Friday chess puzzle 7
This week's Friday chess puzzle is from Tigran Petrosian vs. Boris Ivkov 1979. The position is quite well known, so apologies if you've seen it before.
The question is: how did Petrosian, White to play, force a quick checkmate?
Rxd4, to which black has to take with either pawn or rook, then the Re5+, forcing the Kxg4. That would be the longest, most painful route for black. Yes?

Rd4 Taking Bishop. Pawn or Rook takes Rook.
Re5+ (Taking pawn if it is still there)
Kg4 Taking Knight (forced)
h3++
I think this is correct, I am not posting with my computer.
I'm also inclined to think that -
