Have you ever played King's Gambit Accepted Tumbleweed?

Yeah, I see what you are saying. His knight would have my Queen. I missed that.

I just saw your, and yours is definitely a lot better than me as you keep the knight at bay. Nice! Also, here are the other two I was talking about:

What's the point of both 8...d4 and 8...Bd6?

Probably blunders form his opponent. But when you play blitz sometimes you can make mistakes you know.

This is one of the oldest gambits and it can be very complicated for both sides and very risky. Why would White take that risk when he has a chance to start the game first? That's why it's not being played by grand masters. However, that doesn't mean that it is not playable. To be honest, I wouldn't play this gambit in an official tournament even though I got my first win in a USCF tournament with another variation of king's gambit accepted. The funny part is that this tumbleweed variation has 100% winning rate since there are only two games in chess.com's database and the games go back to early 1900s.

Here is a 3 minute blitz game that I just played (along with 2500 strength computer analysis);

Move 8 is a killer move in this game because Black could either lose his queen or get check mated with bishop and a rook. My opponent used most of his time on that move then he found the two bishop sacrifice. 

In total he got 8 blunders in the game and I got only one and that was because of timing. After move 37 we both had about 10 seconds on our clock. You can find the details in the analysis.

WOW that king move. Why do you do that? Can somebody help me with that!!!

Chill man

have I played this variation? no and I never hope to.
