1: i dont hate it but i think theres more value betting 40 something than overbet shoving. and bigger on the flop too.

2: raise flop > check behind turn > the way you played it. theres no value in betting the river here either. hes calling almost all pairs and you beat all draws.

3: fold pre. i think raising the river is good but i think he pays you off for $15 with any A and probably any J so raise bigger. Like GOAT said we're never getting b/3 bluffed on this river.
