Not sure where the fatal error was. Maybe

looks good for black. One line is
So I suppose black J6 wins the left side, in large part due to the D14 peg.
is best. White threatens J5 which constrains black's response. White also threatens O6. There is nothing black can do.

Crafty, there, Twixter; That L9 move, threatening J5 or O6 appears to win the game for white! You are playing a move that sets up future threats, which are not at all apparent - at least to moi. K8, loses, L9 wins ...
Actually, pretty cool. I like that. I hope to be able to think that way. Maybe someday.

Well it was shyryan's idea in post mortem. You could call the L9 link a shallow glide (gliding "down" to the top border,) as opposed to K8 which is a steep glide. All that room for white on the right of J6 is what makes L9 work. For example |
stops both J5 and O6 but then
works for white.

- how about

, for example, but then after
it looks pretty similar to just going straight for

So I am trying to generalize:
with the rest of the game being irrelevant, after
then it would appear that White has already achieved reaching the top border, and Black can do nothing to prevent this!? White has Peyrol's threats of J5 and O6, and so far, Black's attempts with
have been busted. Is there nothing that Black can do? Maybe
If not, it just seems to me that the Twixt board has been shrunk - like you can be guaranteed to reach the border with a peg in the square formed by

Without the other pegs on the board, I'm not really sure what you are asking. Yes L9 wins the top if you ignore the bottom. So white can win a 13 row handicap game in this way.
The opening moves are crucial. There are three or maybe four moves you make in a good game, usually in the opening, which involve more intuition than calculation, and the rest of the game you try to tactically justify the plan that you are now stuck with. More and more these days, opening intuition is being replaced with specific opening knowledge. This is why I like 30x30, not necessarily more than standard, I just like it.
Oh and thank you for the compliment earlier. I often don't take compliments well.

I noted that L9 was shyryan's original idea, and failed to give him credit; credit given where credit is due!
My 'compliment' to you was to the follow up moves you cited, which explain the underlying threats made by L9; these are moves that I would normally have not spotted, and I found them to be 'crafty', and thus my comment.
To further explain what I meant in my last post about 'shrinking the board', perhaps some polygons:
One used to think that it was necessary to have a peg on, or past this polygon in order to be guaranteed of reaching the nearest edge.
However, the discussion above with
seems to imply that a peg on or past THIS polygon (with L9 on it) will do the trick:
The second polygon is SMALLER, which is what I meant. I am trying to see if I can generalize a rule here as to how far from the edge one can be in order to GUARANTEE reaching it, past any defense. Of course, in this specific game,
, blacks specific defender of J6 may be the problem here - maybe if black had chosen a different move, then the J10 - L9 link would NOT be guaranteed to reach the top.
What do you think? Have I at least made my concept and question clear? (meow)

David, are you aware of a repository of opening knowledge that is coming to replace opening intuition? All I've really seen is charts that show whether most players swap on certain opening moves.

Mr. Cat: The issue of whether J10 is unstoppably connected to the top or not sounds like you are talking about a template, which is a term used in Hex. Certainly templates can be useful in Twixt, but IMO it's not as easy as it is in Hex to draw a conclusion about the full board position from template knowledge. So if you agree with me about that, then I guess we are in agreement.
shyryan: I'm just referring to the growing archive of games which are available to study both on this site and with Jtwixt.
