Should I have a backup hand in American Mah Jongg?

It depends on how long you have been playing. If you are new, no: a backup hand splits your attention and you will play both halfway. Commit to your strongest hand and let the table tell you when to move. Once you are seasoned, yes, always. A seasoned player sits down knowing every option her tiles allow. If there is a clear path, she goes for it. If there is not, she keeps two or three hands alive until the tiles pick one.

The honest answer has two halves

Ask a table of experienced players whether they keep a backup hand and you will hear yes from every seat. Ask a teacher what she tells beginners and you will hear no. Both are right, because the question has a different answer depending on who is asking it. A backup hand is a tool, and like most tools at the table it helps the player who can use it and hurts the player who cannot yet.

If you are new: one hand, and mean it

When you are still learning the card, a second hand costs you on every single pick. Tiles that would be obvious discards get held because they serve the other hand, your discards slow down and give away more than they should, and you arrive at the middle of the wall committed to nothing in particular. Two hands played halfway lose to one hand played properly, and they nearly always do.

So while the game is new to you, pick your strongest option after the Charleston and put everything behind it. You will lose some hands you might have saved. You will also learn to read a hand cleanly, which is the skill the backup hand is built on later.

If you are seasoned: always know your options

A seasoned player never plays one hand blind. She sits down knowing what her tiles allow, and she keeps knowing it as the hand goes on. If she has a clear path, she goes for it and does not hedge. If she does not have a clear path, and most hands do not start with one, she keeps two or three options alive and lets the draws and the discards choose between them. That is not indecision. It is playing with the whole card in view instead of one line of it.

The difference between this and the beginner's muddle is that the seasoned player knows which tiles the options share and which they do not. She holds the shared tiles, lets the rest go without regret, and the moment one option pulls ahead she folds the others into it. Nothing is held just in case. Everything held has a job.

The two signals that decide it

Whichever kind of player you are, the table tells you when to move. A hand is weakened when the tiles you still need are going down in the discards, and wounded when they have been taken up into somebody's exposures. Both are things you can see. Look at what you still need, ask how many of each are already gone, and when the honest answer is none left, that option is over and the next one takes its place. Playing with options is what makes that move cheap instead of a fresh start.

If you are going to move, move early

There is a window for this. Changing direction is cheap while there are still plenty of tiles to draw and almost nothing has been exposed, and it gets more expensive with every pick after that. A workable marker is with about seventy of the ninety-nine wall tiles still to come: if the tiles are going to pick one of your options, that is roughly when they will do it.

Past that point the arithmetic turns. A late switch means starting a new hand with a shorter wall and a table that has already shown you what it is holding, and by then the honest question is usually not which option to move to but whether it is time to switch to playing defensively.
