Si me hubieras pedido...

[Quaeso]

I wanted to make a contrary-to-fact conditional saying:
If you would have asked me yesterday, then I would have been able to do it (give someone a ride across town)(earlier today).Is this correct grammatically?
Si me hubieras pedido ayer, yo lo habría podido hacer.

[poli]

Yes, that's right. In Spanish the conditional corresponds with the past subjunctive. Be aware that you can also say yo pudiera hacerlo instead of of yo lo pudiera hacer.

Si me hubieras pedido ayer, yo lo habría podido hacer.It may sound better this way:
«Si me lo hubieras pedido ayer, podría haberlo hecho.»

[Quaeso]

Be aware that you can also say yo pudiera hacerlo
I think that would be for a present contrary-to-fact whereas I wanted a past c.t.f.

[poli]

Pudiera hacerlo and lo pudiera hacer are synonomous. The difference is a matter of the speaker's choice.

[Quaeso]

Yes, thank you, but what I mean is that for a past contrary-to-fact, I think it should be: yo hubiera podido hacerlo.
