1 of 2

I don't have all the details, but I think the answer is something like

1.Qa4, Rxf3||Rh5 (Rook has to move or it will be lost after Queen trade)
2.Qa6+, Qxa6
3.xa6+, K?? (Not sure if capturing the pawn or moving to a8 or c6 is better) 4.Ba3, (Start developing pieces, immediate threat is handled)
