The log is below. I used a manually built user-script from the call-improvements branch.

Is there a general strategy when it is better to keep the north tiles in the hand instead of calling kita? Sorry, I don't know much about 3 player mahjong.

If the north tiles form a triple or pair and the first hand is close to tenpai, not calling kita would be considered. At least with the double riichi hand as above, it seems to be a better choice to keep them.
