 {{main|Kabe}}
-Kabe is a tactic similar to suji. If all four copies of a tile are visible, then it is impossible to have a ryanmen wait on certain tiles nearby.
+Kabe is a tactic similar to suji. If all four copies of a tile are visible, then it is impossible to have most types of sequence wait on certain tiles nearby.
-For example, if you can see all four copies of 3-pin, then 1-pin and 2-pin cannot possibly be part of a ryanmen wait. This is because no opponent can possibly have a 23 or 34 shape, because no opponent can have a 3 in the first place. Tiles towards the middle, such as 4-pin or 5-pin in this case, are not much safer, similar to how half suji are not much safer.

-Like suji, other waits are still possible. Kabe is comparable to suji (though kabe is safer), and should be used in a similar fashion.
