Grunfeld DefenseI'm interested in analysis of games in the Grunfeld (for White side), with
the following move order/position: 1.d4 Nf6 2.c4 g6 3.Nc3 d5 4.Nf3 Bg7 5.Bg5!? If anyone can direct me as in the idea of this line and some games, it would be much appreciated. Leopold |

Grunfeld DefenseThanks Matt,
I was playing the Bf4 lines with mixed results. Here's a nice end-game swindle I pulled in the National Open a few months ago with this opening.

The fatal move, played a little too quickly. 63.Bxf4! Bxf4 64.Kg1 h5 65.Kh1 1/2-1/ Since I only knew the first five moves of the opening, I decided to try and find a solid but not played very often variation of the opening. Thus my reasoning for my inquest. Leopold "mdamien" wrote in message . .. "King Leopold" wrote in message ... So, No one who wants to comment on this line??? "King Leopold" wrote in message ... I'm interested in analysis of games in the Grunfeld (for White side), with the following move order/position: 1.d4 Nf6 2.c4 g6 3.Nc3 d5 4.Nf3 Bg7 5.Bg5!? If anyone can direct me as in the idea of this line and some games, it would be much appreciated. Leopold At one point I was considering this line, but opted instead for Bf4 lines in order to reduce the size of my repertory (thinking in terms of transpositions). I was already playing a somewhat offbeat Bf4 against the KID. So ... can't offer too much insight into Bg5, but you'll find plenty of files if you google on "Gruenfeld PGN Bg5" Matt |

... Thanks Matt, I was playing the Bf4 lines with mixed results. Here's a nice end-game swindle I pulled in the National Open a few months ago with this opening. Nice swindle -- thanks, I enjoyed it. Matt |
