ok i like this opening as white

I like the Kan, but white just has so much play. So I like to try to find a nice blend with the Taimanov just in case white doesn't understand the theory. I think 5... Qc7 6...Nc6 then 7... b5. Then without the annoying 8. Nxc6, black can have a comfortable game, and even if white does play it, black can still create dynamic complicated positions such as bishop vs. knight and light square domination against white's advantage in space and active pieces. 

ok this is officially my new opening...

I gave up the Kan in part because of this variation -- black scores well, but I find it boring compared to the complications of 5. Bd3.
