Bobby Fischer's psychological state questioned at Curacao by those present. The causes and condition are quite drastically different from the reports Bisguier and Donner, et al would have us to believe. No reports of behaviors such as “stomping on crabs and insects” either.
They were psychologically assessing Bobby.
Very tame analysis.

“With the first quarter of the tournament now over, chess observers still give Fischer a chance to win despite his three losses if he wins his adjourned game with Keres. The reasons advanced for his slump range from illness—he has a bad appendix—to psychological problems arising from the fact that he did not lose a game in two previous tournaments.
The four losses by Tal were shrugged off, however, with the comment: “He's a speculator and his gambles aren't paying off.”
