The 1st diagram is just the position for people to look at and evaluate the position (i.e. which side is better in both material (easy) and position). The actual puzzle will be the 2nd diagram. Study the position first then see if your analysis is the correct one.

Material should be easy and by no means am I saying that just because one side has a lead in material (by counting points) that it is the best and only way to figure things out; or that it's even necessary for everyone to do.

I know that some players here are so strong already that this is easy stuff for them. I apologize to anyone that might find this a waste of their time. I hope there's people out there that I can somehow help out in any way with this since that is my goal.

White seems to be threatening Nxd7 winning the Rook after playing Nfe5; The Knight on f7 is well protected by three other pieces --- the Rook(d7), Bishop(g6) and the Queen(b7).

Black decides to threaten a more valuable piece, White's Queen and the g2-pawn threatening mate. Black's other options are Rxd1, or Bxe1 if White plays Rxe1.

An aggressive reply by Black to White's attack, but is it the correct play?

Note: Black is actually up simply by a pawn.

In this diagram, solve the puzzle.

If Nde1 was a wrong move, what move should Black have played in response to White's Nfe5?

~

1.Nxg6 hxg6 2.Rh3+ Nh6 3.Rxh6

 Good! but ~ If Nde1 was a wrong move, what move should Black have played in response to White's Nfe5? What was the best continuation for black?
