  YouRang: <patzer2: Can two Bishops win against a lone Knight?> Good question. I suppose that the intuitive answer for mere mortals is "no".

However, if you check a Namilov tablebase, it appears that almost any combination of K+2B vs K+N wins! Often, it's a win in 60-70 moves, but a win none-the-less.

In this game, the position after 83...Ng6 is relatively easy mate-in-35! :)

Following the tablebase, it appears that the strategy is just to separate the knight from the king, then trap and win the knight. It turns out that it really doesn't look that hard. I bet a decent chess player could figure it out against a computer.

  patzer2: <YouRang> Thanks for the information. Looks like it can be done, but might be difficult in some instances in the face of the 50-move draw rule.

My guess is Onischuk was somewhat familiar with the ending, or else he wouldn't have gone in for it here.
