Nf1 h3+ ( 18... f5 19. a6 bxa6 20. bxa6 ) 19. Kxh3 Ne5 20. a6 Nd7 21. axb7

I don't understand the reasoning behind 18. Nf1, taking it back to the edge of the board?

Why wouldn't you play 18. Nf5, threatening 19. Nd6 and forking both those pawns?

You are free to move any other. This is just a schematic study without computers analysis, to show a principal, what happens, if blacks avoids a draw

And you don't need computer analysis to tell you that moving a Knight to the edge of the board is a bad idea, unless you have a good reason.  That's taught in beginners chess 101.  You must have a reason for cutting your Knight's places to move in half so explain your rationale for 18. Nf1

Halp.  I need an explanation of all the moves in this one in small words.  Gutartas' variations might prove enlightening given four or five days of study, but then again maybe not.

iouioooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo

sorry i was just testing something

I only know I know nothing

This was tough to do, tough to understand even with gutartas' analysis.

how is this a draw withpawns on a4/a5

Cannot be a draw

Pretty sure this isn't a draw....Anyone care to work this out further?

Clearly White's first move has to avoid checkmate... Options being what?

bishop to h3
pawn to h3

Anything else? I think King to g1 will result in a win for black...Having looked that over closely but that is my first hunch.

What is black's next move if playing for a win?

wut...ummm...WUT?!

Tough

Why not 1. .. Qxh3 ?!

nice

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.

Why not 7. Bxe7+

You mean Bxe3...Qxe3.

So not a draw.

It's hard to play for a draw.
