Can somebody explain me why Knight f7 (check) is a wrong move? At least chess.com thinks so....

Thank you in advance

Cause rook h7 is mate

Can somebody explain what is wrong with knight f8?

Thank you in advance

There is a better move, Rxh7+ leads to mate in 4

You just need to get better

What is wrong with knight g3?

Thank you in advance

can someone please help me what is the best move for white to make

there's a mate in two, bishop d1, then qf2#. ng3 just loses a piece.

Nobody has pointed out yet that there is a button to the Analysis page (a small magnifying glass icon), where the engine answers every question.

In the last position, Ng3+ just loses. White plays Kg1, and now the white king is safe, while the black king is getting checkmated soon.

I started with bishop h6 check and after black did bishop g7 my move was pawn f6

Why chess.com thinks it is wrong? If black takes my bishop I take rook

Thank you in advance for answer

As I mentioned above, the Analysis tool is the small magnifying glass icon.

In this case, 1. Bh6+ Bg7 2. f6(??) Bxh6 3. fxe7 Kxe7 and the position is equal.

Are all puzzles taken from real games?

I am asking because of this https://www.chess.com/puzzles/problem/2427128

I have a question about second move of that puzzle

What is the difference if I take bishop at c6 with my queen (chess.com said it is wrong) and if I take it with rook (chess.com said it is correct)?

Thank you in advance

1. ....Qxc6 2.f3 Qxf3 3.b5 which makes the game . pretty much even. If 3. ....Qg2+ 4.Qxg2 Bxg2 5.Kxg2 not good at all.

1. ...Rxc6 Now the pawn cannot advance because the Queen is blocking from moving! To avoid mate, white must play 2.Qd6 Qxd6 winning a Queen.

A really neat thing for you to keep in mind, is to use analysis when you are unable to figure something out. With that you can see what the engine says, but also make other moves that you think may work, and find out why they do not.

I was thinking Rook e3 and if opponent takes with bishop knight c3 check and fork

Am I understand correctly that to trade rook and knight for queen and two pawns... is simply too...generous?

I am asking because sometimes puzzles like all sort of crazy trades

Thank you in advance for the answer

You are right. Black is much better in that variation. The puzzle is wrong, so it should be reported... except I don't think there is an option to report bad puzzles anymore.

I don't understand... why they call move 3 for black briliant?

It is easy to see... if not to do it black will be in trouble

Thank you for the answer

P.S And first two moves for black are also too easy for a puzzle (take the queen with knight and it will be fork)

Chess.com calls a move "brilliant" if it's a sacrifice and it's good.

"Easy to see" has nothing to do with it. Every tactics is easy to see for an engine.

I don't know if something has been changed since this was posted.

It is a mate in one puzzle. 1. ..... Nf4# While Rxe3 is winning, mate trumps.
