Well… I’ve returned from taking a short break from Go. It was the holidays, so travel helped interfere with my go playing! It wasn’t only travelling, though… I needed a break - I think I was pressing too hard and making too many over plays (or under plays…) My best games in the week or two before Christmas were the League matches, but they had their own problems.
Go is a psychological game. Obviously tactical skills are a requirement, reading skills are quite necessary, and the fundamentals are essential to the game. Given two people of equal skills or a game played at the appropriate handicap, the game is essentially psychological.
Overconfidence in your ability, at least at the 10-15 kyu level, results in disastrous overplay. I think that once I realized I grew so much stronger when I jumped from 18 kyu to 14 kyu in November to December, this was the result. I was attacking groups well, growing stronger in Life and Death, and winning a lot of equal games.
And once I realized this (see the partially lost post Dec 10th) I started losing. Why? Because I pushed the envelope just a little too hard. I made too much close contact when attacking and reckless plays. I played better in the December League finals, but this was more because I lost my confidence and played some more defensive moves.
When I realized my problems I decided a break from the game was in order. I took a week and simply started rereading “Attack and Defense.” The results of regaining attacking ability can be seen in the game I played yesterday. (VIEW) (SAVE)
I also had a fun time getting my brother on KGS 
Now I can try to teach him how to be a 18-20 kyu (From my experience, that’s about where you get addicted to go… heheh). 9×9 and 13×13 games will be best for now - only problem is that I’ve never played 13×13! I’ll have to see how different it is!
