CHAPTER 14

The full table.

The hardest mahjong situations aren't one-on-one. They're when two or three players are simultaneously dangerous, the wall is running down, and every discard feeds someone. This chapter is about managing that complexity.

01Threat hierarchy

Not all threats are equal. Rank them by urgency.

Stage 1Three exposures

Wall · Turns

Immediate. One tile away from winning. Highest priority to defend against — any discard is a candidate to deal in.

Stage 2Two exposures, flushing

Wall · Turns

Building toward a specific shape. Moderately urgent — track what suit they're keeping and stop throwing into it.

Stage 3One exposure, visible pattern

Wall · Turns

Developing. Watch and track. Not yet dangerous enough to fold against, but worth adjusting discards.

When two players reach the highest threat level simultaneously, you're in the hardest defensive position in mahjong. The only clean options: hold a tile that's safe against both (rare), discard toward the less dangerous one, or have won already.

02Two-threat discard strategy

01Find the overlap

Tiles in both players' rivers are safe against both. Honor tiles that both players have already discarded are the safest category.

02Throw toward known danger

If Player A needs characters and Player B needs bamboo, throw bamboo first — it's safe against A. Known danger is easier to navigate than unknown.

03Discard toward the lower payout

If you must deal into one of two dangerous hands, prefer dealing into the one with fewer exposures and a less-developed flush — pungs are capped; a deep flush player can hurt you much more.

04Accelerate toward a cheap win

In a two-threat situation, winning fast with 3 faan beats folding. A small win stops the round. This is the rare case where speed fully overrides score.

03Late-wall play

As the wall drops below 30 tiles, every decision shifts.

Close to tenpai (0–1 shanten)

Accelerate — accept a slightly weaker tenpai shape to arrive faster. A two-sided wait with 15 tiles left beats a perfect wait with 8. A last-tile win (海底撈月) adds +1 faan as a small bonus.

Far from tenpai (2+ shanten)

Seriously consider folding. Reaching tenpai with 10 tiles left doesn't give enough draws to win before the wall ends. Focus entirely on not paying.

Safe tile lists become your most valuable asset as the wall shrinks. Maintain the list mentally — every discard you see updates it.

04Drawn game decisions

When the wall is in the last 15 tiles and nobody has won, the probability of a draw is rising.

1In tenpai with a live wait: stay. Draws are neutral — no payment, no penalty.
2In tenpai with a dead wait: evaluate whether to break up and defend or hold for the slim chance.
32+ shanten: fold completely. You're not winning this round — protect against being the one who pays.
4Nobody is close: consider whether your discard list looks dangerous. Even in a likely draw, one careless throw can deal into the one player who somehow reached tenpai quietly.

05The discipline of adjusting

All of the above requires reading the table continuously, not just at decision points. Players who handle complex tables well track threats passively — every discard they see updates their mental model automatically.

This skill develops with experience. At first it feels like too much to track. After fifty sessions, you stop "tracking" and start just knowing.
