How do I spend time on chess in boring meetings? I will be sitting in two boring meetings and each one is several hours long. I do not need to participate in any way, nor is the information from the meeting useful to me. However, my presence is expected and I am not supposed to look at my books, phone, notebook, etc; but a quick glance at a piece of paper may be tolerable. Chess is my hobby and I am seeking advice on spending time mentally on chess during such meetings. By the way, right now I am unable to play blindfold chess.
Any ideas on how can I enjoy chess in my mind in such situations?
One posibility is to concentrate in problems.
Write on paper the posicion description, using a notation like the following:
This fen: 
r1bqk2r/pppp2pp/2n1pn2/5p2/2PP4/5NP1/PP1NPPBP/R2QK2R b KQkq - 0 7 

Corresponds to: 
W-Ke1,Qd1,Ra1,Rh1,Bg2,Nd2,Nf3,Pa2,b2,c4,d4,e2,f2,g3,h2
B-Ke8,Qd8,Ra8,Rh8,Bc8,Nc6,Nf6,Pa7,b7,c7,d7,e6,f5,g7,h7
Black to move.

Annotate your answer as a continuous line of moves without the move numbers to simulate note taking.
