After thinking about this I kind of think this guy made a brilliant call… What hands do you have on each street here that make sense with the previous action?

On the flop: If we have 9x or TT you wouldn’t we be re-raising (if we do have a 9 the kicker is probably at least an 8, but I suppose 89 could check behind)? JJ+ probably 3-bet from the button PF? 22-77 all seem reasonable to just call?

On the turn: Unless we decided to just call with a 9 or TT, had 66, or picked up a draw, the turn is a blank. I think the most likely hand to bet here when checked to is a hand like 55, 77, a floated A or a flush draw. However, what suited hands float a flop bet here? AK probably doesn’t flat on the button very often PF…maybe AQs too, so if we remove those than I guess suited cards that connect with the 9 might (backdoor straight and lush draws on the flop)? TJ, JQ, KQ, TQ, KT? V is blocking the 78 combo draw, which probably doesn’t float the flop much anyway).

On the river: What hands in your range make it to the river and also make sense to shove with? At this point any 9, 6 or J have showdown value that is too thin to bet right? Perhaps a boat would just shove with the SPR so low. …V could have decided, “if he floated air and caught a back-door miracle, gg… boats are hard to make… call”.

I kind of wish you didn’t post the results because that might have forced my mind down this thought process.
