Life In 19x19

I used to drink lots of soda (cola).
Now I drink lots of coffee.
No difference.

I used to play gnugo a lot on 9x9, except for learning to avoid some of the most common beginner mistakes I don't think it helped much. If you play it more often, you'll quickly learn its particular weaknesses; like the tendency to overkill a stone, allowing you to get a huge advantage by sacrifice ...

for future reference, when a game is over - especially in the beginner's room - don't leave immediately, give it a few seconds.. your opponent might offer a review. or just ask for a review, or a few hints.
