[Event "How Does a Horse Move In Chess?: Knight Capture, Example"] [Site "https://lichess.org/study/kfwBxeWY/3TwqlOrj"] [Result "*"] [UTCDate "2023.05.31"] [UTCTime "17:37:13"] [Variant "Standard"] [ECO "?"] [Opening "?"] [Annotator "https://lichess.org/@/Juggernaunt"] [FEN "8/2k2p2/4p3/1b6/3N2P1/5P2/2r5/6K1 w - - 0 1"] [SetUp "1"] [Source "https://lichess.org/study/kfwBxeWY/3TwqlOrj"] [Orientation "white"] { Let's analyze in the following position the 8 squares controlled by the knight located on d4. The red arrow indicates that the knight cannot move to f3 since there is a white pawn on that square and, in chess, 2 pieces cannot occupy the same square and it is not allowed to capture your own pieces. The yellow arrows show 2 options that the knight has in this position, but one of them is not a good move. If we wanted to capture the e6-pawn with the knight, this move, from a general point of view, is legal and possible. However, it is not a good option since the f7-pawn would capture the knight on the next turn. And let's remember that the knight is worth three times more than a pawn. Now if we focus our attention on capturing the bishop on b5, which is not protected, we will also realize that the knight not only captures the bishop but also puts the black king in check. This all looks excellent, however, in the resulting position, Black would still be materially ahead. The blue arrows represent other options that the knight has, but those don't represent the best options in this position. If we move the knight to c6 or to f5, or even to e2, we can see that Black would capture it with the king, pawn or rook, respectively. Only on b3, the knight would not be captured; but this move is not the best option. White's best option is to capture the rook on c2, and this move is indicated by the green arrow. Here White captures the defenseless piece of higher value and achieves material equality. } { [%cal Gd4c2,Rd4f3,Yd4b5,Yd4e6,Bd4b3,Bd4e2,Bd4f5,Bd4c6] } *
