This is a turn based game I recently played against Hebrit on GameKnot. Playing against Alechine's Defense is not in my repertoire, although it should be, as black plays Nf6 on move one. Luckily GameKnot allows and indeed has an integrated opening book, which makes it easier to survive unknown openings. Actually I often play thematic tournaments on GameKnot to develop my opening repertoire.
The game below has a nice trap and combination at the end, I think.
