if there is 0 in the side pot, sure check it down. But unless your on the bubble if there is a single chip in the side pot, and the only way you can win is to bluff, then bluff. Its not my fault if you are to scared to call my bet with the best hand. I am playing to win the tournament, which means I need to win all the chips, If I see chips that I can win by bluffing I'm going to bluff. There are very few situations where I would rather a person get knocked out than me winning some chips, there are some but not many.
