That would certainly be a good thing to check before using Go's shuffle for real-money poker games. I wouldn't take it for granted.
> Also, I'm keen to see what shuffle algorithms you know of that aren't susceptible to RNG issues
There are not and cannot be any such algorithms. That's the entire point of this thread. Fisher-Yates is necessary but not sufficient. You either have sufficient random bits for your shuffle or not.
