The riichi call changes everything on a table. You cannot trust omote suji on a tile used to declare riichi.
As with everything in mahjong, the same theory can be applied with varying efficacy. Kabe suji is no different.
Suji is so en vogue nowadays that an oft neglected tool in the defender’s box is kabe.
Can you read a 7 pairs discard pool or no idea what to look for? I HATE reading for 7 pairs.
Suji… The first defence tool in a Riichi mahjong player’s tool box. Just relying on suji alone can be a bit of a blunt tool.
