Ok, we’re good from the new position and off whites first move you just put up on the new board here. Now whites second move is the knight on a3 to c4 capturing the black bishop and putting black in check again. Nothing black has can recapture so the black king only has one move to back up one capturing the white knight on f5. Whites third and last move is the knight on d3 to fill the gap left on e3 from my first move. This leaves the black king in double check from this knight and the rook on c5. The black king doesn’t have a move to escape and can’t block both checks equaling checkmate in three moves for white like you asked everyone to find. The only thing I’ve been asking is if I missed a recapture or something in one of these three moves making this description above incorrect since I did it in my head and not a board like you’re using making it more clear.
