White to move and win (as the computer shows that white's advantage is at least +5). The poor human with white agreed for a draw ...

The engine was the famous Rybka. I was surprised to see how the best engine in the world keeps showing such a huge advantage for white and just gives some silly checks. :))

Well, Rybka lost at Nakamura once(bullet game) with a rook advantage. As for this position, dunno, I'll look it up myself, without rybka maybe(i don't rely on computers in this kinds of positions)

Although there are positions (mostly fortresses) that will baffle computers this isn't one of them... you're not using Rybka at full strength... all you need do is configure Rybka to use the 6-man Nalimov tablebases and it'll see this as a draw more or less instantaneously.

OK, the position is from a 15 mins game I played on ICC (with white). In the position above I offered a draw (also had less than a minute or so, but I was sure that this is a dead draw). When I analized the game, the Crafty built in the client program showed that White is winning! I took a Rybka (the free one, of course, and without tablebases) and it showed the same think :)
