Mar-20-12  Eduardo Bermudez: Castro won to Tigran Petrosian in the same tournement, IZT 1976 !!
Apr-12-15  Eduardo Bermudez: 23.Qb6 !!!
Apr-15-15  Eduardo Bermudez: The recently deceased Oscar Castro won the same year, 1976, Petrosian, Geller and Larsen, three top ten: 3,6 and 9 of the world at that time. The equivalent today to beat Kramnik, Grishuk and Topalov for a player 300 ELO points below them !!
Apr-15-15  Howard: Chess Life & Review analyzed this game back in its excellent coverage in the event, in 1976. Pal Benko remarked that at one point, Castro offered a draw to Geller but Geller turned it down for two reasons:

First, Geller had not started the tournament very well so far.

Second, Geller no doubt had assumed that Castro would be a rather easy point for him.

Obviously, he had reason to regret not taking the draw.
