Do not call. Raise or fold.
That is one of the biggest mistakes of a beginner "It does not cost me much ". Tehy call with c.r.a.p cose they are donks. If U have premium cards raise like hell if there are a lot of limpers. Limping at freerolls
or microstakes out of position means they have nothing If do not have than fold. Do not be curious when there are 3-4 limpers because your chances of winning the hand are small even if u call with aces. Raise to make them fold or fold and wait another hand . Do not call beacause it is a big chance that one of them hits the flop and u lose your chips.
