Winckelmann-Reimer Gambit - 6.Nf6

1.e4 e6 2.d4 d5 3.Nc3 Bb4
4.a3 Bxc3 5.bxc dxe 6.f3 Nf6

A very effective line for white is 7.exf Nxe4 8. Qg4 Nf6 9. Qg3. White now has a very smooth development with the knight going to f3, the white squared bishop to d3 and castles. This line tends to lead to positions similar to the gambit accepted. As with the gambit accepted white usually mounts a very potent attack.
However after 8...Nxc3 things are not so clear. I have added some games with this line and some analysis by Konowski and winckelmann supplied me by Winkelmann.
