While this is well in line with a recent game of mine (see "Here's My Plan...") as well as all of the "Jedi Mind Tricks" that I have been observing in the Blackburne Shilling Jerome Gambit (1.e4 e5 2.Nf3 Nc6 3.Bc4 Nd4 4.Bxf7+), where Black also declines the Bishop, it can hardly be called more than a psychological ploy.
It is as if Black declined being given "Jerome Gambit odds" and offered, instead, odds of "pawn and two moves" himself!
Watchwords for White in such cases must be: The price of victory is eternal vigilance...
blackburne - Talwhu
Chess.com, 11.2010
1.e4 e5 2.Nf3 Nc6 3.Bc4 Bc5 4.Bxf7+
4...Kf8
A hint from the updated New Year's Database: If Black is going to decline the Bishop, this is probably how he should do it. In 161 games, White scored only 54% as opposed to when Black played 4...Ke7, when, out of 26 games, White scored 71%.
5.Bb3 Nf6
Instead, perrypawnpusher - ibeje, blitz, FICS, 2010 continued in exciting fashion with 5...h6 6.Nxe5 Nxe5 7.d4 Qh4 although I blundered in the endgame and lost (0-1, 46).
6.Nc3 d6 7.d3 Bg4
blackburne had an earlier battle with some similar themes: 7...Bd4 8.Bg5 Bxc3+ 9.bxc3 h6 10.Be3 Bg4 11.0-0 Qe7 12.h3 Bh5 13.Kh2 a5 14.a4 Nd7 15.Qd2 Bxf3 16.gxf3 Nf6 17.Rg1 Rd8 18.Rg2 g5 19.Rag1 d5 20.Bxg5 hxg5 21.Rxg5 Rd7 22.Rg7 Qd6 23.R7g6 Ne7 24.Rg7 Rh7 25.Rxh7 Nxh7 26.exd5 Nxd5 27.Bxd5 Qxd5 28.Qh6+ Ke8 29.Rg7 Rxg7 30.Qxg7 Nf8 31.Qxc7 Ng6 32.Qc8+ Kf7 33.Qc7+ Kf6 34.Qb6+ Kf5 35.Qe3 Nh4 36.Qe4+ Qxe4 37.fxe4+ Ke6 38.Kg3 Ng6 39.c4 b6 40.c3 Nf4 41.d4 Nd3 42.h4 exd4 43.cxd4 Nb4 44.Kf4 Na6 45.d5+ Kd6 46.h5 Nc7 47.h6 Black resigned, blackburne - BrainFreeze, Chessworld.net, 2008.
8.Bg5 Nd4
This move should fail due to the tactical shot 9.Nxd4, as 9...Bxd1 is well answered by 10.Ne6+ Ke7 11.Nxd8 Bxc2 12.Nxb7 Bxb3 13.Nxc5 Bf7 14.Na6 when White remains a piece up.
9.0-0
9...Nxf3+ 10.gxf3 Bh3 11.Re1
This move seems okay to me, but Rybka was uncomfortable enough with it to suggest instead an exchange sacrifice: 11.f4 Bxf1 12.Qxf1 even giving White an edge after 12...Qd7 13.f5 c6 14.Be6 Qe8.
11...h6 12.Bxf6
It seems risky to invite the enemy Queen to join the party.
Rybka suggests 12.Be3 Bxe3 13.fxe3. Blackburne may have been wary of a further 13...Nxe4, as 14.fxe4? (or 14.dxe4?) loses quickly to 14...Qg5+. Still, 14.Nxe4 would provide a defense, e.g. 14...d5 15.Ng3 h5 16.f4, covering the critical g5 square.
12...Qxf6
13.Re3
Again, jettisoning the exchange with 13.Kh1 Bxf2 14.Rf1 Bxf1 15.Nd5!? was probably the best way to get some counterplay, even thought Black would have an edge in the resulting position.
13...Qg5+ White resigned
