I am playing white. The game analysis said my next two moves are blunders (moves 21 and 22 for white), even though it is forking the king and a rook for a knight. I'm new to chess but I cannot understand why this isn't a good move for white considering I am trading a knight for a rook. The analysis gave me 2 blunders for this move, the first blunder when I forked the king and rook, and the second blunder when I captured the rook with my knight.
Here is the game:
lichess.org/EVirKZHy/white#40you have to consider stopping the black pawn from promotion which would happen easily if u had traded your knight and easy win for black after promotion
I think the computer thinks that you could have gotten a lot more (better position and maybe even mate) if you had used the queen and knight in tandem to attack the king. The evaluation drops to -0.2 (slight advantage to black) when you capture the rook, and I think that this is a combination of your attack running out of steam and the passed pawn of your opponent.
Maybe somebody higher rated than me can correct if I'm wrong.. :)
@ErikFranNorrland , do you are wrong as per me ( any higher rated correct me if i am wrong ) , you need the knight and queen to defend yourself . look at blacks c pawn ..it is 4 steps away from promotion . if one had given away knight , his opponents king is now more safer and can easily promote his pawn which cannot be stopped
@WillBeAGrandMaster Yes, but if white would have captured the pawn on e6 with the queen rather than trading away the knight, black is getting mated unless he sacrifices the queen for the knight..
I agree that giving the knight for the rook in this case is bad due to black being able to promote the pawn to a queen...
I would also capture the Rook and then play Rook C1 to Block the Pawn, is this an Option?
@GoPackGo17 eventually black will play Nd3 to support the pawn push and drive away the rook at c1. That's why white shouldn't trade his knight away for the rook; it protects d3.
What does the comp suggest instead?
This is just my guess but, I think it's because after the knight check it's harder for white to continue on an attack, it's still possible with some knight and queen maneuvering, but after you take the rook black's king is surprisingly safe and white has no more firepower to continue an attack, now the focus is shifted onto black's past pawn on c3 forcing white to retreat with the queen and deal with the pawn threat, during that black can add some pressure to the position.
I guess after black won the rook , if black did not hang M1, it was an easy win for black
