 The first 40 moves of an interesting game against the Chess.com's iphone ap at level 5.  The computer schools me by taking the only open file, and I eventually school it back by capturing the file and taking it's dominated knight.

Lessons learned:

- Open files are deadly important.

- Accurate defense can save you a lot of headaches

- Just because you castled kingside, doesn't mean your king shouldn't go for a walk to the queenside.  Think outside the box and consider all the posibilities.
