How to put intense attack pressure on a king (Took the ending part from one of my games.)

I took this position from one of my games. This is legit, even though the top says sample player vs sample player. To prove it or if you don't believe me, here's the link.

EXPLANATION:

After White played Nxc3, This looks like it brings defense to the attacked king, but in reality, it allows a forced checkmate starting with Qxg3. H-pawn cannot take because it is pinned. White noticing this, White plays Qe2 to desperately bring defense to the attacked king but it is over after Rg8, ignoring the threat on the knight! White seeing the attack and checkmate is nearby, White took d5 and another brilliant move, Qg1+, sacrificing the Queen! After Rook takes queen, checkmate!

If Rxf6 after Rg8:

If White plays Rxf6, Black will respond with Rh2+ and after Qxh2, The Black queen takes the rook on f3 and the Queen is forced to go to g2 and Queen takes Queen is checkmate

If Qxf6 after Rg8:

If this happens, You should play Rxh2+ and Rxh2 is forced. Black must respond with Qxf3+ and after the Rook moves, Queen takes rook is checkmate

If Rg2 after Rg8:

Black should respond with another brilliant move, which is Rxh2+After Rxh2, You should play Qg1+, sacrificing the Queen! The Rook is forced to take the Queen on g1 and Rxg1# is played!
