1. d4 d5
2. e4
 
This opening is Blackmar-Diemer Gambit.
 
2... dxe4
3. Kc3
 
    After this, Black generally plays 3... Nf6 for protecting e4 pawn. Then, White intends to follow this with 4. f3. And if black takes f-pawn (4... exf3), White has two options to take f-pawn: Qxf3 or Nxf3.
    White can play aggressive move instead of giving up two pawns for Black. 
 
    In this time, consider the situation of 5.Qxf3. By the way, this is Ryder Gambit.
 
First, Halosar trap derives from Ryder Gambit.
This trap comes into play after white queen side castling. The queen and the rook are same line by that castling.
Then, Black's bishop can hit both with 7... Bg4.
However, white moves 8.Nb5! If black took queen, White could get the mate.
It's so noticeable trap at first sight, but it might be valid one in the case of blitz and for careless players .
 
 
But if black notices this trap, what should we do? 
Let's take a look at some white's attacks in other situations.
 
Black can do this trap?
But I think it's hard to try this when White moves c4, Nf3, Bf4, e3 or Nc3 on his second move.
These moves is most popular in the case of queen's opening. 
So Halosar trap is not for Black maybe.
