You enter your game and any moment you're curious to find out what the possible continuations might be in a certain pattern you select that region...
... and press the search button. GoBase will now return
all games in the collection which feature this pattern.
In this case two games were found. The matching region
of the board is indicated. Both games feature Cho Sonjin
as white. On the left against Cho Chikun as black for the
54th Honinbo title in 1999 and on the right against O Rissei
for this year's Kisei title (the 25th edition).
