An unexpected kings gambit variation lead to an 8-move checkmate.

Ya I knw dis trap bt on King's side seen 4d first time

It's basically Legall's Mate with a couple of extra moves thrown in, isn't it?

lol very nice =D go calum dude thingy.

rainbow rising, your sequence didn't come up, could you try re-posting please?

I think best for black is

6...dxNe5 then if

7QxBg4 Nxc2+ etc.

I believe Legalls mate only works if black has developed neither knight.  A generality perhaps, but like most generalities, generally true.

Why does it keep doing that?!?!

I see...

So, Nd4 wasn't necessarily an auto loss move, black just had to be careful :)

Thoughts?

Rainbow,

I sympathize with your board posting problems, and have had my own frustrations.

Instead of 8...Nxa1, in your blue line, 8...Ne3+ screams.  Even 8...Nf6 (rather than 7...Nf6) picks up a tempo and development and then the rook (really just the exchange).

I think my main point holds. That Legall's mate only works if black's knights are undeveloped.  Lots of variations though, and it remains a good pattern to know.  I have only used it once OTB, in 52 years of play.

Quite right Pawn, Ne3+ does scream!

Do you see that OP? By Nd4 you thought black was lost, I played a little further and thought black was ok, but it turns out there are plenty of pitfalls for white!

I played this otb this week.   The pattern here is one that everyone should memorise.  I managed to play this game in a 20 +30 game and I had 23 minutes on my clock at the end because I had seen this pattern before.

I felt sorry for the guy, pretty embarrassing to be caught by such a well known trap.

I was wondering why not Ne3+ for a sec.. then scrolled down...
