Richard Taylor: I play the Nimzo and I find that 4 f3 is hard to get around. I played the main line... e.g.[Event "Notrh Shore Open 2010"]
[Site "NSCC, Northcote, Auckland"]
[Date "2010.10.10"]
[Round "4"]
[White "Luke Li"]
[Black "Richard Taylor"]
[Result "0-1"]
1. d4 Nf6 2. c4 e6 3. Nc3 Bb4 4. f3 d5 5. a3 Bxc3+ 6. bxc3 c5 7. cxd5
I am considering trying now 7. ... exd5 as although I won this I lost another game after 12. Bb5 which I thnk is better for White, and also there is a line where White sacrifices a piece on d5 for passed pawns etc
7. ...Nxd5
8. dxc5 Qa5 9. e4 Ne7 10. Be3 O-O 11. Qb3 Qc7 12. Nh3 Nd7 13. Bb5 Nxc5 14.

I think 12. ... Nc6 is better but 15. ... a6 seems better also.
I've seen that Nh5 idea in game also.
