I promised you some tips on capturing things. Well this is another one :)
The idea is very simple. If you atari a stone, your opponent can usually save it (unless he’s really distracted). If, however, you atari two different stones with one move, your opponent can save only one and you get to capture the other.
Black to play
This is an easy concept but important to keep in mind whether attacking or defending. I always caution beginners playing three diagonal moves (double hane).
It tends to get cut apart when left unprotected, just because there are so many stones to atari. However, DO NOT disregard this move completely. Once you learn to read out the cuts it can be a very powerful move when applied correctly. Only do it if you can visualise what will happen when your opponent cuts :).Let me get back to this one later
