The only striking thing I notice here is that villian is 30/10/6, which seems quite loose passive to me. This leads me to believe that he's likely only raising top of his range. The shove really is probably the “best” play, but I may be more inclined to flat and play post flop in position here. If we whiff flop, we are still going to have 18BB.

While I think shoving is probably default, just wanted to give you another line to consider. If this player is more in the 30/18/6 range, he would likely have hands such as KJ/KT/K9S, QJs/QTs/Q9s in his range as hands we are absolutely crushing. If he's going for a much more polarized stealing range, he will possibly have hands like K2-K4s and Q2-Q4s as well. We don't want to be shoving here and folding those hands out. He's going to call off with all hands that beat us, but fold the ones we crush that can flop top pair and pay us off at least 1 bet.
