Analysis of a 45 45 game vs kskonge

I mishandled the opening and my opponent got two very strong pawns in the center of the board. I made a bad mistake on move 19, but kskonge thankfully let me off the hook, and then returned the favor on his move 22. From there on out I was able to keep things together. 

In any case, I'll need to be very careful of this pawn structure for Black in my future games.
