I put the hand into a video to make it easier to watch, it's the 4th hand I play in the clip -

It was in a 9 player NL hold-em $1 buy in Sit n Go, I think it was a stupid move but I had top pair on the flop and at the time I couldn't think of him having anything better, but I probably should have let it go when he called the All In. I find I let myself down in situations like this too often.
How badly did I play this hand and what should I have done when?
