Concede the point and keep your argument — aunque, si bien, por más que, spoken.
With aunque, the mood is the meaning. Indicative states a fact you accept: Aunque la propuesta tiene fallas evidentes, no podemos descartarla por completo. Subjunctive marks the concession as hypothetical or contested: Aunque tuviera todos los datos, mi conclusión seguiría siendo la misma. The same split runs through a pesar de que and pese a que, while si bien almost always takes the indicative — si bien es cierto, never si bien sea cierto. The C1 move built on all of this is concede, then pivot: es cierto que… pero, ahora bien, con todo.

Carla
Your grammar teacher for this pack
There are no flashcards in the Contract King lessons — you debate, out loud, and Carla takes the other side. She makes a point that's genuinely good, and your job is to name it, grant it — no niego que, concedo que — and then pivot without giving up your claim: ahora bien, con todo, dicho esto, mantengo mi postura. And when you reach for a third aunque in a row, she nudges you toward si bien or aun cuando — because varying the connector, live, is what reads as C1.
Blank mid-sentence and nothing bad happens — she waits. That's the practice, without unnecessary judgement.
Quick answers
When the concession is hypothetical or contested rather than a fact you accept: aunque sea impopular decirlo, Aunque me lo jures, no me convences. For known facts, use the indicative: Aunque el plan fracasó, dejó lecciones.
Almost never — it presents the concession as a given fact: si bien es cierto, never si bien sea cierto. It's also bookish: spoken Spanish reaches for aunque or eso sí instead.
The tilde changes the meaning entirely. Aun cuando = even when/if (concessive); aún = still/yet (temporal). Aun cuando llueva and aún llueve are unrelated sentences.
A purely spoken concession dropped after the main claim — the inverse word order of aunque: Lo lograron, y eso que nadie apostaba por ellos hace seis meses. Most B2 learners never produce it; using it well signals real fluency.
Name it, grant it, pivot: No niego que el método tenga puntos débiles, pero su capacidad predictiva supera a las alternativas. The pivots to learn are ahora bien, dicho esto, con todo, sin embargo — conceding without one reads as concession without conclusion.
