I have some thought on a variation that is a bit like the Clarendon Court Defense: 1.d4 g6 2.c4 Bg7 3.Nc3 c5 4.d5 Bxc3+ 5.bxc3 f5, the main differences to the Clarendon Court are of course that white committed himself to c2-c4 early on and that black actually played Bxc3. Basically I'm wondering how white should play against this.

In a game I played as white two years ago, I probably already had a winning attack after 6.e4 fxe4 7.f3 Sf6 8.fxe4 Sxe4 9.Ld3 Sf6 10.Sf3 e6, but I feel that black could have used e5 as an outpost for his pieces by playing e.g. 8...d6 followed by Nbd7, Nf6-g4-e5 etc. - maybe he could have played for that kind of position earlier, as well.

I see that 6.h4 has been played a couple of times and that seems logical, too. In fact *a lot* moves have been tried on move 6 including g2-g4, Ng1-h3, e2-e3 and many others. 

What do you think white should do? Can he actually get an advantage?

PS: Presumably someone has come up with a name for this system, what is it called?
