The 4 is a really good card for me because it blocks a bunch of his value combos. I still think he could be showing up with TT, 44, A4, AT, T4s, maybe AT which is still quite a bunch of combos. OTOH it's quite hard for him to show up with many bluffs unless he's randomly clicking buttons (which honestly is possible, too). I'm a bit scared of him already overbetting the turn. If it went lead, 1/2p lead, slight overbet river, I'd snap this off without even thinking twice about it but in my eyes, the turn overbet significantly strengthens his range. Can we therefore think about folding this? Where? River or even OTT already? If not, does that mean, we should at least be calling any Ace here because we have the same amount of blockers to his value range and he's not vbetting worse than AT?
