Matagi suji is a specific suji read that examines tiles near numbered tiles. It can be referred as "straddle suji". For numbers 3-7, they point to numbered tiles -2 or +2 away from them. For 2 and 8, they point to tiles 1-4 and 6-9 respectively.

Usage
The concept behind matagi suji considers a discarded tile as an interior tile to a waiting sequence in the hand. The idea may not be applicable to early discards, particularly first row. Players may not be tenpai at that point. Regarding tile efficiency, tiles discarded later may indicate potential tenpai shapes. They were kept long enough until no longer needed because of favorable draws.
