I have read that in using unreal conditionals, irrespective of personal pronouns, it mandatory to use subjunctives to form verbs.

" If Jack was playing they would probably win " - if I am correct, the verb 'was' should be replaced by the subjunctive 'were'.

I have taken the above sentence from a famous English Learning Website. Please let me why this sentence is correct ?

  • Welcome to the site! That's true, you should use were in that sentence. But many people sin against this rule, native speakers too, so there's your explanation. – Cerberus_Reinstate_Monica Mar 7 '15 at 18:06
