Almost every chuuren attempt starts life as a full flush. The signal worth watching for is a triplet of 1s or 9s in your long suit early on, with the rest of the tiles spread across the middle. If both terminal triplets are within reach, reshaping the hand can be worth it. If not, take the chinitsu and be content — it is 6 han on its own, and breaking a live tenpai to chase nine gates is the classic way to turn a big hand into nothing.

The hand must stay closed, so a single chii or pon ends the attempt for good and leaves you with an ordinary flush. Plan around your own draws and nothing else. Watch furiten closely too: flush hands carry wide, tangled waits, and it is easy to have already discarded a tile that now completes your hand — check your own row before calling ron, and see how furiten works if that rule is new to you. Land the pure form, with all nine waits live on the final tile, and many rulesets score a double yakuman; WRC scores every yakuman as single.
