villain was playing 29/23/18 in 90 hands. No history, no notes. Do we have a thin value OTR? Do we have any other bet sizes as an exploitline 20bb? After his confusing line, I think we are against something like A5s (1), A3s (2), AK (8), Axs(??), other crazy sh*t(??). I just cannot imagine, there are any straights in his range after this line. What do you think? Will we get enough calls from worse Axs to make river jam +ev?
