Rook+Knight Endgame-Play For Checkmate? I found myself in this position as Black during a recent endgame situation with White to move.
[FEN &quot;8/7k/2R4p/2p3p1/2N2p2/P4PnP/1P2r1K1/8 w - - 4 43&quot;]

What is a good way to approach checkmate from here? Is it impossible to force this with the rook and knight alone (with this position)? Or is it a better idea to start pawn play along the e to h files?
Some general advice about kings cut off on the 7th(or2nd) rank in rook endgames.
Involve your king or get your N to f3.
1.Kg1 Nf5!? {going after the f3 pawn.} 2.Rxc5 Nd4 (2...Kg6 also comes into consideration but
 is not tricky enough. although it is my personal fave) 3.Kf1! (3.Ne5?? Rxe5! -+) Rh2=

Involve a pawn!
1.Kg1 h5! {in order to get a pawn to h3 or f3 ASAP. Black will then threaten mate in two ways: ...Rg2# and ...h2#} 2.Rxc5 g4! -+

I have only used my head to give instructions. No computer, just to show what the general plans are. I'm IM but compared to a comp I'm nothing. So please forgive me if this is completely wrong. The general ideas are still valid though!
