During Christmas holidays I tend to indulge in online chess playing a bit too much, wasting several hours a day that could be used to get back on track with the gazillion research projects I am currently trying to keep pushing. But at times it gives me pleasure, when I conceive some good tactical sequence. 
Take the position below, from a 5′ game on chess.com today. White has obtained a winning position, but can you win it with the clock ticking? (I have less than two minutes left for the rest of the game…)

In the diagram White is to move, after black blundered in a more or less even position by playing Qb4-d6, thinking that with his move he would take advantage of my pinned Ne5. Unfortunately for him, this opens the way to a pretty sequence. Please find the full variation leading to a completely winning position. Extra points if you do it without moving pieces on the board and in less than 30 seconds!

I will post the solution in the comments thread below tomorrow… If you need a hint, the poor position of the Nb8 is part of the problem that black is facing.
