Post about MICRO games.
It is true that it is somewhat harder to bluff on the internet (and I'm talking about a stone cold bluff): people tend to chase and call even with 3 pair no kicker, even in PL or NL games. What does that teach us ? Unless we have very good position (last to act after the flop), you are facing few opponents (2-3 max), the flop is very dry and THE POT is also very dry, we shouldn't attempt stone cold bluffs unless we know the opposing players is /are capable of folding. Since we need to bluff in order to increase our deceptiveness, it is better to do so in small pots than in big ones, since the pots don't get magically big (someone is bound to have a big hand that doesn't warrant a fold). When we go up in stakes, bluffing in big pots is a move that should be attempted more often. In micros, it won't work often enough to be +EV against a good portion of the opponents we will face.
On the other hand, we should semi-bluff (drawing to the nut with more than 10-12 good outs) more regularly and also value-bet more, since people are more likely to pay us off. We should also learn to fold the big hands (AK, namely) when unimproved against opponents who are still following after a flop and turn bet (and even then, I'm starting to let go of AK regularly against more than 1 opponent on the turn UI in small to medium pots).
PS: I'm not talkign about c-betting when I say to bluff less often in first paragraph. C-betting should be a mainstay in your arsenal since against most opponents, even at the mircos, it will get you a fold 60-70% (maybe not on the flop, but probably on the turn).
