1. e4 e5 2. Nf3 d6

[This is Philidor's Defence, named after François-André Danican Philidor, the leading chess master of the second half of the 18th century and a pioneer of modern chess strategy. He was also a noted opera composer. It is a solid opening, but slightly passive, and it ignores the important d4-square. Most modern players prefer 2...Nc6, and 2...Nf6 (the Petrov Defence) is also popular at master level.]

3. d4 Bg4?!

[Though 3...Bg4 is considered an inferior move today, this was accepted theory at the time.[3] Today 3...exd4 or 3...Nf6 are usual. 3...f5 (Philidor's original idea) is a risky alternative.]

4. dxe5 Bxf3

[If 4...dxe5, then 5.Qxd8+ Kxd8 6.Nxe5 and White wins a pawn and Black has lost the ability to castle. Black, however, did have the option of 4...Nd7 5.exd6 Bxd6, when he's down a pawn but has some compensation in the form of better development.]

5. Qxf3

[Steinitz's recommendation 5.gxf3 dxe5 6.Qxd8+ Kxd8 7.f4 is also good, but Morphy prefers to keep the queens on. After Black recaptures the pawn on e5, White has a significant lead in development.]

5...dxe5 6. Bc4 Nf6

[This seemingly sound developing move runs into a surprising refutation. After White's next move, both f7 and b7 will be under attack. Better would have been to directly protect the f7-pawn with the queen, making White's next move less potent.]

7. Qb3 Qe7

[Black's only good move. White was threatening mate in two moves, for example 7...Nc6 8.Bxf7+ Ke7 9.Qe6#. 7...Qd7 loses the rook to 8.Qxb7 followed by 9.Qxa8 (since 8...Qc6? would lose the queen to 9.Bb5). Notice that Qe7 saves the rook with this combination: 8.Qxb7 Qb4+ forcing a queen exchange.

[Although this move prevents immediate disaster, Black is forced to block the f8-bishop, impeding development and kingside castling.]

8. Nc3

[Morphy could have won a pawn by 8.Qxb7 Qb4+ 9.Qxb4 Bxb4+. White can also win material with 8.Bxf7+ Qxf7 9.Qxb7, but Black has dangerous counterplay after 9...Bc5! and 10.Qxa8 0-0 or 10.Qc8+ Ke7 11.Qxh8 Bxf2+! In keeping with his style, Morphy prefers rapid development and initiative over material.]

8... c6

[The best move, allowing black to defend his pawn without further weakening the light-squares, which have been weakened by black trading off his light-square bishop.]

9. Bg5 b5?

[Black attempts to drive away the bishop and gain some time, but this move allows Morphy a strong sacrifice to keep the initiative. This move loses but it is difficult to find anything better; for example 9...Na6 10.Bxf6 gxf6 11.Bxa6 bxa6 12.Qa4 Qb7 and Black's position is in shambles.]

10. Nxb5!

[Morphy chooses not to retreat the bishop, which would allow Black to gain time for development.]

10... cxb5

[Black could have played 10...Qb4+ forcing the exchange of queens (11.Qxb4 Bxb4+ 12.Nc3), although White would retain a technically won game being a pawn up.

11. Bxb5+

[Not 11.Bd5? Qb4+, unpinning the knight and allowing the rook to evade capture.]

11... Nbd7 12. 0-0-0 Rd8

[The combination of the pins on the knights and the open file for White's rook will lead to Black's defeat.]

13. Rxd7 Rxd7

[Removing another defender.]

14. Rd1

[Compare the activity of the white pieces with the idleness of the black pieces. At this point, Black's d7-rook cannot be saved, since it is pinned to the king and attacked by the rook, and though the knight defends it, the knight is pinned to the queen.]

There's some reporting on Dubya's reaction to Trump's inauguration speech. He is supposed to have said, "That was some weird shit." But one has to keep in mind that there is no love between the Bushes and Trump, not since Trump savaged Jeb in his bid for the presidency.
