Deep Fork

This position, offered in Secrets of the Russian Chess Masters: Beyond the Basics  by Lev Alburt and Larry Parr, demonstrates a most unlikely fork that gives White a winning game from what seems to be essentially an inferior position.

That’s a sick fork.

Analysis says it’s better to promote to queen tho. It’s like +6 for knight promote and +13 for queen promote.

Are you sure? It is pretty obvious that a knight fork is better, since it just simplifies. The computer probably saw an attacking line with the rook, queen, and knight.

Great tactic. I want to underpromote some day to win the game.

I just clicked the self analysis button. I’m pretty sure it’s what it said. I thought it seemed weird tho.

Yes I checked again it actually said +14 for queen promote. Not sure why lol.

I’ve seen this one in other books, or at least one other book. Maybe Alburt’s Chess Training Pocket Book.

Maybe he's Alburt the Repurposer?

I think letting the Black Queen on the board is more dangerous.  Being up the exchange and a distant pawn looks almost unstoppable.

Alburt’s exercise inspired this one that I created as part of my elementary set for young players, and then put into a self-published book.

Such tactics are simple and obvious once one becomes aware of them.  Tactical problems produce many "ah-ha" moments.
