First of all, I don't know for sure how to share images of the board here, but I've shared the PGN info here from the Lichess board analysis. That said, there are only 9 pieces on the board so I can use notation to set the field in text. For White, Kf1, Rd1, Nf2, and a pawn on a3. For Black, Kd2, Rf8, and pawns on g5, d6, and a6. Black in check and to move.
I'm playing Black and White previous move was Rd1+. I thought I could take the Rook with my King because White's Knight is pinned by my Rook on f8. I was playing on the DGT Centaur board and it wouldn't let me make the move. Thinking it was glitched or salty about blundering a Rook, I went here to see what Lichess's analysis tool would say. And it too isn't let me take the Rook. It suggested Kc2.
What fundamental rule of chess am I missing here? To me, White's Knight is pinned by my Rook. I understand that by taking the Rook, my own Rook becomes pinned until my King leaves d1 or White's King leaves f1.
I'm just perplexed that two separate chess engines are saying that I can't take the Rook and I can't understand why. I'm hesitant to post this, because it feels like I'm missing something obvious, but I'm genuinely stumped. Any help explaining would be greatly appreciated.
