On the ferry over to Helsingör recently, I was thinking about the Dragadorf, when another similar idea appeared to me.
1.e4 c5 2.Nf3 d6 3.d4 cxd4 4.Nxd4 Nf6 5.Nc3 h6!? About a decade ago I looked at something I called "the Anteater Sicilian" at the time (5...Nbd7) on my site. But iirc, white could keep an edge with 6.Bg5 - which would be one of the pros of the Dragadorf, as against 5...g6 6.Bg5 is nothing special.
Still, white's Qd2+Bh6 and/or ...b5 a4! resources made me wonder if there was something else with a similar idea. Thus 5...h6 eliminating Bg5 while black keeps it open what kind of d6-Sicilian he's intending to play.
Depending on white's 6th, black can go for 6...a6, 6...e5, 6...Nc6, 6...e6, 6...g6 and perhaps also 6...Nbd7.
I guess the choice depends on which mainline systems black knows best.
And since Bg5 is the mainline in several of those, I guess 5...h6 may not be completely useless to get white out of book in a delayed Classical, Najdorf, Scheveningen, Dragadorf etc
I've added a pgn-file with some games I found with the diagram position. To my surprise it has actually already been tried by a handful quite strong players.
