Today I’m giving you a taste of the newest fuseki research that Japanese professionals have done! This fuseki pattern has been carefully developed and tested out by several professionals in secret, to be used to utmost efficiency in tournament games against China and Korea.
Black 1, a stone at the 7-5 point, is a relatively new move. Given that white will likely not want to jump directly into black’s plans by approaching the upper right corner, white 2 in the lower left corner is the most predictable white move. Black then occupies a second 7-5 point with black 3, and finally makes a corner enclosure in the upper right corner with black 5. This is a very fast-paced way of playing for black, emphasizing the centre of the board, and aiming to create a huge framework one way or another.
If black gets the chance, he’ll like to play the move of black 7 in the upper right corner. That creates pretty much a perfect balance in this area; it’s almost impossible for white to live in the corner, so black can expect some profit as well as influence this way.
White’s attempts to counter black’s opening are still being researched. Taking the 3-4 point in the upper left corner with white 6 is a plausible-looking idea, after which black will pressure white with black 7. White 8 and black 9 are a natural continuation. White 10 prevents the black corner approach from the right side, which would create an enormous black moyō. Black 11, then, prevents a white sanren-sei on the lower side while increasing black’s presence in the centre. The game is probably still even, but black can be optimistic about the future.
In insei games, we have tried out something like black 1-3-5 here. Black’s triangular formation is certainly interesting, but seems to lack the elegance of black 1-3-5 in the very first diagram. This way of playing isn’t recommendable.
One way for white to continue is to approach the upper left corner with white 6. Black may answer with the keima of 7, which leads to a familiar-looking joseki sequence up to black 21. White 22 is again to prevent a black approach stone on the left side, after which this time black will switch to the right side with moves like black 23 and 25. This black moyō is still wide open, while white has already made some good profit.
Now then, who feels like testing this black opening out in their games?
