Crossposted to 0x23mahjong, because I'm awesome that way.
A simple yaku overview sheet (2 pages), based on tenhou's yaku table. No scoring tables, no rules. Image quality sucks, because I'm too lazy to do better (sue me). Spot any mistakes just tell me and I'll fix it for the next version. Here it is.
After a certain tournament in Europe, I stayed behind and played a few games with some other people who also stayed behind. I asked them if they wanted to play with open tanyao, since I hadn't had a chance to do so for the entire day (given that the tournament was an EMA one), and I would like to play something I'm more familiar with. Two of them said okay, but when the third player joined she exclaimed, "Oh no, not open tanyao!" Or something to that effect. This made me curious and prompted me to ask why so many disliked open tanyao. I got a lot of answers, but most said the same thing: "It's too fast" or "it's too cheap" or "it's too easy!"
Given that we have an amazing tool for data mining available, I figured I might as well use it. So, with the help of Umai I got my hands on some data, sadly not presented in graphs (because graphs are awesome that way). The rest of this post will detail the specific numbers regarding Open Tanyao (and open hands in general).
