PNF: Sitting in a gold mine or just an annoyance ?
力量常规前锋：黄金还是垃圾
BY HT-TASOS – POSTED ON MARCH 3, 2018
It’s been almost a season with the new special events, and one of the most
discussed change is the new Powerful Normal Forward (PNF). How valuable is
he? Should I buy or train one for my team or will it be just a hole in the
water ?
新的特殊事件改版上线已经一个赛季，
讨论度最高的改变是新出的PNF(Powerful Normal Forward)。
PNF究竟多有价值 ? 应该买或是练，替自己球队配置一个 ? 还是其实不重要 ?
Let’s summarise the rules for the PNF again. You need a powerful forward
with high playmaking and scoring. For any such a player, the higher your odds
of creating such an event. In specific:
让我们再次检视PNF的设定：你需要一个高组织以及高入球的力量特技前锋，
有这样的球员，创造这个特殊事件的机率越高。
– With only one PNF, you have 10% chances of letting your players try to
score like that.
– With two PNFs, the probability increases to 16%
– And finally, with three PNFs, you have 20%.
具体而言
- 一个力量常规前锋，有10%机会出特技。
- 两个力量常规前锋，机率提升到16%。
- 三个力量常规前锋，机率有20%。
When does your team have that opportunity? Right after a missing, normal
chance, the probabilities above get into the game. If you are lucky, then the
playmaking skill of the chosen PNF is compared against the sum of the
defending skill of the central defenders. All side effects (form, stamina,
experience, health, loyalty, homegrown bonus) take their part in the
calculations. If your opponent doesn’t have any central defenders, then no
one is there to stop you reaching the goalkeeper.
什么时候会出这个特殊事件呢 ? 就在错失一个普通机会后，前述的机率会导入，
如果你很幸运触发了特殊事件，被选中PNF的组织技能会对抗对方中后卫的防守技能总和，
所有辅助效果(包括状态、体能、经验、健康、忠诚度、母会加成)都会纳入计算。
如果对手没有中后卫，那么就没有任何人可以阻止你长驱直入和守门员PK。
If you pass the defenders, and only then, it will be decided if your event is
a success or a failure. At this point, the scoring skill of your PNF is
compared with the goalkeeping skill of the opponent keeper. Again, all the
side effects are applied here too.
成功过了后卫后，和门将的PK会决定你的PNF事件成功还是失败，
PNF入球技能会对抗守门员的守门技能，同样的，所有辅助效果都会纳入计算。
We know how much you love statistics, and that’s why we will give you a
taste of PNF.
我们知道大家有多乐爱数据，所以下面会提供PNF的一些数据。
We ran a few simulations with real matches. In every case, the ratings of
home and away team were identical. Same with all the players’ attributes.
The home team was the one with the powerful players. The Powerful Forward had
titanic (15) playmaking and scoring skill. The opponent defender had titanic
(15) defending skill and the keeper had extra-terrestrial (16) goalkeeping
skill. In every match type (with 1 or 2 PNFs against 0 to 3 central
defenders), we ran 3000 simulations and got the following stats:
我们跑了一些模拟，每个案例的主队、客队评级完全一样，球员能力也完全一样，
不同点是，只有主队有力量特技球员。
力量前锋有威力无边(15)组织以及威力无边(15)入球，
对手的后卫有威力无边(15)防守、守门员则有超凡脱俗(16)的守门，
每种比赛类型(1~2个PNF对抗0~3个中后卫)跑了3000次模拟，数据如下：
– Win/Tie chances.
– Average home goals.
– Chances to get at least 1 PNF event.

get at least 1 PNF event in 3000 simulations
And what about the case with 3 PNFs? We are aware how much you love the stats
and transparency, but we also know how much you love to do your own
researches. That’s why we left the last case out of our blog post to let you
find more about it. Good luck and see you on our next dev post
等等，怎么没有3个PNF的数据 ? 我们知道大家有多渴望数据和透明度，
但是我们也知道大家有多喜欢自己研究数据，所以我们留了三个PNF的部份给大家研究。
祝好运！下一篇开发者博客文章见！
