opener is some nitty 16/14 over 90 hands (though most aware players will be playing pretty nitty with the fish and me to your left). dude to his left is 36/14 fish who has folded to 1/1 3bets but i expect he is terrible in 3b pots and calls way too much. he also has donked 5/7 flops.

my question is, is there merit in 3bet/folding under the assumption that EP nit ONLY 4bets like QQ+,AK and probably calls with a few worse hands like 88-TT,AQs, and that we get a ton of value whenever the fish calls?
