White has been playing poorly and let black get a whole lot of space in the corner. White tries an invasion that never should have worked but black has been drinking and places the marked stone instead of doing something reasonable. Explain to black that he's had enough. There are no ko threats. (my first problem, please comment. Also, I don't know how to indicate that the right and bottom are not actually the sides of the board)
