So basically I was taught to just play as if your ignoring the limper and raise whatever range you were going to play anyway. Is this still the most +EV play today? Are limps still just super weak hands like small pairs and suited connectors we can keep raising at a high frequeny? Or do we limp behind with some strong hands for balance and polarize our iso range? If people are not limp folding, do we isolate with a merged range?
