Battle Between Brothers

Noah was playing white in this semi final contest. He has just taken Mackenzies pawn with his Knight. Mackenzie saw this as an opportunity to remove a dangerous attacker and allow him to develop into an even handed endgame. Was this the correct move for black? 

Answer: This is a blunder. This is not an even trade. When Noah's pawn took Mackenzie's Knight it exposed Mackenzie's King to a discovered check. This resulted in Mackenzie losing his rook as well, effectively ending the game.
