At the 1980 French Open, Evert faced the 1978 French Open Champion Virginia Ruzici in the finals.
Evert and Ruzici had many exchanges that lasted about 20 to 30 shots, which went back-and-forth between deuce and advantage for over an hour, but most of those exchanges Evert won just by looking at the scoring line 6 games to love in the first set and two games to love to start the second set.
After a weird line call, Evert lost her serve for the first-time in the match in the third game of the second set, which she would go onto drop the next subsequent two games in order to fall behind 2 games to 3.
Evert would not let this get to her, and would win the next four games to with her fourth French crown, which Evert is noted to have said "at the start of this year.
I didn't know what my future would be...but this win has give me my confidence back in time for Wimbledon.
"Evert would make the finals at the 1980 Wimbledon Championships, which she would play Goolagong again for the title.
This time Goolagong had a plan to play more aggressively, which this allowed her to win the first seven points against Evert, and Evert lost her first two service games in the match to be in the hole love games to three.
In the fourth game, Evert would get her only game of the set that came off a break of service from Goolagong, but this set would be over in a half hour with an Evert loss of 6 games to her one.
The second set was delayed by rain partly the way through, but when they returned to the court it would be a more of the same.
Evert had a hard-time maintain her serve by hitting a drop shot from the baseline in the fourth game of the set.
At 4 games to three, Evert was up a break in the set, but Goolagong would break her serve to level the set at 4 games-all.
In the next game, Evert would be unable to convert on three breakpoint opportunities, which would prove costly later on.
Evert would eventually find herself in a must win tiebreaker, but would lose 4 to 7 points in the breaker.
The 1980 US Open final saw Evert face Czechoslovakian Hana Mandlíková, which Evert stormed out to a 4 games to 2 advantage in the first set only to lose five out of the next six games.
Evert was broken in the last game of the set at love to lose it 5 games to 7.
The second set started off via a break of serve for Evert to lead 1 game to love, which she would never relent from that point forward.
Evert would win the next two sets in a thrashing fashion only losing one game each in both sets.
So, Evert went onto win her fifth US Open title in six years having only lost in the previous year to Austin in the finals during this timespan. 
The developer must decide if the vPOIs must be completed in a certain order, or if the order is inconsequential.
Additionally, the developer can choose if the win condition of an adventure requires all vPOIs to be captured, or only a certain percentage of them.
Game creators can set a “Catch Limit” for each vPOI, which restricts the number of times each node may be captured.
This can be used to encourage races and competitive play.

An each-way bet is a wager offered by bookmakers consisting of two separate bets: a win bet and a place bet.
For the win part of the bet to give a return, the selection must win, or finish first, in the event.
For the place part of the bet to give a return, the selection must either win or finish in one of the predetermined 'places' for the event, such as in first "place" or second "place".
The odds paid on the place part of the bet are usually a fraction (commonly , , or ) of the win odds.
The trade-off being that one has a greater chance of making one's bet in trade for getting less payoff for doing so.
Examples are domestic football knockout competitions (e.g., FA Cup) where the quoted place terms may be .
In horse racing in the United Kingdom, the "place" is set strictly by the Jockey Club and will depend on the size of the field (that is, how many horses are running) so that the "place" may be just 1st and 2nd, 1st 2nd and 3rd, or even 1st 2nd 3rd or 4th on a big race like the Grand National, and may pay or the odds.
Mathematically, it is is better to make two separate bets on different outcomes than take an each-way bet.
