White to move and win (difficult) - Alexey Troitsky, 1897

rustyfish @lemmy.world - 2.1yr

Queen H1 to F1?

Edit: I’m still an idiot.

Pg2

Edit: Apparently I'm being downvoted by somebody who doesn't understand white starts on row 1

Qd3 Pg3 Qf5

wahming @monyet.cc - 2.1yr

Qd3 Bg3 I think, followed by promotion

2
dreadgoat - 2.1yr

I think the definitive solution was already found further down the thread, but I think this could still work
Qd3 Bg3 Nf4 Kh4 ... at that point it becomes a sloppy chase but White takes an indomitable lead, taking B and a pawn easily

1
wahming @monyet.cc - 2.1yr

Bg3 is a check, followed by black promoting their pawn to queen

1
dreadgoat - 2.1yr

Oops, you're right. I went kingblind

1
jafea7 @lemmy.world - 2.1yr

That's what I would have thought, leaves the King nowhere to go and there's nothing to block/capture the Queen.

3
wahming @monyet.cc - 2.1yr

Black is moving down, Pg2

4
jafea7 @lemmy.world - 2.1yr

Doh! My bad, 40+ years since I played.

I'll shut up now 🤐

3
Bytemeister @lemmy.world - 2.1yr

Pawn to G2?

3
SnokenKeekaGuard @lemmy.dbzer0.com - 2.1yr

Bc6 Rb2 Trying to mate on g2 and defending.

I'm not sure where to go from there, either bg2+ or nf4+

Either case I can't find a forced mate in my head atleast

5
Bonifratz - 2.1yr

Good start. You don't have to calculate all the way to mate in that line, White gets an overwhelming advantage.

But more interestingly: What do you do after Bc6 Rb1+?

5
SnokenKeekaGuard @lemmy.dbzer0.com - 2.1yr
  1. Bc6 Rb1+

  2. Ke2 Rxh1

  3. Bg2+ Kxg2

  4. Nf4+ Kg1

  5. Ke1 g2

  6. Ne2

3
Bonifratz - 2.1yr

Perfect, you found it!

3
SnokenKeekaGuard @lemmy.dbzer0.com - 2.1yr

No way!

1
wahming @monyet.cc - 2.1yr

Does it work if black declines to take the queen?

2
Aussiemandeus @aussie.zone - 2.1yr
  1. Bc6 Rb1+

  2. Ke2 Rxh1

3.Bg2+ Kxg2

4.Nf4+ Kg1

5.Ke1 G2

6.Ne2#

Edit K for knight to N

4
Aussiemandeus @aussie.zone - 2.1yr

It appears I'm an idiot too

I'm very new to chess annotation and i keep using k for knight and king.

4
apotheotic (she/her) - 2.1yr

I think it's meant to be Ke1 G2 as Ne1 is an illegal move but that's just a notation issue

3
Aussiemandeus @aussie.zone - 2.1yr

Yeah it was very late i was meant to be asleep not playing chess puzzles knight starts with a k haha

2
wahming @monyet.cc - 2.1yr

It seems to be open ended if black doesn't take queen, though

2
Aussiemandeus @aussie.zone - 2.1yr

Bishop moves to g2 checkmate of it doesn't check the king.

If it does then the king walks back towards the rook. Until it takes it or the rook doesn't check the king ending the game

2
wahming @monyet.cc - 2.1yr

What about Rb2, Kd3, Pg2?

2
Aussiemandeus @aussie.zone - 2.1yr

It gets all very messy if black doesn't take the bate it seems

2
Bonifratz - 2.1yr

In what position? After 1. Bc6 Rb1+ 2. Ke2 Rb2+ 3. Kd3 Black doesn't have anything but spite checks. And if ...g2, White can now safely go Qc1 with quick checkmate to follow via Qh6+ (since g2 is covered by the bishop).

2
Aussiemandeus @aussie.zone - 2.1yr

What's interesting is if black moves to Rf4 and ignores the queen i see how it gets very open ended

2
Bonifratz - 2.1yr

Nicely done! You solved the main (study) line. There's other lines where Black actually holds out longer, but they're much simpler to calculate.

2
wahming @monyet.cc - 2.1yr

What happens if black declines the queen? Too lazy to calculate it out at this point

2
Aussiemandeus @aussie.zone - 2.1yr

Anything it seems. But I'm probably missing a lot

2
Taako_Tuesday @lemmy.ca - 2.1yr

After 4. Nf4+, wouldn't it be better for the king to go to f3? Or am I overlooking something obvious

Edit: answered my own question, white king covers f3 after moving to e2, forgot about that

1
Dsklnsadog @lemmy.dbzer0.com - 2.1yr

I need the reddit bot to try it online.

3
Dsklnsadog @lemmy.dbzer0.com - 2.1yr

Thanks

1
Aussiemandeus @aussie.zone - 2.1yr

King E1 to F1

2
Aussiemandeus @aussie.zone - 2.1yr

No that's no good either, then castle comes to check

2
Aussiemandeus @aussie.zone - 2.1yr

Hang on im still onto it.

New plan

Bc6

Rb1 checking king

Kd2

Rb2 checking King

Kc1

Rook must leave or be taken. Anywhere doesnt matter.

Qg2 checkmate

2
Bonifratz - 2.1yr

Right, but what about 1. Bc6 Rb1+ 2. Kd2 Rxh1?

3
Aussiemandeus @aussie.zone - 2.1yr

Shit. Leave it with me

2
Squareeyed @aussie.zone - 2.1yr

Bc6, Rb1, Ke2, RxH1, BxH1, Pg2, Nf4, Kg3/h4, Nxg2. That's as far as I've gotten

1
wahming @monyet.cc - 2.1yr

Once white loses their queen, a mate is impossible

1
Squareeyed @aussie.zone - 2.1yr

Got a modification on it. I think it works...

Bc6, Rb1, Ke2, Rxh1, Bg2+,Kxg2,Nf4+,Kg1,Ke1,Pg2,Ke2#

? I dunno if my logic is right, but pretty sure that might be it, been fiddling moves for a while...

2
Aussiemandeus @aussie.zone - 2.1yr

Nah thats not true

1
Aussiemandeus @aussie.zone - 2.1yr
  1. Bc6 Rb1+

  2. Ke2 Rxh1

3.Bg2+ Kxg2

4.NF4+ Kg1

5.Ne1 G2

Hows that

6.Ne2#

Edit K for knight to N

1
fosforus @sopuli.xyz - 2.1yr

After which horsie nom noms castle, checks king and black is generally speaking fucked. But that doesn't seem as neat as what they're looking for here.

1
wahming @monyet.cc - 2.1yr

How does horse take castle? Castle is on b1, free queen

1
fosforus @sopuli.xyz - 2.1yr

Oh lol oops. I thought you meant rook to f4 :)

Yeah I'm not amazing at chess.

1
wahming @monyet.cc - 2.1yr

Nvm, turns out that free queen is actually the bait for a checkmate

3
wahming @monyet.cc - 2.1yr

Does it involve Ke2, Pg2, Qe1? Ending with Qc1, Qh6

Edit nvm I'm dumb

2
Bonifratz - 2.1yr

Unfortunately no. After 1. Ke2 g2 2. Qe1 Black has a simple way to win the queen, and after 2. Qc1 Black can at at the very least promote the pawn and there will never be a checkmate for White.
