RxN removes the protector of the h pawn and allows bishop to check on the next move with discovered attack on the white Queen. White can avoid loss of the queen by giving up on the captured knight.

1. ... Rxf3
2. (a) gxf3 Bxh2+
3. Kxh2 Qxd4
At the cost of R & B, black wins Q, N, P

2. (b) Qe4 Rxc3
Saves the Q, but white has just lost two Ns

Rxf3 , so that if gxf3 , Bh2 check wins the Q.

2. gxf3 Bxh2 wins White's queen

Took about 15 seconds to spot this one. The main feature of the position is that the black queen is x-raying the white queen so black can play Bxh2+ to unveil an attack on the white queen. However the queen is protected by the knight on f3 so we simply take advantage of the "remove the defender" tactic with
1...Rxf3 simply winning a piece because if
2.gxf3 Bxh2+
3.Kxh2 Qxd4
and again we see the pitfalls of having a hanging piece as white can not pick up the knight on e7 without losing his unprotected knight on c3 so black would have a queen for a rook.

10 seconds:

1. Rxf3!

This knight was actually protecting the queen from Bxh2+ and Qxd4.

White is down with a piece since he can't take back but must instead find new protection for his queen.

1......Rxf3!.

If A-2.gxf3.Bxh2+.3.Kxh2.Qxd4. winning Queen for a rook.If.4.Rxe7.Qh4+or Qd6+ picks up wayward rook to be up Q for a N.

If. B-2.Rxe7.Bxh2+ transposes into A variation.

Black has to bite the bullet and save his queen by giving up his knight without compensation. if he is not careful, he will lose the N at c3 too!
If.C-2.Qd1/d2..Rf5! a N up and with an attack still on.
If.D-2.Qe/g/h4..Rxf3! winning another N!.

Again FEN notation is a waste.
1...... Rxf3 the object is more to remove support for white Q rather than weaken K position.
2.gxf3 Bxh2+
3.Kxh2 Qxd4 Because of hanging N at c3 black gets only one piece i.e. R for his Q.

1...Rxf3 and black looks to be up a piece or up an exchange because it removes the guard of the white queen, making a discovered attack with check possible if white re-captures.

For instance,
2.gxf3 Bxh2+
3.Kxh2 Qxd4 and black is up the exchange with a queen for a rook. Also, white's castle seems to be in bad shape with the h-pawn gone and the g-pawn doubling the pawns on the f-file. So, my guess is that black might not have a difficult time launching an attack seeing as he still has a queen.
