Although I’ve never played for any extent of time I understand a big strategy in poker is to call somebody’s bluff. This is a great strategy in many regards but it’s also dangerous. Case in point Olin Corporation (they manufacture Winchester labeled ammunition) is moving it’s manufacturing plant after a union vote to refuse a pay freeze.
Basically members of the union thought Olin was bluffing and called them on it. Here in lies the example of why bluffing is dangerous, your opponent may very well be telling the truth. Personally there are a few things I’ll gamble on, my job isn’t one of them.
