I just realized that my computer was analysing with my screensaver on and other
programs on the background. And I just deactivated my screensaver and loggef my
wife out of Windows XP Prof and retarted it. What a difference now all my top
programs agree with this variation.
1... Ne5 2. Rxe5 Rxf3 3. Rd5+ Nd4 4. Bxd4+ e5 5. Rxe5 Kg7 6. Re7+ Kh6 7. Rxc7
Rf2 8. g4 Rxd2+ 9. Kc3 {[%eval 850,19] })
2)} 1... Nd4 2. Bxd4+ e5 3. Nxe5 Nxe5 4. Rxe5 Qb6+ 5. Bxb6 Rxf3
6. Bd4 {[%eval 891,15]} {Fritz 8:} Rg3 7. Re8+ Kf5 8. e4+ Kg4 9. Be2+ Kf4 10.
Be5+ Kxe4 11. Bxg3+ Kd4 {[%eval 956,12]})
1...Ne5 2. Rxe5 {[%emt 0:00:04]} Rxf3 { [%emt 0:00:13]} 3. Rd5+ {[%em 0:00:00]}
Nd4 {[%emt 0:00:26]} 4. Bxd4+ {
[%emt 0:00:00]} e5 {[%emt 0:00:07]} 5. Rxe5 {[%emt 0:00:00]} Qxe5 {
[%emt 0:00:11]} 6. Bxe5+ {[%emt 0:00:02]} Kf5 {[%emt 0:00:45]} 7. gxf3 {
[%emt 0:00:00]} Bh5 {[%emt 0:00:11]} 8. Bd5 {[%emt 0:00:05]}
This is the final position:
[D]4R3/5p2/6b1/6p1/3k4/6B1/1K1PB1P1/8 w - - 0 12
