seems unlikely someone would snap overbet bluff the river at that juncture of the ME. then again, it was so long ago, can't remember how long it took Gia to check river. if longish, coulda decided then.
Not a fan of it at all. Gianetti had the top of his range (actually the next best possible hand) and still almost folded. Bet 2.5 and get paid off by way wider of a range.
I honestly don't think there's any difference in Gianetti's mind on the river between A9, K9, AK, AQ, etc. Lamb was pretty polarized there. I think he's definitely capable of overbet bombing a river with air
That said, it's obviously still really close. I'll just be results oriented and say fold :-P.
