Ok :)
Epic queen fork

Mehh, I just played one where my knight landed in a protected square.

Let's forget about opponent ratings though...
There are epic forks and then, there is . . . With my opponents King, Queen and Rook all positioned to be simultaneously forked, all I needed was for my opponent to move their second Rook away from protecting the forking square. They did, and moved their second Rook to . . . can anyone guess? . . . yes, to a square allowing a 4-way fork of King, Queen and both their Rooks.
To be fair, I should mention that it was a 15 min OTB game in a "for-fun" adult tournament at our high school state championships.

4. Bd3?! is dubious.
Because that's totally not mainline at all...
Yes, engines say Nf3 is better in this scenario, but the difference is minute.
i'd like to think i woudn't bite on that but after the knight sac my spider senses might have been tingling.
Ok, yeah really haven't studied chess at all... all I ever learned from a chess book was that controlling the centre is crucial to success. I could really use some literature... particularly anything that would help me with my endgame.. which is pretty weak at this point.
In this game, I make a sacrifice for a sweet queen fork. You can clearly see that my opponent does not see it coming. Check it out!
