Something sharp to play against Slav +Semi slav

Need something sharp to play against slav type setups any ideas?

Very bored with my current repetoire against c6 stuff it ruining my d4 pleasure, going to have to resort to the London at this rate.

Think I have found something and the beauty is black can't really avoid it.  Some interesting games in the explorer and with an open board no all slav players will feel comfortable and otb are very unlikely to have looked at it

You don't like NF3 on move 3?

No, I know theoretically it is probably the best, I just am not keen on the white slav structures from whites point of view. Will tey the line I gave further up the page see how I get on with it

Briefly, Nf3 and Bg5 against the Semi-slav is one of the sharpest lines in all of chess. 

And there's plenty of sharp stuff for White in the Slav too. You really only need a few minutes to look at some complete games to see how sharp this stuff gets. 

If you want a book to guide you, try Lars Schandorff's Playing the Queen's Gambit. It gives some great super sharp lines against all of Black's main moves after 1.d4 d5 2.c4. Your entire repertoire against 1.d4 d5 2.c4 can be solved with a single, excellent book.
