Insomnia

Last night I was so unable to sleep. Or I should say I slept, but was continually tossing and turning. I went to bed trying to figure out the Caro-Kann Defence from the White perspective. I found this variation that I want to use in the Panov Attack which preserves the c4 pawn by advancing it to c5.

Figuring out the move order is pretty simple in the opening and there is a little play with it. If possible if there is someone out there that can provide a little analysis, please contribute to this post. The variation I am looking at is the Gundaram (possibly mispelled) with 5...c5.
