Lucky, again!

Refreshments served!
How long did you think about move six? What other moves did you consider? Any?
In a tournament game, I probably would have played this: 6. Qe2 Nf2 7. Qe3 Nxg2+.
What is a double pawn break? A diagram would be awesome if you’ve the time.
11. 0-0 was aesthetically pleasing.
That ending is just brutal! He should have sat on his hands.
Thanks for the post, ‘Prawn. Your annotated games are a fun read. You’re an intelligent and engaging writer.

Just a couple of minutes thinking, Nf3 looked to be safe (playing a new opening on no knowledge and didn't want to make a chump of myself). e5 looked attacking but ultimately over-ambitious IMO. I didn't consider any other sixth moves.... have you seen something?

I don't understand this, can you check your notation? Posting a diagram would be better.
What is a double pawn break?
What I mean by this is somewhat nebulous, just an idea, nothing concrete. What I'm saying is that, at some unspecified juncture, I might be able to play the c3 pawn to c4. Assuming my opponent plays c6, then cxd5 cxd5 c4 (again).... this would leave me with a d-pawn that has potential to go to d5, really stirring up trouble.
Obviously there would be other pieces on the board, just for illustration of the idea.

I meant 8. Qe2. I'm not sure why it seems to screw up the numbering when you cut and paste from the analysis board.

Qe2 Nf4?? Bxf4
But maybe I should have looked at Qe2 more seriously, just seemed like something I didn't need to get involved with. You know, the old King and Queen on the same half-open file and Black able to castle immediately.
p.s. Oh! you mean *YOU* in a tournament... damn! I'm slow sometimes!

I've had a look at a few databases and let Houdini take a look. The upshot is that my opening play wasn't too bad, given that I was on new ground and had to "discover" the moves for myself.
However, I missed a trick when I played 6. Nf3 and not 6. e5:

In your variation with 13.Bxf3 I think it gives an interesting position after 14.gxf4 (but not rook takes as you said).
By interesting I mean white has some pretty clear ideas (attack or c4 break) while black seems passive to me... well I guess he'd just take the bishop and then it's white who's a little worse so nevermind :p
Same set up as last year huh? It's almost too bad it ended so abruptly... good thing you didn't offer a draw :)
Last year, I played a match in the Kent League (average under 171 ECF/ approx 2015 FIDE), in which I felt I had a somewhat fortuitous result. Here's that game:

Well, one year on and the same match, same board (4 out of 6) and the same opponent. In the intervening time, I'd dropped a few points and he'd put on a few points.
Venue: Hastings and St. Leonards Chess Club
Time control: 36 moves in 90 minutes, followed by a 15 minute quick-play finish. This gives a three and a half hour game.
Playing conditions: Excellent: wooden boards and sets, digital clocks, refreshments served by the housekeeper.
So, I beat the same guy, two in a row, entirely on his blunders.
Feel free to comment, improve my play or celebrate my good luck (again!).
