Is it really won for black? What is the right plan? Should black take on e5 or play Nd7 instead? Can I fully trust engines in such endgames?

Hi,

without engine analyzes.

Black pawns on king size are very strong. White pawn structur isn't really good, in this case the knight is stronger as the bishop in this endgame. Black king should go on queen site. In combination with the knight black have more possibilities as white. Black pawn on g7 should go to g6. For the moment Nd7 is OK.

Not easy this endgame but I think the better position have black. With other words remis or black will win this game.

Black pawn on d4 isn't important for this game, white can have it and lost time to bring the king in the middle of the board.

Best
Frank

It does not look like white will be able to do anything on the queen side. Black will just push forward on the king side and the 2 pawns should be able to win.

This is my own assessment of the positions, the computers might find some tricky way to hold a draw.

Watching it as human i think about Ne8 and Ng4. It seems to me that after Ne8 black has advantage, am i overlooking something?

Critter's score of 1.74 is from Black's viewpoint, since Black is on the move. So Critter's assessment is that Black has a strong advantage here.
