1k hands on villain, he's a reg.
20/16, 3bet 6%, folding to cbets 42%. FWIW, he's cbetting 63% but only double barreling 13%, which I guess we can generalize to mean he often only stabs once with bluffs (and probably misses a lot of thin value too). I just put that assumption together though while reviewing the hand tbh...

Does anyone have a strong opinion about potential other lines, or does this seem decent?
