This purpose of this post is to show you the result of the opening’s analysis of our previous lesson. This is one of the reasons that all the moves are taken from the ICOfY database instead of my own database.
LolliThe result is an Opening analysis of the Lolli Attack. You can compare it with the opening report that we have created before, with the most exhaustive analysis of this opening on the Web by Michael Goeller on his very nice looking website and with the analysis that you have done by yourselves. I suppose that the best method will be to generate your own lesson based on for example the ICOfY database and add your own comments to it. This time I didn’t add any personal, other people’s or general knowledge about this opening to the post, because the main purpose is to show how you can make your own analysis (probably even for another opening).
As we have seen in the automatically generated opening report there are at least 14 move orders reaching the position after 1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Ng5 d5 5.exd5 Nxd5 6.d4 exd4 7.O-O and Black has least eleven alternatives to continue, but only two of them are frequently played and I will limit myself to the three most important ones in this post, but feel free to add the missing continuations to your own chess material. Adding them to this post will make the post more dificult to read. Maybe even now the post is rather difficult to read, because of the fact that I show an example game for each continuation.
White to move
1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.Ng5 d5 5.exd5 Nxd5 6.d4 exd4 7.O-O f6
( 7… Be7 is the most frequently played move, almost always followed by 8.Nxf7 Kxf7 9.Qf3+ ( 9.Qh5+ is another frequently played move, but 9.Qf3+ is better. But the advantage for White is enough to win the game. A nice illustration is given in the following continuation 9…g6 10.Bxd5+ Ke8 11.Qf3 Qd6 12.Bf4 Ne5 13.Qe4 c6 14.Bb3 Bf6 15.Re1 Bf5 16.Bxe5 Qc5 17.Qxd4 Qe7 18.Nc3 c5 19.Bxf6 cxd4 20.Rxe7+ 1-0 Vliembergen Marina van – Einarsen Rune / ( 3 ) , 2005 ) 9… Ke8 ( 9… Bf6 10.Bxd5+ Be6 11.Bxe6+ Kxe6 12.Qb3+! is the best move, followed by 12…Qd5 as in this example game 13.c4 dxc3 14.Re1+ Kd6 15.Rd1 Nd4 16.Qxd5+ Kxd5 17.bxc3 Rhe8 18.cxd4 Bxd4 19.Be3 c5 20.Bxd4 cxd4 21.Nd2 Rac8 22.Nf3 Rc4 23.Kf1 Rec8 24.Rd2 Ra4 25.Rb1 b6 26.Rbd1 Rcc4 27.h4 g6 28.g3 h6 29.Kg2 b5 30.Re1 a6 31.Re5+ Kd6 32.Re8 Kc5 33.Rg8 Rc3 34.Nxd4 Rxd4 35.Rxd4 Kxd4 36.Rxg6 Ra3 37.Rxh6 Rxa2 38.h5 b4 39.Rb6 Kc3 40.h6 Ra5 41.g4 1-0 Urban A – Kallenberg E / ( 2 ) , 1978 ) 10.Bxd5 Rf8!! The best move, but completely ignored by M. Goeller. 11.Bxc6+ bxc6 12.Qxc6+ Bd7 and now I suggest to play 13.Qc4 A nice continuation showing a mate threat 13… c5 14.Re1 Rc8 15.Bg5 Rf7 16.Rxe7+ Rxe7 17.Qg8# 1-0 Hatarik Robert – Grienitz Kai Oliver / ( 1 ) , 1999 )
