Perhaps there is something I am not seeing here...
The opening puzzle position seems straightforwards, blacks bishop is hanging on E7, so I take it. Blacks response is to steel the pawn on g2, attacking both rook and knight.
I sat and thought about it for a while, castling queenside gives up the knight, I thought the solution must be King to e2 as it seems the only way to protect both pieces, but it says that castling is the correct move.
