  Chessical: An effective attack on the white side of a Sicilian by Biyiasas quickly overwhelms Hug's cumbersome manoeuvering on the Q-side. The final combination is attractive:

22.Nxe6! fxe6 23.Qxe6+ Qf7 24.Qxg6+ Qxg6 25.Rxg6+ Kh8 26.Rxc6 winning three pawns

Jan-11-13  thomastonk: The position after 14... b6 is quite interesting, because of the many different aspects that appear within only a few moves: White has already a clear advantage in developement, he gets control of the open file, uses a zwischenzug, weakens the opponent's king side position and then destroys the pawn chain with a sac.

It is also a fine example to see the different types of advantages from slight to winning. Moreover one can study which lines have to be computed and how deep or flat the calculation has to be.

I found the example in "Offene Linien" by Uhlmann/Schmidt (1981), but I have added some lines in my training courses, mainly because Black has much better resources than mentioned there (e.g. 16.. Qe8).
