Hello, Galfond has mentioned country reads a couple times in his videos mentioning Germans are tighter. I think Ansky may have talked about it a bit in some zoom videos on another site (seems to be most applicable to zoom because of lack of reads on a lot of players).  Also my friend had great success calling down spanish people wider in 180 sngs. 

Anyway I wondered If anyone had some other thoughts on this topic, or could give me any information on plays from certain countries? Thanks!
