Thanks for posting. That was amusing; you finally got him after numerous overplays.
I think that you tried to hard to kill early in the game. He made overplays and you created weaknesses in respose. Often the best response to your opponent's overplay is to let him create a weak group and just make yourself strong nearby. Then bide your time. If there is a ko, attacking the weak group can be a huge supply of ko threats. If he creates a second weak group - and such players are prone to do so - then you can start a splitting attack between those two groups.
For a good example of this technique, I recommend looking at Magicwand vs Araban ( http://www.lifein19x19.com/forum/viewto ... =37&t=3164 ) In return for some territory, Araban allows himself one weak group over on the left early in the game. Magicwand does not attack it. He keeps his own groups strong. Then, when Araban takes a risk with a group in the lower right, Magicwand is able to start a splitting attack between two groups. The game is still undecided because Araban's groups are not all that weak and are able to fight back, but Magicwand's patient technique is worth studying.
In your game, his groups are often really weak, and if you just build your own groups strongly, you should be able to crush this guy next time. For particular examples of how to build stronger groups, Shaddy has great suggestions for moves 12 and 38.
One last disconnected thought: if you want to get past 5K, you'll need to know the basic getas. ( See http://senseis.xmp.net/?Geta, particularly example #5 ) In your game, 106 should be at E12.
