Originally posted by LennyBruceBelieve me, I have studied the article in some detail. I got the link from my opponent the first time I was confronted with the Halloween Gambit (Game 1122427), of course after we had played to the point where the analysis ended (I am a bit proud that I found a line which is slightly better for black all on my own). I have played the Halloween as White several times after that with varying success. Did you read the second part, too? I think the main advantage of the Halloween is the surprise effect, but in Correspondence Chess, that won't help you much, at least not against players who use databases and take their time.
That's not what I got out of the article...perhaps you should read the link before making such a claim.
