"The Case of the Board Shaker"

Many players are just bundles of nerves and can’t help vibrating and shaking all the pieces and the table (mostly on their time, when they are most immersed in thinking). This would include GM Walter Browne. The action: Huebner often went nuts on these guys, but I for one didn’t mind that much. Igor Ivanov, a very mellow soul, would just lean back and tip his chair backwards. The result: kibitzers were always entertained when Walter cycled through postures and expressions in Zeitnot. I believe ex-WC Tigran Petrosian was also a table shaker, and an occasional leg-kicker, in his day. Complaints were not heard - Tigran strategically switched off his hearing-aid! (I believe this anecdote came from his arch-nemesis Viktor Korchnoi).
