It is white to move. How should white proceed?
R(7) - g4 ... they say
I might be missing something better, but 1.R1g4 looks very strong, and it is an easy move to spot because of the attack on the a4 pawn- hard to defend that otherwise. Black can exchange the queens with 1......Qd3. Not sure this is best- Qf5 looks worse to me, but is more complicated and I could easily be missing something.
