Move #33... Ngxf2
Brilliant move that gave the necessary advantage to win a very important game against the strongest opponent and allowed to move forward to the next round.
At first, I considered to take the f2 pawn with the knight in e4 but it would open the e column weakening my king protection. Instead, taking the f2 pawn with the g4 knight allowed me to check my opponent´s king forcing him to protect the king. At this point he had 3 choices:
1-move his king allowing me to take his queen with my unprotected queen and keeping a knight of advantage;
2-take my knight in f2 with his knight in h3 allowing me to take his queen with my unprotected queen, then take my queen, then I would take his knight in f2 with my knight in e4 checking his king and keeping a knight of advantage;
3-take my knight in f2 with his queen allowing me to take his queen with my knight in e4 checking his king and forcing him to move the king or take my knight with his knight in h3; either way it would give me a strong advantage against an opponent without a queen.
