The pawn isn't going anywhere and if Qxh5 then Black forks White's King and rook. winning a pawn and the exchange

Planning Rh8, but even that doesn't win the Bishop or White's H-pawn. This was probably what Black had been relying on with Rg8.

Ruling out Rh8.

A bit aimless. I should have taken the time to lay down a better attack, rather than repeat the position.

?? Simply losing the rook. Better would have been Rg8.

Black can't take the d-pawn because of Qh3+ winning the Bishop and, likely, the queen. Actually it looks as though there is a forced win in all the variations I am seeing.

Originally, I had planned on simply taking the Bishop, but here I began to see more forcing moves.

No good choices here.

It seemed that from here I could win both the Queen and the Rook.
