Full Counterfactuals - Past-Unreal Chains
The past-unreal conditional from Module 10 - the changed past, a regret - is the engine of the full counterfactual: αν + PLUPERFECT in the condition, θα + PLUPERFECT in the result, with θα ONLY in the result. «Αν είχα διαβάσει, θα είχα περάσει» (“if I had studied, I would have passed - but I didn’t”). Both verbs are είχα-series pluperfects; the lone θα is the whole difference between “I had passed” and “I would have passed”. At B2 you CHAIN them - one imagined condition unrolling into several would-have results, each its OWN θα + pluperfect, strung by και: «Αν είχες έρθει, θα με είχες δει και θα είχαμε φάει». A negative condition works identically: «Αν δεν είχα φύγει, θα σε είχα βοηθήσει» (δεν negates the pluperfect condition; the result stays θα + pluperfect). Keep BOTH halves in the pluperfect and put θα on EVERY result clause, never on the condition.
