WCCC-2017 Leiden: Komodo wins in absence of Stockfish

IGCA's long criticized old championship has been held in Leiden once again with an accelerated tournament format.

Most strongest engines like Stockfish, Houdini,Gull were not participating, thus it was easier for Komodo to win a second time after 2016, though the victory didn't come as easy as expected against Jonny and Shredder, the two serious competitors. Play-offs were played to select the champion.

WCCC is nothing but a small sized tournament to me after all. Although there are interesting games, it's difficult to generalize the result. The only thing i appreciate here is that people involved in computer chess programming meet each other, so there's a social benefit, not just bits and bytes.
