In analysis, it says moving knight from f7 to d6 is the best move as it puts king in check but I am unable to understand how

Look at your light squared bishop.  The knight was blocking the light squared bishop's diagonal of attack.  This is called a "discovered attack".  Its often a great move, because the other side needs to deal with the check, and the piece that moved is therefore able to survive being in a spot where it would normally be taken.  Here, the discovered attack will allow the knight to take the rook next turn, a favorable trade.

Notice that the bishop is delivering check and not the knight itself. This is called a discovered check and is a pretty sweet tactic when you use it right. In this case, black cannot deal with saving the rook and stopping check at the same time.


Or just, you know, notice that I fully answered the question over a day ago.
