BillM416:
In my opinion, we need to do everything possible to instruct players to abide by some simple rules: If you are under the gun pre-flop, you may muck, call or raise. You may either announce that you are calling or toss in that exact amount. If you wish to raise, you must announce that you are raising...this will freeze the action until the amount is determined, or you must push the total amount forward in a single motion.
Without a verbal announcement of your intended wager before pushing chips forward; The single oversize chip rule will apply. Furthermore, a bet does not constitute a raise, they are two different actions. After the flop, each player will respond (in turn) by folding, calling or raising.
Bill, to answer your question: "What would it mean if a player tosses in two over-sized chips and says, either call, fold, or check?" First of all, I don't know how a player could do that and expect anyone to understand his intent. "Is his verbal declaration binding?" Yes, but only if his verbal precedes his action. "Would the chips put in the pot stay in the pot?" This would depend on a number of possible scenarios...
