Rendering pieces useless

I thought this was a pretty interesting game.  To be honest, I played quite poorly in the beginning, but after 29. ... Rd5 I think I had a decent position even though I was down on material.  After some maneuvering, I basically managed to render both his rook and bishop completely useless.

My rook is also static but at least it's on that eighth rank, and also my bishop has a pretty useful diagonal.  Unfortunately White ended up using most of his remaining time to think of a good move in this position, so we didn't really get to see an interesting ending.
