Cool idea! Perhaps we can expand it into a general topic where you paste useful posts that explain different topics - like furiten, limits, counting minipoints, etc - each under its own title?Shirluban wrote:I have copied your post and stick it under the name "Illustrated guide of waits with names".
Only two of my English language MJ books give the Japanese wait names and both only have those five simple ones (and both give Tanki as "Tan Chao" which I´m guessing is more Chinese?).Fat Dragon wrote:After Ryanmentanki the author marked 3 wait types as "name unknown". Could anybody supply these names?
More important than knowing the names is knowing the probabilities. I´ve updated my previous post below to explain these... (if you´d like to copy across again?)
Tanki - pair wait, one tile waiting for another of the same
:east :east :east :south :south :south :west :west :west :north :north :north 2-crak
wait: 2-crak
As there are four copies of each tile in the full set - and you have one of them - you are waiting for only three tiles.
Some of these might be unavailable if already discarded, in a melded set or in the dead wall so three is the theoretical maximum number.
Ryanmen - the serial pair or two-sided wait, waiting to complete either end of a chow
:east :east :east :south :south :south :west :west :west :north :north 4-dot 5-dot
waits: 3-dot 6-dot
Of the five basic waits, this one gives the highest chance of winning - you are waiting for eight tiles in total (four each of the two waits).
A hand must be won on a Ryanmen wait in order to qualify for the Pinfu yaku.
Kanchan - centre wait, waiting on the middle tile of a chow
:east :east :east :south :south :south :west :west :west :north :north 6-bam 8-bam
wait: 7-bam
You are waiting on four tiles.
Penchan - edge wait, a Ryanmen including a 1 or 9 hence only waiting on one side
:east :east :east :south :south :south :west :west :west :north :north 1-dot 2-dot
wait: 3-dot
Again you are waiting on four tiles.
Shanpon - I call it a "double pair wait", a hand with three complete sets and two pairs, one of which must become a pung
:east :east :east :south :south :south :west :west :west 8-crak 8-crak 8-dot 8-dot
waits: 8-crak 8-dot
With this one too you are waiting on four tiles but this time two each of the two different waits.
