I want to post this game for a few reasons.
1. I'm pretty sure that we were both playing our best.
2. I got dismantled, and it was probably due to our rank difference.
3. I have no clue where I went wrong.

I played black, and lost by 62.5 points. I probably started to lose the thread at move 26.



I also want to thank Karaklis for an awesome game. I hope that I didn't offend him by playing to the bitter end. I learned a lot playing, and more importantly I was having fun.

A few ideas:

Just a few comments from my side:

Move 51 doesnt seem to achieve very much. This allowed me to tenuki. Maybe taking a corner at q18 or c18 would be better.

Move 75: Here I had expected g16 or j15.

Move 79: Playing first j16 or h13 would probably have avoided the capture and started a bigger fight.

Move 111: Not necessary to capture the three stones, they are already dead by connect-and-die.

Move 125: Too small. c12 or l15 are bigger

Your opening was quite good, but you lost ground consistently when the fighting got complicated. Your biggest problem appears to be making submissive moves, or missing good moves to which you are entitled. Don't settle for safe easy moves, look hard to find more forceful moves which give you a superior result, specially in positions where you have an advantage. (This advice applies even more at the dan level, by the way.) Examples:

31) settled for an even result when you had a chance to hurt your opponent
39) should be double hane for superior result
41) forces W to fix a severe cutting weakness and then loses sente
Q2) was sente for a long time, but you never took it (not even at move 149)
73) could play G16 sente, breaking W position and helping settle your weak group (Do you see why W could not counter with D16?)
111) wasted a full move, since W cannot save those stones
113) allowed W to break your center, when almost any move on the other side was good
