Hi, I know that you attack for profit, so I think that move 33 stone was a mistake that a realize after the game, p10 is right direction, correct? I played a couples of games that I tried to kill and not profit, even knowing that before hand, so I want some advice when to gain profit and when to kill. Thank you very much.

Game summary: 

Hi Gustin,
My name is Leo and I play as 3k on KGS. I will have a look at your game and leave some comments to provide you with some ideas how to improve your game. It's impressive to see your development from 15k in July to 11k today. It looks like you will be single digit kye before end of the year. Maybe next year I will have to stop commenting your games. ;)

Summary:
In the beginning Black focussed a lot on building a big framework on the upper right side. This worked out quite well (although Black made a joseki mistake - move 9) but at the same time White got very good influence basically on the rest of the board. After move 14 I already feel that White has a big advantage and that Black will have a really hard time in this game.
At move 17 Black started to invade White's sphere of influence which was a good decision. Anyway White got the chance to attack Black's stones and meanwhile build his framework. A big mistake came with Black's move 27. You allowed your opponent to cut your stones and take good profit at the top.
After finalizing your framework on the right side with move 33 White invade (not sure if this was necessary). And your reaction was too passive. You only realized 3rd line territory on the right side and allowed White to build a strong group in your sphere of influence.
With move 53 Black started a last "do or die" attack. It failed (which is okay as White's group already was quite strong at that point) and the game was decided.

From my perspective there are two major things to learn from this game:
- Do not unnecessarily allow your opponent to split your stones. This happened two times in this game (move 27/28 and move 43/44). And it will almost always result in an advantageous situation for your opponent.
- After building a good formation (and the one you built on the right side in this game was superb) you must not allow your opponent to easily invade into your territory. The moves 35, 37, 41 etc. were way too passive. If White invades in a situation like this you have to attack these invading stones as severly as possible.

I hope you will enjoy the review. Good luck for your next games!
