ) 2. dxe3 Rxd7 3. Bxd7 Bxa3 4. Bxc6 Bb4 5. Rb1 At this point, "the position was technically won", says Suba (suggesting that 5. a6 might have been quicker). I can't imagine there's any doubt about this. I didn't expect any program to get this easily, so I was both surprised and pleased when LGG 2.0 found it immediately, with no apparent 'waverings'! CSTal II found it at 2 seconds, but lost the plot at 21 seconds. Fritz 5.32 (in multiple mode) is still playing 1. a6 (not good for White after 1. ...Bxc5), it's been on about ten minutes now (1. Nd7 not yet among the top seven lines). Crafty 16.6 and Genius 6 hadn't found it after 3 minutes plus. (P Pro 200MHz.) Any other results? Francis
