This is my first foray into the Sicilian from the perspective of black.
So I'm messing around with the open Sicilian on my engine, in particular 4 ...Qb6 5 Be3 Qxb2.
In this variation, apparently even if the queen takes the rook in the corner, by move 9 or 10 the engine recommends giving back the exchange.
Can somebody explain why it's best to give it back?
Cheers!
