If I knew you were in casino last night, I would have joined you. Conditional formatting type 2.
Hi, Tony—That conditional is not type 2 and is not correct. Type 3 is needed:
- If I had known you were in a/the casino last night, I would have joined you.
In what other situation/circumstances do we use past future tense (would have).
"Would have" is generally used when making counterfactual inferences with reference to the past, as is done in type 3 conditionals:
- If I had been there, I would have seen her.
- If I had had a million dollars, I would have bought that house.
- If he had paid his bill, they wouldn't have shut off his power.
