Couple hypothetical examples where I think RRoP vaguely or doesn't address:
1. Alex is facing an option to bet or check. Without a verbal declaration, he grabs 25 $5 chips, brings them over to the middle of the table, cuts out three chips, and brings the rest back to his stack. What is the bet?
According to RRoP, absent a verbal statement, "a wager is not binding until the chips are actually released into the pot." Released is a vague term. Alex's betting style is very common in 2021 and it's almost always ruled as a $15 bet. Back when RRoP was last updated, players were still arguing about betting lines and forward motion.
2. Bobby and Charlie are heads up on the river. Bobby bets $150 with six $25 chips. Charlie thinks for a while, then pushes out 10 $25s. Is this a raise or a call?
According to RRoP, "a player who has taken action based on a gross misunderstanding of the amount wagered may receive some protection by the decision-maker." Pretty vague, right? In TDA poker rules, this is a min-raise to $300.
