Queen H1 to F1?

Edit: Iโ€™m still an idiot.

Pg2

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

Qd3 Bg3 I think, followed by promotion

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

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

I'll shut up now ๐Ÿค

Pawn to G2?

[-] SnokenKeekaGuard@lemmy.dbzer0.com 5 points 1 year ago* (last edited 1 year ago)

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

[-] Bonifratz@feddit.de 5 points 1 year ago

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+?

  1. Bc6 Rb1+

  2. Ke2 Rxh1

  3. Bg2+ Kxg2

  4. Nf4+ Kg1

  5. Ke1 g2

  6. Ne2

[-] wahming@monyet.cc 2 points 1 year ago

Does it work if black declines to take the queen?

[-] Aussiemandeus@aussie.zone 4 points 1 year ago* (last edited 1 year ago)
  1. Bc6 Rb1+

  2. Ke2 Rxh1

3.Bg2+ Kxg2

4.Nf4+ Kg1

5.Ke1 G2

6.Ne2#

Edit K for knight to N

[-] Aussiemandeus@aussie.zone 4 points 1 year ago

It appears I'm an idiot too

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

[-] apotheotic@beehaw.org 3 points 1 year ago

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

[-] Aussiemandeus@aussie.zone 2 points 1 year ago

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

[-] wahming@monyet.cc 2 points 1 year ago

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

[-] Aussiemandeus@aussie.zone 2 points 1 year ago

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

[-] Aussiemandeus@aussie.zone 2 points 1 year ago

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

[-] Aussiemandeus@aussie.zone 2 points 1 year ago

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

[-] Bonifratz@feddit.de 2 points 1 year ago

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).

[-] Bonifratz@feddit.de 2 points 1 year ago

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.

[-] wahming@monyet.cc 2 points 1 year ago

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

[-] Aussiemandeus@aussie.zone 2 points 1 year ago

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

I need the reddit bot to try it online.

[-] Aussiemandeus@aussie.zone 2 points 1 year ago
[-] Aussiemandeus@aussie.zone 2 points 1 year ago

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

[-] Aussiemandeus@aussie.zone 2 points 1 year ago* (last edited 1 year ago)

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

[-] Bonifratz@feddit.de 3 points 1 year ago

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

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

Edit nvm I'm dumb

[-] Bonifratz@feddit.de 4 points 1 year ago

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.
