Thoughts
Unexploited weaknesses. Adorjan's doubled F pawns seem like an obvious target but he pins black's knight with 13. Bg5, starts executing his own plans and they never become more than a theoretical problem.
Misplaced pieces. In order to maintain material equality Murkhin's pieces end up disconnected from the defense of his king. Adorjan converts a pawn structure weakness to bad piece placement.
Bad Bishop. Fixing black's pawns on c5 and e5 completely hems in the black dark squared bishop ends up acting as a glorified pawn while white's dark squared bishop maintains scope of action.
