Let me guess that the evaluation was slightly different than public fruit and
the score for 9.Nc3 was 0.00

Let me guess that fruit could play 9.Nbd2 with different contempt score.
Am I correct?

Note that it seems that this mistake did not change the place of fruit in the
tournament(second place).

Note also that if there are people who put their money on gambling that fruit
will not finish in the first 4 places based on your words before the tournament
then you need to apologize.
