I have seen videos and range graphs of what to raise with preflop, however I am looking for a graph range of what to call with preflop once someone bet preflop from each position? So for instance if middle position bet 3x pre what do I call with OTB. I also understand it is a little of V dependent but feel there has to be a GTO calling range? So if someone could post a link to a video or a link to a thread I would greatly appreciate it.
