;W[pg]C[This is the most common way for white to play in this joseki position.]
(;B[pd]C[However, black can also play this bumping move. This is a trick play.
If white responds in the right way, the result will be slightly favourable for white.

But be careful. There are many mistakes you can make in this position.]
