9x9 is a peculiar board to play handicap. Very hard to win as white. If you’re black, just play solid and win. If you’re white…
General principles are the same: keep sente, make complicated position with a lot of weak groups, sacrifice, don’t worry.
I’d imagine to win as white you need to make a kill, so probably you need to be forceful and aggressive with one of the opponent’s groups to get thick and kill the other group.
I played a little bit of 9x9 handicap. With two handicap stones I still tried to play a normal game, but with three stones it didn’t work without special strategy. One of the things I tried is attach underneath as the first move. Worked better than usual, still hard to win though.
Maybe we should see some of your games to see what can be improved?
Why do you want to play 9x9 handicap anyway? That’s not what people usually play.
Am I stupid or KGS doesn’t let me view anything?
