Bellon -Petrulli 1-0 - a Queen ending

Here, as White, I ended up with a Queen and pawn ending which are often slippery and require much patience.  Unless one side already has a big advantage, (passed pawn, etc.) the player who doesn't "crack" first usually wins.  Here, I patiently waited for my opponent to make a mistake and went on to win, though I missed a few things earlier on.  Analysis by Fritz 10.
