A critical middlegame position has arisen. Black has just played a clever looking move Ra8-e8 with the idea to exchange queens after Rxh4 and Rxe2. Black wants to use white's weak back rank, for example after 1.Qf3 there follows 1...Re1+ and the curtains are down for white. But if white agrees to exchange queens with Rxh4 then black plays Rxe2 and controls the second rank. Are there perhaps better options?
