pretty simple AK hand

[Hince]

I think his range is largely rather weak holdings and you probably aren't getting too much value here most of the time. I doubt he bets many hands that are weaker than yours on the river, so you end up calling when you are behind on the river. Therefore, I think you should bet small ($60) as we can probably extract a little value from something weaker, and may induce a raise from something weaker that assumes you are weak and trying to get a cheap showdown. If you bet too much more, I think you let him play perfectly.
