Well, I got in 1 second this time! Wish I could say it was brilliant insight rather than just the ability to remember something for a week or so.

What exactly are the black knights and pawn doing?

Mate in three:

1. Be6! threatening 2. d5#.

If 1. … Qxd4 2. b8=N#.
If 1. … Qh5 2. b8=N#.
If 1. … Qd5 2. b8=N#.

More generally, if Black moves the Queen off the 8th rank, then 2. b8=N# since Black can't check the White King from off the 8th rank.

So we now only need to explore Black moving the queen to either a8 or d8 to prevent 2. d5#. (Note that 1. … Qg8 won't prevent 2. d5# since the White Bishop interferes, as it's now on e6.)

If 1. … Qa8+ 2. bxa8=Q#. (or 2. bxa8=B#.)
If 1. … Qd8 2. b8=N+ Qxb8 3. d5#.

D.Harika (from my country) played well in the olympiad even though Padmini Rout scored better.I have a soft corner for Harika who is about 8 years older than my grand daughter Niharika who is not a chess player.Since we do not have any new puzzle today ( if Susan permits me to do so) I quote here a position Harika had in the olympiad.

I never thought chess is so dangerous.2 casualties in one event is too much.

I find somehow the message goes twice.That is because of "Robot protection text" which says "your text does not match" but actually the message had already gone once.
