How should I set the rule for a 1 vs 1 game?

Hi folks.

I have a board game, there are 2 players in a game and they are opponents against each other.

How should I set the number of teams and players for the rules?

Type 1 :

{
"Name": "All",
"TeamCount": {
"Min": 1,
"Max": 1
},
"PlayerCount": {
"Min": 2,
"Max": 2
}
}
]```

Type 2 : 

```"Teams": [
{
"Name": "All",
"TeamCount": {
"Min": 2,
"Max": 2
},
"PlayerCount": {
"Min": 1,
"Max": 1
}
}
]```

+ Do both of these rule structures work?
+ If they are correct, which one is the best structure for this kind of game?

I also checked the [rules samples](https://docs.unity.com/ugs/en-us/manual/matchmaker/manual/rules-sample) page, but I coudn't undertand fully.
The sample 1 vs 1 => Team count 2 player count 1 
The sample 5v5 => There are Team Red and Team Blue, each ones teamcounts=1 player counts:5

What is difference between to create teams (red and blue) and the TeamCount rules?

Thanks a lot.

No comments or opinions?

Hi, thank you for your question. There are no real difference between the two options you provided. Both will end up with the same result

Hi @guillaumedUnity , thanks for your reply.
For this project your answer will be enough, but I read the documentation and watched many videos but I couldn’t solve this question: “What is difference between to create teams (red and blue) and the TeamCount rules?”
Maybe I missed some document page or video about this topic, can you share any source about this?

You would use team that are named if you need to specifically identify the teams. For example in a in a asymmetrical match for example, or if a specific team is supposed to defend, or if specific rules are applied to a given team.
You would use team count when all the teams are exactly the same. A team battle royal is a good example of that.
