There are certainly weaknesses in Fruit's evaluation but I do not think that they are terrible. In this case I guess that the main problem is that fruit evaluates pawn storm that is not effective(f4 g5 h4). Here is some analysis of my favourite personality(history threshold=50) Note that it can see some advantage for black after deep search so maybe the problem is that fruit did not search deep enough(it is interesting to read opinions about the losing error of fruit).
