1. Rf2 Kg3
2. Nd2 Kg4
3. Nf3 Kg3
4. Ng1
if 4 .. h2 then 5. Ne2+
if 4 .. Kh4 then 5. Rf5 h2 6. Nf3 Kh3 7. Rh5+
White wins.
1. Rf2
Okay, I’m stumped. This is a typo, but … for what?
1. Ra1 h2 2.Ra2+ Kg1 3.Kf3 h1Q+ (or any other piece conversion; on h1N simply 4.Rb1) 4. Kg3 and white wins.
Correction:
..on h1N simply Rb2….of course
Thanks to silman, I’ve got this one cold.
The key is:
1 Ne5! Kxh1
2. Kf2 Kh2
3. Ng4+ Kh1
4. Kf1 h2 (only move)
5. Nf2#
The pawn makes mate possible!

1. Ra1 h2 2.Ra2+ Kg1
After 2…Kg3 or 2…Kh3, Black escapes with a draw.
3.Kf3 h1Q+ (or any other piece conversion; on h1N simply 4.Rb1) 4. Kg3 and white wins.
That’s not right, either: 4.Qh8 draws.
You are right that 1.Ra1 h2 2.Ra2+ Kg1 loses.
1 Ne5! Kxh1
2. Kf2 Kh2
2…Kh2 does lose, but 2…h2 draws.
Well, fudge. Back the board I guess. Brad H.
Depends on who is playing. If it’s Carlsen, Radjabov, or Aronian….they will play for the win. If it’s Anand, Topalov, or Kramnik….they would have agreed on a draw a long time ago.
Rh2 Kxh2 Kf2 Kh1 Ne3 Kh1 Nf1 h2 Ng3 mate
oops that doesnt work
I think i have it now
Ra1 h2 Kf4 h1=Q Ne3 Kh2 Ng4 Kg2 Ra2 if kh3 then Nf2
if Kg1 then Kg3 and Ra1mate
oops he has qh8 after kg3
now i have it….i think
Rc1(i think Rd1 also works) h2 Kf4 h1=Q Ne3 Kh2 Ng4 if Kh3 then Nf2 and if Kg1 then Kg3 with Rc1 coming
And yes if Kf1 then Nh2 and wins if ke1 then Rc1 and if Kg1 Then Kg3
now i have it….i think
Rc1(i think Rd1 also works) h2 Kf4 h1=Q Ne3 Kh2 Ng4 if Kh3 then Nf2 and if Kg1 then Kg3 with Rc1 coming
Very nearly exactly right, except that 1.Rd1? doesn’t work:
1.Rd1? h2
2.Kf4 h1=Q
3.Ne3+ Kh2
4.Ng4+ Kg2
5.Rd2+ Kf1
is drawn. This doesn’t work in the main line:
1.Rc1! h2
2.Kf4 h1=Q
3.Ne3+ Kh2
4.Ng4+ Kg2
5.Rc2+ Kf1
… because of 6.Nh2+ (among others).
Sorry – Rc1 does not work. After Rc1 black has
1…Kc1
and there is no mate.
Stalemate here, stalemate there… annoying 🙂
Sorry – Rc1 does not work. After Rc1 black has
1…Kc1
and there is no mate.
How can black play Kc1?? Rc1 is the only winning way for white others draw.
Using best moves it is a mate in 18 moves.
after 1. Rc1 black has 3 possible moves 2..h2 / 2..Kg3 / 2..Kh2
if he plays h2 is mated in 17 moves
Kg3 mated in 8 moves and finally Kh2 mated in 5 moves
ok I’ve got it.
1.Rc1 h2
2.Kf4 h1=Q
3.Ne3+ Kh2
4.Ng4+ Kg2
5.Rc2+ Kf1
6.Ja2+ Kg1
7.Kg3
I can’t see the win. Is it a draw because once you allow black to queen, can he keep checking you in the next move if you do not take the queen with Ra1xh1?
Anon 11:23 –
1.Rc1 h2
2.Kf4 h1=Q
3.Ne3+ Kh2
4.Ng4+ Kg2
5.Rc2+ Kf1
6.Nh2+ Kg1
7.Kg3
… is a win because Black can’t do much about 8.Rc1#. He can stall with a spite check 7…Qxh2+, but after 8.Rxh2, White mates shortly.
