Answers
1. hadn’t gone (When we use would have + past participle in the main clause, we have to use a past perfect tense in the if-clause.)
2. will have (This is a type one conditional sentence. In a type 1 conditional sentence, we sometimes use should in the if-clause to suggest that something is less likely.)
3. Either ‘see’ or ‘should see’ (In a zero conditional sentence we use a present tense in both clauses. These types of sentences are used to talk about situations that are always real or possible. Should see is also possible here. The structure If…should is used to suggest that something is possible but unlikely.)
4. will play (When the verb in the if-clause is in the present tense, we use will + infinitive in the main clause.)
5. should be (After I and we, should can be used with the same meaning as would.)
6. was (When we use would + infinitive in the main clause, we have to use a past simple tense in the if-clause.)
