[IGS 10k] Review request for white.

Hi everyone,

I understand that move 44 from the root tree was slack and allowed black to get ahead; during the game I thought the white corner needed to be reinforced (although playing it out during review shows that it was safe). My questions for the game, was the a reduction good enough? Was there a better way to play the reduction? If black invaded after the reduction, did white respond in the best fashion?

Thanks.
