Fortress you think?

     The lovely thing about Sundays is that you can do whatever you want- no classes, no exams, no work, so I've spent half of the day watching the games from Bundesliga and from Moscow Open. Couldn't help but be amazed by the win of Dmitrii Svetushkin (2612) over Yandemirov Valeri (2427).

Dmitrii Svetushkin

The position looked like a fortress for me and it might have been, until the unfortunate 29...Rf6 move, 29...Bf6 instead would have given white some headaches. Black didn't get any chances after this mistake and white exploded the position with an elegant knight sacrifice.
