How to Trick your chess opponent with a bishop sack

This match has me playing against the Alekhine's Defense. As my opponent was rated significantly higher than me, I tried something a little risky in the beginning with a bishop sack. My opponent probably should have been able to win, but I think the sack through him off guard and probably made him feel like this would be an easy win, which caused him to make some positional mistakes that I was able to capitalize on. Watch and store it in your own arsenal.
