  tpstar: How did we ever live without computers. On the rare 6. Qe2!? Nxc4 7. Qxc4 Fritz has the very practical suggestion 7 ... Qxd5 which I never looked at twice due to 8. Qxc7 and f7 is threatened. But Black has 8 ... Qxg2 forking Rh1 & Ng5; 9. Qxe5+ Be7 10. Rf1 Bh3 is already decisive. Lots of improvements for both sides here, but I missed a clear piece win (20 ... b5 21. cb Bb3) which would have shortened matters considerably. A previous one was Knights Over Bishops A Anastasian vs P Nikolic, 2001 and this was Bishops Over Knights; even though the Pawn formations became blockaded, his Knights had no scope.

  tpstar: Fritz 7 Deep Position Analysis [20MB]:

7. Qxc4 Qxd5 8. Qxc7 Qxg2

1) 9. Qxe5+ Be7 10. Rf1 h6 11. Qg3 Qc6 12. Nxf7 [-3.37/13]

2) 9. Qxf7+ Kd8 10. Rf1 Qxg5 11. Nc3 Qg2 12. Ne2 [-3.50/13]

<Where is my mind> Congratulations on your nice win. However, I am embarrassed to admit that I missed how the Ng5 covers h3, so I ran it through Fritz to find us a better line for next time. =)

In (1), note 12. Nf3 Qe4+ 13. Kd1 Bg4 wins.

Sep-01-06  Where is my mind: <Tpstar >Thanks for the update on the 7...Qd5 line.

  tpstar: <Where is my mind> This line is supposed to be rare, yet I faced it 2 days in a row. #1 was the Queen trade where my KN & QB quickly attacked their Queenside, slowing White's development and eventually snatching the Pa2. #2 was (2) which won easily.
