Mahjong

Thanks I didn't know about this video series, very interesting! Now that I think about it Riichi Book 1 also mentions a rule of having optimally no more than 2 pairs, and even without any, that there's no need to worry too much about securing a pair.

Apparently favoring the shuntsu over the pair is so obvious that in the below example Chiba doesn't even consider discarding the 5pin holy shit...
