What can we learn from 9 million real hands of Tichu? It turns out quite a lot. This file provides a pivot table which gives a view into 800 combinations of starting 8 cards and tells you how often people call grand with each combination, and how often they succeed. Discussed here:
http://www.boardgamegeek.com/article/3213030. Please keep the discussion there.
But I should mention, as a quick instruction guide, that to use the pivot table, you simply click the plus/minus buttons to construct the starting hand you're interested in. You can drill down as little or as much as you want. If you don't drill down all the way to specify every field in the pivot, the fields not specified are simply rolled up (still independent). You can also reorder or take fields out of the pivot (or add dog or mahjong back in the pivot, since it's out by default after I realized it makes very little difference). The order of the fields is the order the boxes were checked on the right. So, for example, you can uncheck all the boxes (except the bottom 4, see below), and re-add the fields you care about, in the order you care about.
An important note: NEVER uncheck any of the four last fields. They (and their order) are required to make the Win% and Call% columns work. If you ever accidentally uncheck any of those, simply close (without saving) and reopen..
History:
1.1: Added 2 new fields. 1: Number of queens. 2: Whether partner passed their highest card. Both are off by default. See above for how to add.
