I raised nearly every btn and cbettet every flop till now so my tableimage was kinda aggresiv and villians seems to start steaming a bit (atleast this was my feeling)

he cr my a few times before (not often) but he alraise raised only 3x my ammount not 4.5x times...

if i call here i pretty much commit myself unless i play c/f turn

what is your plan here? do you just muck it?
