Swimming with ICCF sharks

With COVID-19 shutting things down, some players have switched to playing webserver-based correspondence chess. The International Correspondence Chess Federation (ICCF) has many big events and some can earn you norms towards titles.
But with databases and strong engines available, it's like swimming with sharks. You've been warned. In one game, as we reached the middlegame, my Indian opponent announced that I was losing a piece by force and he would chase down my extra pawns. I doubt he labored over the position in his chess lab. Most likely he just fed it to his chess engine.

The game presented here is my 16-move crush of a Slovak opponent who proudly announced that he doesn't use engines. Of course, this is great for his chess improvement but not for his ICCF rating. He should stick to online chess.