( 7… Be6 8.Re1 Qd7 ( 8… Be7 isn’t any better 9.Rxe6 fxe6 10.Nxe6 Qd6 11.Bxd5 Bf6 12.Na3 Ke7 13.c4 a6 14.Bf4 Ne5 15.Nxd4 g6 16.Qe2 c6 17.Nf3 cxd5 18.Nxe5 1-0 Sharafiev Azat – Mingachev Mansur / ( 8 ) , 2004 ) 9.Nxf7 Kxf7 10.Qf3+ Kg8 11.Rxe6 Rd8 ( 11… Ncb4 12.Re5 c6 13.a3 Re8 14.Rxe8 Qxe8 15.Qd1 b5 16.Bf1 Na6 17.a4 Ndc7 18.Nd2 Nc5 19.axb5 cxb5 20.Rxa7 Qb8 21.Ra1 N5e6 22.Nf3 Bc5 23.Qd3 h6 24.Bd2 1-0 Medveski Mike – Berrisford Shaun, 1999 ) 12.Qe4 h6 13.Bd2 Rh7 14.Na3 Kh8 15.Re1 g5 16.h4 gxh4 17.Qxh4 Be7 18.Qh5 Nf6 19.Qf5 Ng8 20.Bd3 Bb4 21.Qxh7+ Qxh7 22.Bxh7 Bxd2 23.Rd1 Kxh7 24.Rxd2 Rd5 25.c3 Kg7 26.Nc2 Kf7 27.Re1 1-0 Harding Timothy David – Knol Everdinand, 2000 )
7…f6 seems to be the best move according to Crafty, the database and Michael Goeller, but he also mentions that no real games can be found and limits his analysis to some quotes of Fritz and Heisman. Even in the free available database that we are using today we will find eight recent games. 8.Nc3
( The alternative 8.Re1+ is considered almost equal by Crafty after 8…Be7 9.Nf7 Kxf7 10.Qh5+ Kf8 ( But it seems that most players will be tempted to play 10…g6 11.Bxd5+ Ke8 12.Qf3 but even in this line White only has a small advantage, which may be enough as shown in the game 12… Qd7 13.Bh6 Ne5 14.Qe4 c6 15.Bb3 Kd8 16.f4 Bd6 17.fxe5 Bxe5 18.Nd2 Re8 19.Qd3 Qf5 20.Qxf5 Bxf5 21.Nf3 Kc7 22.Nxe5 fxe5 23.Bg7 Kd6 24.Bf6 c5 25.a4 Rac8 26.Bf7 Rf8 27.Bxe5+ Kc6 28.Bb3 h5 29.a5 b6 30.axb6 axb6 31.Ra7 b5 32.Bf7 Ra8 33.Rc7+ Kb6 34.Bd5 Bxc2 35.Rc6+ Ka5 36.Rxc5 Kb4 37.Rxc2 Rae8 38.Bg3 Rd8 39.Bf3 Kb3 40.Rd2 Rf7 41.Red1 Rfd7 42.Bc6 Ra7 43.Bxb5 Kb4 44.Bd3 g5 45.Rc1 h4 46.Be1 g4 47.Re2+ Kb3 48.Bc4+ 1-0 Verges Joerg – Hubel Katrina / ( 7 ) , 1999 ) )
7…f6 8.Nc3 8… dxc3 ( 8… Nxc3 9.Bf7+ Ke7 10.bxc3 +- as in this game with a very nice mate 10…fxg5 11.Qf3 h6 12.Re1+ Kd6 13.Qd5# 1-0 Moessle Harald – Thos Jens, 2001 ) 9.Bxd5 fxg5 10.Re1+ Be7 11.Bxg5 ( Even 11.bxc3 may be playable, but the chances seem to be equal here 11…Qd6 12.Bxg5 Kd8 13.Bxc6 Bxg5 14.Qh5 Qxc6 15.Qxg5+ Qf6 16.Rad1+ Bd7 as in the game De Boer Willem J – Bosmans Joost L / 1-0 ( 42 ) , 1997 ) 11… cxb2 12.Bxc6+ bxc6 13.Qxd8+ Kxd8 14.Bxe7+ ( as in 14.Bxe7+ Ke8 15.Ba3+ Kf7 16.Re7+ Kf6 17.Rb1 Rd8 18.Rxc7 Be6 19.Be7+ Ke5 20.Bxd8 Rxd8 21.f4+ Kxf4 22.Rxc6 Bd5 23.Rc5 Be4 24.Rb5 Bxc2 25.Rf1+ Ke3 26.Rxb2 Rd2 27.Rf3+ Kd4 28.Rf7 Kc3 29.Rbb7 Be4 30.Rfc7+ Kd4 31.Rd7+ 1-0 Freytag Walter – Rosner Dirk / ( 1 ) , 2003 )
Next lesson we will create a New opening report based on the functionality that ChessDB is offering, but only based on the most important games.
