Clarifying a football incident
The user’s Chinese sentence describes a situation in a soccer match: "The referee blew the whistle when the Henan team had a one-on-one because Cardoso was offside on the back pass first." They might be looking for clarification on this incident from a game in the Chinese Super League. In soccer, if a player is offside during a teammate's back pass, it counts as offside. But, if it’s a back pass from an opponent, offside rules don't apply.Analyzing offside in soccer
I’m considering the phrase "卡多索回接越位在先," which suggests that Cardoso was in an offside position when he received a backward pass. "回接" indicates he came back to receive the ball. Offside is called if, at the moment the ball is played, he’s in an offside position. This means that even if he retreated, he was still offside when the pass happened. The referee stopped play because Cardoso was offside, but some referees might allow play to continue for an advantage.Reviewing offside rules
I'm looking into the IFAB Laws regarding offside, and I realize there's no advantage on an offside call. Play should stop immediately when an offside offense occurs, unless the non-offending team has a clear chance to play the ball quickly. I find that Law 11 clarifies that if a player in an offside position receives the ball from an opponent's deliberate play, play may continue until the player becomes actively involved. The assistant referee will raise the flag, and the referee will stop play—no advantage applies in this case.Clarifying offside conditions
I'm considering a scenario where a teammate who isn't offside receives the ball later. While this isn't directly relevant, the user seems to be seeking confirmation with their statement and "对吗？". Since they didn’t ask a specific question, I can respond clearly by either affirming or explaining the law. If Cardoso was offside when his teammate passed the ball, then the offside call stands. I should clarify that retreating to receive the ball doesn't reset the offside, and if the ball was deliberately played by a defender, then it wouldn’t be offside.Explaining the offside call
It's important to clarify the phrase "单刀被吹停," which means that once an offside occurs, the referee typically does not apply the advantage principle and stops play immediately to prevent further issues. They might delay raising the flag if they're uncertain about who touched the ball first, which could lead to a moment where it looks like a breakaway for Henan, but it would still be called back. If the ball was deliberately passed back by an opponent, then it wouldn't count as offside. A useful check is to consider Cardoso's position relative to the second-to-last defender at the moment the ball was played. I’ll craft a concise Chinese explanation for clarity.
大致判断思路是对的：如果卡多索在队友传球瞬间处于越位位置，随后“回撤接应”并触球/干扰对手，就构成越位。按规则一旦越位犯规成立，主裁不会给进攻方所谓“优势”，应当立即吹停，所以即便河南队随后形成单刀，也会被叫回。
需要注意的两个关键前提：
- 判定时刻看的是队友出球瞬间的位置；回跑拿球并不会“洗掉”越位。 
- 若球是由对手“可控的故意触球”（非解围性挡救）传到卡多索脚下，则不算越位。
想确定本次判罚是否准确，核心就看：队友出球瞬间卡多索是否越位、以及球到他脚下前是否存在对手的“可控故意触球”。如果是前者而无后者，吹停成立。
