    Share your cool checkmate. Just got this one. The game was a 10 min blitz

    Hopefully I can get another one of these lol.

    8 games on rhp have reached the same position through move 5. Not one person played Bd2. Nobody went for this checkmate.

    Well played. According to Crafty black gets a 1.7 pawn advantage after 8. ... Bxa2, after 8. ... Nc6 it's only 0.58, but either way if black avoids the temptation then you're behind. So 8. Ne4 only works as a trap (as opposed to a pitfall which doesn't cost you anything if black avoids it).

    On my database, which consists of the Crafty opening book with duplicates and (most) engine games removed and TWIC going back a decade or so and some other odds and ends and has 3.42 million games on it, the position after 7. 0-0-0 appeared once between two strong players, the game went on for a little longer though, 120 moves. This is Svetushkin, Dmitry (2,501) vs Tikhomirov, Sergei (2,326) 1-0; 2002 Supercom Cup, Bucharest:

    Those guys are a tad bit better than either me or my opponent. Thanks for the game. I was considering b2 to protect the pawn, I like the bishop better.

    Looked at the end of that game and he had the king in the right corner, but he did not know how to finish the knight bishop end game, but how many people do?

    I think Black actually resigned at that point.

    Black's opening in the original game in this thread reminded me of a sneaky trick which only two or three people have tried against me in many hundreds of online blitz games where I've played the Old Indian:

    So far I haven't fallen for it even when I'm tired.

    Edit: Thanks @Eladar, I managed to get it working by putting a line break every four moves rather than every five.

    I just got the exact same checkmate as black, this time offering the Scandinavian. My opponent turned it down.

    This version is better, my moves could be seen as natural responses with a knight blunder.

    How much time did you have to play that game? Your mating net is awesome, other options I checked were all inferior.

    2 minutes plus a one-second increment [one second added to the time after each move].

    @BigDoggProblem

    Helps explain his poisoned pawn. But still your ability to pull off that attack under that time constraint is impressive.

    Hi Guys,

    If we are showing blitz games then please forgive me for re-posing (sic);

    *** Thread 134311***

    "Next time you are going to play a blitz session, open up this thread
    and rub your finger against my avatar and some of the greenpawn
    luck I had in this game might just rub off onto you."

    If you cannot be bothered to go to the linked thread and the intro, here it is.

    M. Rattray vs. G. Chandler, Bells, Edinburgh. October 2006
    (published in 'The Scotsman' newspaper 23rd December 2006.)

    I finished this recently on this site. My opponent resigned just before checkmate so the last two moves are "what would have happened". The sacrifices didn't really work, but black gave material back when he didn't need to and then missed the problem with his queen, see note move 39.
