Here we go, from some easier level to the absolute brilliancy. Whether you are new to chess or an expert, you will be entertained in this blog.
Game 1 - Killer Bishop?

Did you find the move? That was a great move and very hard to find! It is the only move that works! My opponent missed Be4 here and played Bxh7. I then proceeded to capture a seemingly free pawn on h2, attacking his bishop.

In this position, @WWWind19 sacrificed the bishop with Rxd5
This came from my game here , but it was a draw by repeition instead. I found this amazing when I analysed my game, when the brilliant move came out for my opponent. 

Well played.

Game 2 - Castling for your king to safety
When you learn chess, you are told to castle early as possible. What about a brilliant castling move? 

Game Link over here! Amazing game, and I got 3 brilliant moves (and 7 mistakes).

The end part was crazy too, as I flagged my opponent out. 
Through this bishop hanging is like a brilliant move generator. 
Game 3 - A sudden BOOOOOOOOM of explosions

En Passant checkmate!! (Almost because bishop block). Did you solve it? Let me know!
Game 4 - A quiet move of pieces

Another bonus puzzle from one of my games
