Quick one

[Magikist]

The way the opponent is described, it sounds like it's impossible to move him off anything decent, even king high. We don't know exactly what Nate's image is at the time, and that's very important when discussing scenarios like this.

To me, calling the flop with the intention of semibluff raising the turn is a bad idea. Given the description of the opponent, there's little fold equity and J5 has absolutely no showdown value. As a result, you are forced to bet the river when you miss, and it's hands like these that burn chips.

A relentlessly aggressive opponent who autobets is very easy to exploit. Hit the board and raise for value. There are much better times to get involved than this one.
