Look at these examples to see how third and mixed conditionals are used.
We would have walked to the top of the mountain if the weather hadn't been so bad.
If we'd moved to Scotland when I was a child, I would have a Scottish accent now.
If she was really my friend, she wouldn't have lied to me.

Grammar explanation
Do you know how to use third and mixed conditionals?
Third conditionals and mixed conditionals
Conditionals describe the result of a certain condition. The if clause tells you the condition (If I hadn't been ill) and the main clause tells you the result (I would have gone to the party). The order of the clauses does not change the meaning.
If I hadn't been ill, I would have gone to the party.
I would have gone to the party if I hadn't been ill.
Conditional sentences are often divided into different types.
Third conditional
The third conditional is used to imagine a different past. We imagine a change in a past situation and the different result of that change.
If I had understood the instructions properly, I would have passed the exam.
We wouldn't have got lost if my phone hadn't run out of battery.
In third conditional sentences, the structure is usually: If + past perfect >> would have + past participle.
Mixed conditionals
We can use mixed conditionals when we imagine a past change with a result in the present or a present change with a result in the past.
1. Past/Present
Here's a sentence imagining how a change in a past situation would have a result in the present.
If I hadn't got the job in Tokyo, I wouldn't be with my current partner.
So the structure is: If + past perfect >> would + infinitive.
2. Present/Past
Here's a sentence imagining how a different situation in the present would mean that the past was different as well.
It's really important. If it wasn't, I wouldn't have called you on your holiday.
And the structure is: If + past simple >> would have + past participle.

Hello Abhay,
The first sentence tells us that the person formed an erroneous opinion. I'm guessing the context here is cricket, so we can imagine that the person is a batsman facing a spinner. He expects a certain degree of turn and is surprised that the ball does not deviate so much. This sentence tells the story of an error by the batsman.
The second sentence introduces a hypothetical or speculative sense. We don't know if the batsman thought about it, but the speaker is speculating that if he had thought about it then he would have expected more turn. This sentence could have a more general meaning as well: it could be about the expectations of the team captain before the match (at the coin toss), when the captain is trying to assess the pitch. In that case it would have the sense of '...as much as he would have thought when he made his decision to bat first'.

Thanks Peter.
You are right that cricket is the context here :)
I understood the difference but I still have some doubt on "would have" usage. I have seen this construct being used for different sentences having different meaning. For example :
1. "Had I had enough time, I would have completed the task" - So here task was not completed for sure.
2. "He would have been very nervous before his speech" - Here we are not sure if he was nervous or not ( AM I right ?). If I am right then this somewhat contradicts with above example of "would have" where we know for sure that task was not completed.
3. Indirect form of "He said, he will have done it by evening" is "He said he would have done it by evening " -> so here we are just reporting directly what a person said. Does this "would have" have different meaning ?
Thanks again!
Regards,
Abhay
Hello again abhaykumar,
1. That's right. This sentence describes a hypothetical past, as you say: I didn't have enough time, so I didn't complete the task.
2. Yes, that's right. The speaker here is speculating about how he felt. It has a similar meaning to 'I expect that...' This use does not contradict the first sentence; rather it represents a different use altogether. Remember that each modal verb can express multiple meanings (e.g. could can express past ability, present speculation, present possibility etc) and the same meaning can be expressed by multiple verbs (possibility can be expressed by could, may, might etc).
3. The shift from will to would here is not about the modal verb but the context of the reported speech. We can leave the very in the original form if he statement is still true. For example:
Thus, 'He said he will have done it by evening' tells me that it is not yet evening; the statement is still true. On the other hand, 'He said he would have done it by evening' does not contain this information. It may not yet be evening and it may still be true (possible), or it may already be too late.
I'm guessing you're an India fan so congratulations on another fine win over the Aussies :)

Thanks Peter. This really clarified my doubt on this.
And Yes I am Indian fan. Thank you :) - The first question I asked was based on commentary I heard during this match. You are good guesser :)
Hi,
Why did we use "wasn't" and not "weren't" in this second conditional sentence?
If his house wasn't so far from the office, he'd bike to work every day.
Thanks
Hello Laura3000,
Both 'was' and 'were' are possible in these sentences. It's an example of the language changing: 'were' used to be much more common but 'was' is becoming more and more popular.

Hi, I have a question please
What is the difference in meaning for below statements?
If Italy qualified at world cup 2023, they would win the world cup
If Italy qualified at world cup 2023, they would have won the world cup
If Italy had qualified at world cup 2023, they would win the world cup
If Italy had qualified at world cup 2023, they would have won the world cup
and is it correct to (at) world cup or I should say (in) world cup?
Thank you so much indeed
Hi Amani Sweidan,
It should be ... qualified for the World Cup (the structure is qualify for X, if X is the competition that they successfully reached e.g. They qualified for the final / They qualified for the Olympics).
Let's take the sentences one by one. The key question here is - When is this person speaking (i.e. is it before or after the qualifying? And before or after the World Cup?)
It's complicated but I hope that helps to understand these structures!

Thank you so much Jonathan for your detailed answer,
So, at the moment (While the qualifying is already finished, and the World Cup has not finished yet!) which structure is correct to use from the 4 sentences?
I believe this one,
If Italy had qualified for the World Cup 2022, they would win the World Cup
Am I right!
Thanks again
Hi Amani Sweidan,
Yes, right :)
