this guy is 21/18 with ATS of 30% in 6m but my read on him is that he's willing to 4b light
3b pre is marginal, but I'm not really really bluffing, in my mind it was for value, but it was really marginal I debated between 3bing and flatting for a second and decided to 3b for value

being 140BB deep I thought it's better to flat the 4b, ship the flop, and hope to fold out ace high and have 25% equity vs. any pair

how's my line?
