Chess Traps #6: Blackmar-Diemer Gambit (Halosar Trap)

This video looks at a possible trapping line played by white in the Blackmar-Diemer Gambit known as the Halosar Trap. The trap is very dynamic, and with solid play from black can still lead to a passed pawn for white and a very strong position if black avoids losing substantial material or the game by making mistakes.

Very nice. Love the traps in this one. Thanks for posting
They didnt cover with the knight the covered with a pawn
I never thought of this before. Thanx jrobi, I widh I could of played this when I was inn elementary school.
Not so fast here… Clearly white’s D1 Rook is pivotal for the entire trap to be effective. If / when black’s Bishop takes D1, white is left in a lurch. Your thoughts?
@jrobichess at what minutee is thaat?
Black hurts its position even more by taking the rook, losing a lot of material. It’s another subtle trapping line that will lose black the game. For example: 11. bxd1 12. Qc6+ Nd7 13. Qxa8+ Nb8 14. Qxb8 and so forth. Thanks for checking out the vid!
Wow that does look fun.. hehe I wanna try this!
Wow I just noticed at 4:07 the game is completely over for black. By moving that bishop there, checking the king, black is forced to block it with the knight or rook, most probably the knight, then you simply catch the knight, check, the king moved to d8, you move the bishop to a4 (discovered check), then they have to block with the rook by moving it to d6, and then, DAMMIT NEVERMIND, but it still is an even better continuation after that.
what software do you use? the arrows and all tht stuff is part of a software or you have to draw each thing for your videos?
i like the idea of answering e4 d5 with this trap
This trap could be good at blitz
What if black captures the rook on move 10 instead of capturing the dark bishop with the queen.
instead of 10. Qxa6 Qxe3+ …it’s 10.Qxa6 bxd1 11. ??
what happens if the black plays e5?
This may be my favourite youtube video to date, excellent job.
okay, now i don’t understand why black’s bishop can’t take the rook after white’s queen takes knight on a6.
Black loses a lot of material due to the resulting checks and captures unfortunately. Scroll down a bit for the actual line. Thanks for checking out the vid!
now that you are on the gambits, could you please make a video on the Hobb gambit against the bear opening ex. 1.f4 g5 2.fxg5 d5
I just used this in a blitz tournament last night. Slightly different move order but I won in 12 moves. thanks!

but i don’t understand why black’s bishop(g4) can’t take the rook(d1) after white’s queen takes knight on a6..
“3:21-3:33″
If black wanted to defend against the knight going to c7 checkmate, he could have just captured the rook with the bishop at g4. Black moved Queen to c5 to defend against the real threat, white Queen to c6 check!!! Great video. Keep up the good work.
very nice video on this trap, unfortunatly any trap that you or I as a player might play will always be beaten by the player who insists on using chess software assistance which I have noticed over the years of playing on line chess is getting worse for now they are using autoplay with such engines as the “chess buddy” which is a free download trial program to evade detection from the chess server.
chess websites are awash with cheating engine players.
@takataone Why do people do that? I mean the you might have an online rating of 2200 then but in reality you can’t play shit… isn’t kind of the whole point of playing online to practice so you can get better?
Trying this against someone, and unfortunately the black player moved his c7 pawn to c6 instead of taking the d4 pawn.
Now things are going back and forth so I gotta watch myself.
Instead of Na6, my opponents also play Qa5…what should i play to defend it?
