No matter where that knight goes it's dying.<br/><br/>That said..<br/><br/>D4 -> B3 is bad because they can take it with their rook pawn and open the lane for the rook.<br/>D4 -> C2, E2, F3, or F5 we lose the knight and gain nothing.<br/>D4 -> E6 or C6 we lose the knight and capture the pawn.<br/><br/>Alternatively, we can move the bishop from F8 to B4 and they will take that piece instead because taking the knight would put them in check.<br/><br/>So those are the options I see as far as the knight goes. We could always ignore it and make another move as well. ^^<br/><br/>Will wait for input.
