Calling with Ahigh+gutter, he can be doing anything.. can think of FDs, 98,T8 type of hands to 7x, 54,77..

If I do range cbet OTF, I have to defend some Ax hands OTR as well. From what I know, this line is not perceived either highly overbluffed/underbluffed. So its probably best to stay with MDF. Okay, since we should call some Ax, however, we dont need to defend all of them. I like to call those without a heart (blocking his possible FDs) and those which contain an 8,9 or T, since I see most of his bluffs coming from that region. Having 4 or 5 should be the best blocking 54,43,53,74,75 and even 64,65 and unblocking most of his bluffs. Even AK,AQ,AJ are good ones bc I doubt that random Jx,Qx,Kx would take this line somewhat often enough.
That said calling with A4,A5 and AJ+ sounds best to me.
Maybe vs this guy, calling every Ax is profitable..?!
