In the main line white will try to attack the black pawn from the opposite direction by bringing its rook to h7. To conquer the h-file, white has to bring its rook to h6 on the shortest way. That is the reason for the surprising sacrifice on e6!}) (6. Rf2 $2 Rh7 7. Kf5 Ke1 8. Ra2 Rh3 $1 9. Kg4 (9. Ra7 Rf3+ 10. Kg4 Rf2 $1 $11) 9... Rh7 10. Kf5 Rh3 {positional draw}) (6.
