I mostly play micro stakes ring games. There is not much room for bluffing
at that level since most people seem to be perfectly willing to raise and reraise with ridiculous hands over and over. Good for them if it works but I try not to raise too much unless I can put a lot of pressure on them. This means I tend to throw away a lot of cards.
However, I do not want to give my opponents the impression that I only play premium hands. I will gladly fold twice in a row, but by the 3rd or 4th hand I will make a strong effort to at least see the flop, even if I was dealt some junk like 3 7 offsuit.
