Forward motion
Also: single forward motion
The principle that a single continuous movement of chips toward the pot is a binding action. One push forward is one bet; going back to the stack for more is a string bet and will be ruled down to the first motion.
Forward motion is the rule that makes a live betting action unambiguous without anyone having to read a player's mind. Chips committed in one uninterrupted movement count; a second trip to the stack does not, unless the amount was declared in words first.
The practical lesson is that words beat chips in a live room. A player who says "raise to four hundred" may then make as many movements as it takes to build the amount, because the declaration fixed the action before the chips moved. A player who says nothing and reaches twice has made a bet of whatever went in first.
The rule exists to stop a specific angle: pushing out a small amount, watching the opponent's reaction, and adding more if they flinch.

What is forward motion in poker?
The rule that chips committed in one continuous movement toward the pot constitute the bet. Returning to your stack for more is a string bet, and the action will usually stand at the amount in the first motion.
How do I raise without breaking the rule?
Declare the amount in words first. A verbal declaration fixes the action, after which you can take as many movements as you need to assemble the chips.
