Reykjavík Open 2013 (7.6), 24.02.2013

Position 1
The position is complicated. White has a mobile mass of kingside/central pawns while black's is not yet castled. What do you suggest for white?

• 22.f5(cash in right away while black in uncastled)
• 22.Rhf1(complete mobilization first as black is not safe castling on either wing)
• Something else

White to Play

21...Nd7

Position 2
