River line check

Villain hasn't been been at the table for more than an orbit.

Does anyone do anything other than b/f on the river vs an unknown? Is the bet sizing on the river and earlier streets fine?

you need 22% equity to make calling this river bet EV+....put him on a range, put him on a range, put him on a range.

As for bet sizing, on the flop i think id go for half pot because the 77-qq part of his range may be able to fold to a PSB but could probably still keep going vs a weaker cbet. (right guis?), as played when he calls that big of a bet on the flop your turn sizing is fine...river is probably good too. I am pretty perplexed as to what to do here, does he really play sets like this? thats about all we lose to aside from 45s, 67s and A3, i guess 88 is possible. idk i guess against an unknown with no reads id give him credit and fold

Yea you can bet a little smaller on earlier streets, and b/f river. It sucks because he's repping like 88/76s but meh, this isn't a spot to bluff.

Bet the flop a bit harder, other than that, standard
