@Frankdawg Come to think of it, after your posted analysis, it looks like not a very good idea to take with the rook, better for the rook to wait there and die. Meanwhile black can prepare some counterplay.
The rook will not die. After Nxd7 ...Rxd3 cxd3 ...Kxd7, the pawn on c5 is lost.
a) There's no pawn on c5, b) I was talking about black's response to Ne4.
I mean f5. b) response: okay
My analysis engine does not think Ne4 is a winning move. It is the only move that does not lose, but it leaves an equal position.
Black should respond 1.. Ke7, after which Nxd6 is not the best move for white, the rook can wait. Start with Qc3.
Well, the point is that it's a clever move (in that it acts both as defence and attack in quite a complex position). I'm impressed though that the analysis showed that Ke7 was the best response for black. It confirms the idea that I expressed in post 9 that moving the rook is probably not the best think black can do. Thanks for the analysis!
