It's too early for an endgame study...

I just played the following 20 +20 game on FICS. The opponent was much stronger and I was playing against the Caro Kann, which I rarely see. We reached a pretty level rook and pawn endgame with white up one pawn. Because I am not awake enough to do an endgame study just now, and because I was pretty sure I would lose if I pressed a much stronger opponent, I offered a draw. He accepted and said he thought he could draw the position anyway.

What do you think?
