Chess: The dangerous Boor attack 5.f3!

1.d4 d5 2.c4 c6 3.Nc3 Nf6 4.cxd5 cxd5 5.f3 Nc6 6.Bf4 Bf5

This is the most critical position for 5.f3. In fact white has only one good move in the position, and if he could not play this move it is bad, but 7.e4!



7.e4




There is one tactical reason that makes this work for white, and that makes this a decent position.

I have one game in my database with 7.- Bg6, but that game is a bit suspect, the most natural response is 7.- dxe4.


7...dxe4 8.d5




Now white is doing okay.
There is a lot of exciting possibilities from this position, I do play this occasionally, I played it in a game today, that game is not really worth to show, since my opponent made a lot of blunders from here.

8.-Nb5

This was the start of the blunders
9.Qa4+ Qd7 10.Bb5 Nc6 was the continuation and he was just dead lost, I had thought 10.-Nd3+ with a complicated game, but I evaluated white as being better for white.
