Both of us have pretty healthy stacks and I know Apestyles can be a loose cannon at times but he hasn't done anything out of line yet. We haven't tussled much but I do think he thinks he can run over me. Also what is his 4xing range here? How am I supposed to approach this spot? I don't really like smooth calling but with both our stacks so deep, reraising doesn't seem great either. It just seems like a really sketchy spot.

What's your approach?
