Charleston strategy
The rules of the pass are short. The skill is which three tiles leave. For the order itself, read how the Charleston works. This page is the choice inside that order.
Name a section first
Look at the rack and say which section of your card it leans toward. Pass tiles that fight that lean. Keep tiles the section still uses. If you pass the core of the section and keep the leftovers, the hand you wanted is gone before East draws.
Do not draw a picture
Three tiles of one suit, sent together, tell the table you are done with that suit. A mix is quieter. The courtesy pass can be zero tiles. Passing nothing is allowed, and it is the right call when an exchange would name the hand.
Pairs and jokers stay put
A pair is hard to rebuild, and a joker cannot fill one. Break a pair when the hand has moved on, not on the first pass because the rack looks crowded. Jokers are never passed, in any Charleston pass or in the courtesy pass.
The second round is a choice
Anyone may stop after the first Charleston. If the table continues, the second round is finished once it starts: left, across, right. A blind pass belongs only on the last pass of a round, not on an across pass.
None of this reprints a card hand. The lines you are aiming at are on the card from the National Mah Jongg League.
