The “Impossible” Tian Yuan Tower Problem

Thursday May 27, 2010

This is the go problem on the lobby wall in the Hangzhou Tian Yuan Tower (see story below) where this year’s World Amateur Go Championship is being held. According to our guide, “it’s impossible to solve this problem” but we have faith in our readers. Send us your solution (sgf files only!) and we’ll pick a winner at random from those submitting correct answers. Bonus points for telling us the name of the problem (classic Chinese problems often have poetic names) and for the names of the famous go players engraved on the stones. Send to journal@usgo.org
