(Komi changed from 0.5 to 7.5 for reviewing)

This went quite well in the beginning, but at the end I showed my greed and tried to capture the uncapturable. If it was a regular komi game I would have lost a won game.

I played a pseudo joseki in the lower left (the clamp is not possible in this position), but it was not punished by my opponent. I often get away with lackluster (pseudo seki for example) moves in my games in general.

Funny game. Both players missed many opportunities, but I managed to save a few points (thanks negative komi) for me till the end.

Crazy club game: After my silly 20 points mistake in the oppening (upper left), i had a lead of about 33 points in the middle game, but blundered again and in the end the game was close again but my friend TK took the win.

Look at the graph :shock:

(Decent lack of reading on my part :-). In the upper left I was following the general rule add one stone instead of reading. Took note: It is not always good, to add one stone to increase liberties of a captured stone. Damn, read at least 3 half moves deep ;-))

Komi 0.5 > 7.5 for reviewing purpose

What I have to learn:

Move 34: Always look for captures in a net if a ladder seems to be not working.
Move 60: Dont toss away liberties by making unnecessary exchanges
Move 108: Instead of just extending, check if a one space jump is possible (playing at the important point at once).
I have to better control my greed.

short fighting game

you shalt not pincer me two space high
for I

My mediocere fighting skills did not save me, but the greed of my opponent did it this time.

Today I caught a cold and I am not in the mood for another game. Let us do a detailed review of this one game instead. I prefer to analyze won games because there are still enough difficult to spot mistakes in a won game to learn a lot and in lost games most of the times there are just embarrassing blunders that should have been avoided with a little bit care in the first place.

In the light of the great AI and Joseki debate I recently changed my playing style from mainly bot inspired 3-3 invasions to exploring other options like attach and extent or the traditional approach move. While I like to win go games, the real pleasure for me is exporing the endless possiblities on the goban, and in this light a little bit of variety can't hurt anyways.

I am black in this game:

There are over 3000 pro games with the approach move in my database. The white pincer was only played 14 times and only 3 pros choose the 3-3 point in response.

Black should probably play directly at a. But because white is going to answer traditionally the 3-3 invasion was also good for black.

I had good feeling after 29 and the bots agree and think black is ahead about 3 points.

And by the way this is good counter example against the flawed (like all heuristics) heuristic: Play at the biggest open space.
