It’s unsolved. The bread part is poker, and the meat part is chess. Yes, there is a ton of io, but the meat can pick the strategy.

Try this call no more than 3 times in 60ms, and get back to me. It’s complicated and frustrating and not always worth it, but even with lots of io, the logic, the strategy, can live in the pure compositional parts.

Your mileage may vary, but it’s often worth a little thought at least.
