Game information

You can see the diagram for each move by following along at this HexWorld link.


The following is an annotated transcript of a Hex game. Follow along with this on a board, and you could learn all kinds of stuff. The players are H and V, V moves first. H is a bit weak in the opening, but the mid game is wide open after a questionable move by V. V ends up preserving the win by carefully maintaining the winning line throughout some tricky positions.

1. f6   The center hex, the strongest opening move for V.
  ... f5 H chooses a weaker line of defense, g3 is usual.

2. h4   V presses the attack on the north edge.
  ... i1 H plays the "classic" defensive move. Note that g5 may look tempting here, but H is in trouble after h5.
3. e4   V shifts focus to the right side, threatening, but not establishing, a link to the north.
  ... e3 H's piece at i1 allows this defense, but f1 might have been better.
4. g2 g3 H can stop V's connection to e4 or h4, but not both!
5. i3   V is now connected from the north. j2 or h2 both get the link, and H can't stop both.
  ... e9 H shifts sides and tries to play defense on the south.
6. h7   Nice, aggressive, offensive and defensive move.
  ... g10 H's game is all defense at this point.
abcdefghijk12345678910112434532656
7. i9   V connects to the south, choosing to fight for the link in the middle rather than along the edge.
  ... j2 H's first sign of life on offense. H threatens h2 or i2, which links H from the right out to f5...
8. h2   But, V shuts the door on that!
  ... h6 This piece is linked to the right, even though it's not the usual 4th row template, thanks to the H piece at h2,
9. j5 i4 V tries to block, and H saves the link.
10. g7?   Not a terrible move, but d9 was probably better. V links up in the center with this move.
  ... g6! If V responds with a knee-jerk f7 to save the link, H looks pretty good after g5.
abcdefghijk12345678910118799108107
11. d6!   A nice reply to H's strong move. V de-fuses f5, and extends from e4, which could end up being connected to the north.
  ... g5 H makes the link anyway. Perhaps H would have been better off moving on the south side here.
12. f3   V keeps the sure thing to the north.
  .. f7 H is now connected from the right out to f7/e9.
13. c9   Once again, V gets a link and plans to fight for connection in the middle.
  ... d5! A very sneaky threat. If V plays a knee-jerk e5, H plays d9, and forces V to choose which side of c9 to play defense on. If north, H attacks south at b11, with some north ladder help at d5, and east ladder help at g10. If south, c8 wins for H.
14. c6!   But V sees right through all that! This move strengthens ties to c9, and allows V to stop H even if H makes the e5 link.
  ... g1 H tries to throw some doubt in V's ability to stop H from connecting from d4 to the left.
15. f2 f1 V forces two ladder steps, which restores ability to stop
16. e2 e1 H after H's threat of e5.
17. h1   Now this is safe for V.
  ... c8 H's last gasp at a win. Inexact play by V could lead to a ladder east then north to H's link to the east edge.
18. e7   The only win-preserving move in the area.
  ... d8 Forced.
19. e8 Resign Threatens to connect at d9 or f8; H has run out of tricks. H resigns.
