~*~ PROBLEM OF THE WEEK -- Can YOU find it? ~*~

Posted by your club treasurer, RUIXUAN (4 dan!!)


G'day, fellow travellers of the 19x19 grid!!! I am your host, RUIXUAN -- ANU Go Club treasurer, and (not to boast, but I WILL) a solid AMATEUR 4 DAN over the board!!! Every week I post a position, straight off my own goban, and this week's shape has been giving people GRIEF at the club table!!! So here it is, no tricks, no fine print: WHITE TO PLAY, AND WHITE KILLS THE WHOLE BLACK GROUP. Not "reduce." Not "seal in." KILL!!! I have watched strong players walk straight past the move that does it. Study the diagram carefully before you scroll on!!!



THE POSITION

In words, for anyone using a screen reader or who just wants it read out: White has an unbroken wall across the top of the diagram, row nine from column A to column E, and a second wall running straight down column E from row nine to row six. White also has a lone stone at A eight and a lone stone at A one, plus a small tucked-in cluster at B five, D five, C four, D four, and C three, sitting inside Black's shape. Black fills the rest of the corner around that cluster: columns B and C from row two up to row eight, with outside stones at A seven and A two, and a Black wall along row eight and row seven. The star point at D three, marked with a star rather than a stone, is an empty intersection. It is White's move, and the question I am putting to you is this: is there a single White move, anywhere on this diagram, that kills the entire Black group?

I will tell you now: the answer is ONE move, and it is not where you think!!! I have had 1 dans and 2 dans stare at this for ten minutes and reach for the wrong side of the board every time. Mail me if you find it and I will put your name on this page!!!

SEE THE ANSWER (only if you have REALLY tried!!)
