The move seem to be very strong. >>I wonder why it has not been played more. I checked this out also. In my book, made up of over 660,000 games, 11. d4 is not present. Two comments: 1. As white I'm not sure I would toss that pawn. There is compensation, but computers are much better at grabbing a sacrificed pawn and holding on to it for dear life than they are at offering a pawn and then pressing the advantage they accrue from doing so. 2. If d4 was in my book, in "tournament mode" I would not play it because crafty does a shallow (1/10th normal search time) search to make sure it isn't about to play a "lemon" that slipped into the book. In this case, the eval for 11. d5 is -.55 thru 14 plies, so it would conclude "bummer" and resort to a normal search not playing the book line. I'd suspect if it has been played 3 times and all were wins (Tim's were very short wins with what appeared to be blunders by black in both) then some GM's have looked at it and decided it was not sound, and are simply waiting for someone to try it on them to reveal what they found. :)
