I haven’t played in two months and tomorrow I want to go play OTB, because I feel lonely. However my play is completely wrecked, stones feel so foreign (probably because I played chess and my brain reorganized its inner workings). For example, second and 18th lines look completely different even though it’s the same thing. What’s the best way to get my board understanding back? Blitz or classic? Smaller boards? Weak or strong players? Puzzles? Videos?
Probably the best way is to go and play OTB, as you plan to anyway, and just enjoy yourself for a bit. Your relaxed joy will fire up your brain and you’ll be back into it in no time.
Worrying about lost skills gains nothing - you just lose more in terms of the moment.
