I have long stated that long strings are less rulesensitive. (See my post about [Rulesensitivity according to length of string](https://getsatisfaction.com/eternagame/topics/rulesensitivity_according_to_length_of_string)).

But there are exceptions. I think this pattern will be bad in all lenght of strings. I will like a strategy for strings that says:

Ban three sameturning pairs of the same color (no matter which of the three basepairs), if at the end of the string or starting from a multiloop. This pattern is doomed. Give -1 pr. each. Here are a few examples from our bot:
