Which famous movie is suggested by the following chess position (by Trevor Tao)?
This is also (one would hope) not the intended answer, but I'll go with the garbagious
That would be because to my eye white can only win by
after which there are a lot of transformers, as
white and black both promote three queens, which immediately get exchanged away at H1.[FEN "8/8/P7/P4N1p/P7/7p/P6p/n1K3k1 w - - 0 1"] 1. Ng3 h4 2. Nh1 Kxh1 3. a7 Kg1 4. a8=Q h1=Q 5. Qxh1+ Kxh1 6. a6 Kg1 7. a7 h2 8. a8=Q h1=Q 9. Qxh1+ Kxh1 10. a5 h3 11. a6 h2 12. a7 Kg1 13. a8=Q h1=Q 14. Qxh1+ Kxh1
The sequence seems forced: white wins this way, and any deviation from black leads to being down a queen.
After this, the white king will step to b2, confining the black's Last Knight into the corner, and the final pawn is free to march to a8.
If you have a better suggestion for a movie based on the solution to the chess part (and you probably do), please drop a comment.
I think this could be:
Black Hawk Down (2001)
The only difference between the two sides' available pieces is a single pawn - specifically, black has one fewer...
'Hock' is a synonym for 'pawn' (as in to deposit a possession with a pawnbroker) and in some (US) accents a soundalike for 'Hawk'...
Thus black is one pawn down, giving us:
'Black Pawn Down' → 'Black Hock Down' → 'Black Hawk Down'!
Both sides have one knight and one king. The plot of the movie centers around a cadre of young women in bondage (pawns) spending a night with a king (being promoted to queens) after which one queen remains. This assumes that white moves first and the game proceeds as @Bass outlines.
1. Ng3 h4 2. Nh1 And now there are three pawns on the horse.
I already posted this in a comment, but might as well make it an actual guess:
Henry VIII (2003) (or maybe Henry VIII (1979), or even Henry VIII: Man, Monarch, Monster - last one doesn't have a date associated with it, and it's a TV series not a movie, unsure if it was officially released or not. I'm surprised there aren't more of these, and none were theatrical releases. Maybe there's some other famous Henry VIII movie that just doesn't have his name in the title?)
Henry had 6 queens, most of whom didn't last for very long. In this sequence, we see 6 pawns promoted to queens and then pretty much immediately captured. (In reality, 2 of Henry's wives outlived him, but whatever - point is except for the first, none of them were queens for very long.)
These answers have been very entertaining for me, thanks everyone!
Here's my guess:
Seabiscuit was a horse who beat the 1937 Triple-Crown winner War Admiral, by 4 lengths in a 2-horse special in 1938. The White Knight on the board is Seabiscuit. The "Triple-Crown winner" is the Black King, who has 3 pawns who can promote to Queens. It takes "4 lengths" (4 moves) until White wins with a Checkmate: 1) Seabiscuit initiates with
a7is Checkmate. In this "2-horse special", Seabiscuit becomes our heroic champion!
It could be
The white king can pin the black knight and take it,
While the black king can force the white knight from its position by fear of pinning
The last part is a little sketchy. I haven't played chess in a while. I don't know many terms. :)
Because it looks like that's going to happen in the game, but it's not a definite outcome, and there are more pieces in play and many aren't required to support the idea.
Looks like time to put this thing to bed once and for all
The movie is Groundhog Day since this question was asked on 2nd February
And of course
The moves (already pointed out by several solvers) involve repeated promotions and captures on the h1 square, thus justifying the Groundhog Day theme :)
