The following game has a surprise move in a less-than-usual line, and when I researched it in earlier posts, I found a number of editorial errors. Strange...
bemillsy - leoarthur
blitz, FICS, 2012
1.e4 e5 2.Nf3 Nc6 3.Bc4 Nf6 4.O-O Bc5
See "Jerome Gambit vs Two Knights Defense (Part 4)".
5.Bxf7+
A delayed Jerome Gambit move order (or a transition to a "modern" Jerome Gambit line, 1.e4 e5 2.Nf3 Nc6 3.Bc3 Bc5 4.Bxf7+ Kxf7 5.0-0 Nf6), although there are about 550 examples in The Database. I have never played the line, but of course Bill Wall has, as have GeniusPawn, GmCooper, HauntedKnight, hinders, sTpny, Teterow, DragonTail and jrhumphrey, to name just a few.
The line was looked at in the games aymmd - MOMLASAM, blitz, FICS, 2010 (0-1, 19) and Wall, B - Guest848078, PlayChess.com, 2012 (1-0, 10) although there were diagram errors and references that subsequently needed correction in both posts.
5...Kxf7 6.Nxe5+ Nxe5 7.d4 Nf3+
A surprise, but not as strong as the routine 7...Bxd4.
8.Qxf3
The correct capture, with a roughly equal game.
8...Bxd4 9.Bg5
Overlooking something, perhaps already short of time.
9...Bxb2
Surprisingly, not Black's strongest move, although it does lead to some advantage. Rybka prefers 9...d6 10.Nd2 h6 11.Be3 Bxe3 12.Qxe3 Re8 13.f3 Qe7 14.Rad1 Be6 15.b3 Kg8 with a clear advantage.
10.Nd2
White should try 10.Qb3+, as after 10...Kg6 11.Qxb2 Kxg5 12.e5 he has chances against Black's uneasy King.
10...Bxa1 11.Rxa1 d6 White forfeited on time.
