Chess photographer Frits Agterdenbos, whose work I discovered during the Olympiad this year, is running an entirely new kind of chess quiz. Get the most answers right and you could win one of only 1000 copies of his book, "64 Schaakportretten".
This one got me stumped.
The other 15 images are on the chessvista.com site. Make sure to get your entries in to Frits by 12 midday GMT on 15 January, 2007.
