A similar position including the "nudge", after 7.Qd5+ Kf8 8.Qxc5+ d6 9.Qc3 was seen in Wall,B - Boris, SparkChess.com, 2012 (1-0, 32), Wall,B -Guest4149739, PlayChess.com, 2013 (1-0, 30) and Wall,B - Guest428245, PlayChess.com, 2014 (1-0, 20).
The alternative, 8.Qd5+, looking for mischief, was seen in Wall,B-Guest4395, Microsoft Internet Gaming Zone, 2001 (1-0, 18); Wall,B - Seven11, Chess.com, 2008 (1-0, 51); Wall,B - Chung,J, Chess.com, 2010 (1-0, 25); Wall, Bill - CheckMe, www.Chess.com, 2010 (1-0, 23); and Wall, Bill - Guest249301, playchess.com, 2013 (1-0, 30).

Houdini rates Black about a half point better here; while Stockfish sees Black as maybe nine-tenths of a pawn better. That's plenty for White to work with.
Bill and I have exchanged emails about this move. I like it - a lot. It reminds me both of the comment attributed to Bobby Fischer - "I don't believe in psychology, I believe in strong moves" - and one by Nimzovich - that a particular move was strong, because it appeared weak...
Notice how Black jumps all over the move. Notice how Black loses.
13...Qb6+ 14.Kh1 Ng4 15.Bb2 Re7
As Bill points out, Black pauses for some defense: not 15...Nf2+? 16.Rxf2 Qxf2?? 17.Qxg7#
Likewise, avoiding 16.Qc4+? Be6 17.Qd4 Ne3.
Here we go again: attacking the White b-pawn.
Which White abandons!
Black has the pawn in the bag, and forks two of White's pieces. What's not to like?
Bill was aware of 18.f5? Qxb2 19.Qxg4 Qxd4 20.Qxg6 Qxd2.
We will come back to this position.
This looks like the beginning of panic. Black's Knights are at risk.

Going back to the diagram after White's 19th move let's ask: What would have happened if Black had admitted that his "advantage" had evaporated, that his "right to attack" had therefore disappeared, and he had retreated with 19...Nf6?
As I had emailed Bill
Funny how 19...Nf6, admitting Black's mistake, would have mostly set things to rights.. : 20.Qxg6 Qxb4 21.e5 Nd5 22.Nb3 a4 23.f5! Bxf5 24.Rxf5 axb3 25.c3! Nxc3 26.exd6 Re2 27.d7! Nd5 28.Raf1 Re1! 29.axb3 Ne3 30.Bc3! Qxc3 31.Rf7 Rxf1+ 32.Rxf1 Nxf1 (what else?) 33.Qe8+ Rxe8 34.dxe8/Q+ Kh7 35.Qe4+ and it was a draw, after all... But even in this line White has almost all of the fun!
