1. Flop is dealt SB first to act bets, UTG thinks its his go and calls OOT. Action goes immediately back to the BB who just calls the SB's bet...
However can if the BB was to bet or raise.
If, after the flop, the small blind bets, the big blind does not have the option to "bet," as you said. After the flop, after a player bets, the next player can call, raise, or fold. I am not answering your hypothetical. I am merely clarifying the possible actions.
I recommend, before you ask any questions, that you look through all of the rules, and see which ones apply to your situation. Asking questions and getting answers will not be a solution for you. Because, in the future, there will be a situation that you may not have heard of. Then what? In the future, if you ask real world questions, I recommend that you post your answers that have come from your research and thought process. If you are handed the answers, you probably will not learn.
If you hand a man a fish, you feed him for a day. But, if you teach a man how to fish, you'll feed him for a lifetime.
Andy, you need real world practice. Your understanding of the game is limited. I am not trying to be critical of you or insult you. But, sometimes, your questions remind me of a three-year-old asking his father how a car works.
Well, you turn the key, that starts the engine, you step on the gas, and you go.
But what makes the engine work?
Gasoline.
But what makes the wheels turn?
The steering wheel.
But how does it do it?
And on, and on, and on.
