Caro-Kann to BDG by Zintgraff

Gary Zintgraff sent me a game with his notes which I edit for space. Zintgraff wrote: "Here is my BDG [Caro-Kann to Gunderam} vs Al Fulton. It has not yet been published. Al had researched and found some German analysis [which I had not seen] that showed my 9.Nxf7 to be invalid so long as he played the correct move 11...Kd7! instead of 11...Be7? which he transposed to one move too soon. Whew! I like this game because it demonstrates how sensitive Black's defensive moves are to White's initiative and how a move which looks just fine (11....Be7?) can lead to disaster. Enjoy, Gary Zintgraff"

Thanks, Gary. White should play earlier 10.Qxc2! with the advantage as shown in my Blackmar-Diemer Theory 3 book, section 4.2. This book 3 is part of my larger volume Blackmar-Diemer Series: Books 1-4. I plan to post a BDG type game every fifth post.

Zintgraff (1839) - Fulton (1784), San Antonio Chess Club, 19.06.1999 begins 1.d4 d5 2.e4 c6 3.Nc3 dxe4 4.Bc4 Nf6 5.f3 exf3 6.Nxf3 Bf5 7.0-0 e6 8.Ne5 Bxc2 9.Nxf7 Kxf7 10.Bxe6+ Kxe6 11.Qxc2
11...Be7? [My opponent told me a week after this game that he had planned to play 11...Kd7! which was recommended in the German analysis. It appears to win for Black in all lines. I found a Tim McGrew game vs Moonshot, ICC which went: 12.Bg5 Be7 13.d5 cxd5? (Instead 13...Kc8 would have maintained Black's advantage for Moonshot, e.g. 14.Rad1 Nbd7 15.dxc6 Qb6+ 16.Kh1 Qxc6-/+) 14.Nxd5 Nxd5 15.Rad1 Qb6+ 16.Kh1 Qc6 17.Qf5+ Kc7 18.Rxd5 Bxg5 19.Qxg5 McGrew-Moonshot, ICC 1998] 12.Qb3+ Nd5? [12...Kd7! would have been much better but 13.Qxb7+ Ke8 14.Qxa8+-] 13.Nxd5 Qxd5 [13...cxd5? 14.Qh3+ Kd6 15.Bf4+ Kc6 16.Rfc1+ Kb6 17.Bc7+ Qxc7 18.Qb3+ Ka5 19.Rxc7 and mates soon.] 14.Qh3+ [If he had not resigned when he did, I had planned to oscillate my Queen along the 3rd rank two more times. Now if 14.Qh3+ Kd6 15.Bf4+ Qe5 16.Bxe5+ Kd5 17.Qb3+ Ke4 18.Qf3#] 1-0 [Notes by Zintgraff]
