Analysis of a mahjong hand
Posted: Wed Oct 11, 2017 7:38 pm
Had this multiple wait hand recently and although I didn't see all the possibilities during the game, it looked interesting enough to analyze afterwards. Game was East round only.
It was time to make a discard and call riichi
There were 2 choices. The or the .
Discarding the 6bam would leave me with a wait of .
Discarding the 4dot would leave me with a wait of .
Coincidentally, if all are available, both have a 13 tile wait.
The all yield riichi/tanyao while the adds San Ankou.
The also yield riichi/tanyao while the also add San Ankou. The loses tanyao, obviously.
Since the 1st situation has 3 tiles (4dots) that yield San Ankou and the 2nd situation has 6 tiles (6bams, 9bams) that yield San Ankou, I would think that would be the way to go.
BUT WHAT IF ALL TILES ARE NOT AVAILABLE.
Suppose the 3 tile San Ankou had 12 tiles available for the win while the 6 tile San Ankou had only 8 tiles available for the win. What then?
I assume the answer will be that it depends on how badly you need the points.
With a nice lead, go for the 12 tile available win.
If playing serious catch-up, go for the 6 out of 8 San Ankou win.
But what if the game is close and you are right in the thick of It?
And what if you are sitting EAST for a possible dealer mangan.
How much risk is getting that San Ankou worth for those extra points?
Any and all comments are welcome.
