Okay, so any of us who have played go very long run into this all the time, you play a decent game and its about even and then at the very end someone plays the 3,3 right in the middle of your territory. Egadz.
fear no more today I will take you step by step and show you how to kill the ugly beast that has landed in your hometown. HOWEVER this will not work at the beginning of the game because you need a large influence in the area in order to make sure he cannot escape. Role film Jerry.
THE KILLING POINTS
Number 4 on the left diagram is the killing move, after this black must prevent white from making 2 eyes
it can be difficult but if you think it through you can kill white.
On the right diagram move 2 does the same thing.
Knowledge is power! Test it out in some of your games till you get it down pat. soon people will be to afraid to play the 3,3 at all against you
Some simple suggestions
1. make sure white cannot escape through the top
2. don't let him get 2 eyes in the corner
3. don't play s5 or s4 in the beggining of the game or white will end up killing most of you and getting a large base
