+                A bet is whatever goes in on the first trip to the stack, unless the
+                amount was said out loud first. Reaching back for more chips without
+                having said "raise" is a string bet, and only the first motion stands.
+                Saying the number is always enough on its own: "raise to sixty" binds
+                whatever order the chips arrive in.

+                decide how much to bet. Say it, or push it all at once.
