Is this line of the Grunfeld playable for White? So, I was playing this line of the exchange variation of the Grunfeld: 1. d4 Nf6 2. c4 g6 3. Nc3 d5 4. cxd5 Nxd5 5. e4 Nxc3 6. bxc3 Bg7 7. Bc4 c5 8. Ne2 O-O 9. Be3 Nc6.

[Fen "r1bq1rk1/pp2ppbp/2n3p1/2p5/2BPP3/2P1B3/P3NPPP/R2QK2R w KQ - 0 10"]


In my computer's opening book, the only recommended move for White is 10. O-O.

However, I want to know whether 10. dxc5 is playable?
The problem with this line is that this is exactly what Black is hoping for.

You give the center to "win a pawn", but Black has several compensation : first of all the black bishop on ...Bg7 is now very strong. Also with ...Qc7 follow by ...Rd8 black will win the d-file. If Black want then they can easily win back the pawn by the following plan : ...e5, ...Bf8 and ...Bxc5.
