I don't think he needs Rosengren until it's tournament time. His biggest use is tactics and analyzing opponents anyway
I can't believe you're serious
In fact, if Robin really started light training only in late December-early January, February is too early date for play in tournaments. When he will able to train fully, he needs ( that other players have done in the offseason) - hard training for 3-4 weeks for 5-7 hours every day.Only then we can talk about participation in tournaments.
hope he will be ready for spring Masters.
