First of all as someone already mentioned, this is not Nathans personal opinion but the result on a poll, he put out on his blog. So obviously it should not be taken to serious. And right off the bat to me it seems like, many people have understood the question as “which country produce the most annoying poker players” rather than “the worst poker players”.
Number 1 and 2 on the list is Russia and Ukraine. And if we are taking about people playing online micro and low stakes games, as the vast majority of Nathans audience is, then players from these two countries tend to be among the best on average. Many of them are playing in a semi-professional way for profit, they put in lots of volume, and they usually play either a TAG or a LAG style.
This can make them annoying, because they are difficult to beat, and because there are so many of them, they contribute to making micro and low stakes games tougher, than perhaps they ideally should be. If you buy into a 4,5$ SnG on Stars, it can be surpricingly reg infested. Which is perhaps not very good for the “poker ecosystem”, but it does not make all these grinders bad poker players.
As for richer countries like Canada, several of them have produced some of the best players in the world. But regardless of, which country they are from, the best players in the world dont play 5$ tournaments online. They play much higher stakes, because this is, where they can make some
real money.
So the Canadian players, you actually find in an online 5$ tournament, tend to be among the worst players at that limit. And the same can be said for any other rich country, where people have extra money to throw around on activities like online
gambling.
