1. Bh3 (stops Qxh2#) Bxh3

2. Rf2 (frees f1 because of 2..Bg2+)  Bxh2 (still threatening Bg2+ and a later discovered check)

3. Rc3 (protects g3, now Bg2+ hangs the bishop, while before Bg2+ led to Qg3+ and mate) 3... Bf4 (still allows influence before the Knight has to move to e5, Bg2+ discovered check is still the threat)

4. Rxh3 Qxh3+ (self-explanatory, stops Bg2+)

5. Kg1 e3 (threatens winning a rook with check, the pawn is defended twice)

6. Rg2 (maintains protection of h2 from the queen) Qh4 (threatens Qe1#)

7. Nxe3 (stops the mate threat by allowing the block) Qe1+

8. Nf1 Ne5 (brings the Knight for f3+ to draw the King away from defense of the Knight)

9. Qc8 (sets up the eventual block/pin on h3, frees the pawn to take the Knight if it invades to e5)

9.. Be3+ 10. Kh2 (h1 hangs the knight with check, and protects the queen when it moves to h3)

10.. Qh4+ (taking the knight now leads to Qh3+ and then a discovered attack on the Black's queen once Rxg7+)

11. Qh3 Bf4+ (forces loss of the rook otherwise the King cant protect the White queen anymore)

12. Rg3 (blocking with the knight allows Ng4+, again forcing the King away from Queen protection) Bxg3+

13. Nxg3 Ng4+

14. Kg2 Ne3+

15. Kh2 Ng4+

16. Kg2 Ne3+ and so on and so on.

Deviating from this perpetual check allows either the loss of the Black queen due to the pin, or the White Knights invasion to f5 and then d6, when creating the passed pawns on the queenside causes more problems for black.  Since black is stuck making perpetual check with the Knight, it's a draw.

You mean Bxe3...Qxe3. 

So not a draw.

It's hard to play for a draw.

1.. Qxh3 means the queen will be put in danger after Rf2 and Bxh2.  The mating net isn't set up properly then.

Pawn to h3 loses to Bxh3, setting up pins and forks throughout

White has to deal with the black mating threats first before he can even address a4/a5.

Anyone who thinks this isn't a draw isn't seeing Black's threats properly.

why is this a draw?!

I do not get this puzzle at all

Was this from a practical game or just a puzzle?

This one is so far the hardest daily puzzle I have ever seen

Fantastic Game Saving. Nice. :)

 Thanks for attempting to explain, but I'm still scratching my head.  It strikes me that even the way it's played out as you've shown, there could be a white pawn promotion, with white knight assistance.  It's just over my head.  But hey, an occasional puzzle like this is good!  2400 players are people too!  LOL!

not able to make sense of it

This puzzle was very hard for me but I enjoyed the challenge!!!!!! 

The puzzle ends with like half the game left.
