... GM Spassky spent about 5 minutes looking over the position then played 15.bxc3. 30 seconds later he changed his mind and took back the move. He then grabbed a seat, took off his sunglasses and sat opposite me. He thought out loud and several times went to move but changed his mind. He said, "This is a very interesting position. I cannot find a square." He then thought some more. After what seemed like an eternity, I suddenly thought about Bobby Fischer in 1960 and how Boris had beaten him despite being behind. I said, "Everyone here wants to beat you Mr Spassky but I would be happy with a draw." He replied, "Okay, if you want draw in such position, of course I accept." He said to the adjudicator that he needed a 5 minute break and that was that. Thanks again to everyone for their help!
A lot of it now on youtube for all to see. There's a slow stretch but the action restarts at 2:18.
very cool
