yes the defend is bad but we have huge pf edge.
and only calling turn to bluff most rivers

btn is super aggro and can even be bet folding hands like overpairs here though he almost certainly just had a complete airball. it's possible that btn is capable of bet folding an 8 here mostly bc we have a very tight image.

talk to me about ranges here please. i'm still on a big learning curve
