Thinking to force the exchange of queens, Black played ... Qb6? What happened next?
White has just captured a Black pawn on c7. The pin on the bishop looks worrying, but White can escape the pin with Rc8+. Sadly, however, Black can win material. Beware, this problem is harder than usual, and the main line is nine moves long.
