But those two words go to the heart of what it takes to be a good player. It's the way we can continually improve. Okay, so doing the right thing in each circumstance is not a groundbreaking idea. In poker decision-making, logic is the Holy Grail. The term or mental process called logic means different things depending on the context.
Logic is a branch of philosophy.
Logic is also a branch of mathematics. For instance, if you read an opponent for a bluff and call him, and the opponent was bluffing, but he overlooked his hand and actually has the nuts, this bad result is unimportant. Doing the logical thing is doing the sensible thing. Sometimes in poker un-sensible things happen. We can't be concerned about that.
