Damn, I saw bishop takes and then rf1+ I didn't realise you could castle

The general rule for puzzles is that you can always castle if it looks like you can, unless there is explicit text saying otherwise.

I remember seeing a puzzle that, due to the position, either side could castle but if one side castled it meant that retroactively the other wouldn't have been able to.

Can you clarify what that was like? I'm having trouble understanding.

I saw this puzzle as well.

A side can castle unless there is evidence that they can't.

In the contrived position only one side could castle. If White was able to, it meant black couldn't and vice versa.

The solution to the problem was white castling to create check. White was also able to just move the rook to create check.

If White moved the rook, there was no evidence that black could not castle, and so on asubsequent move could castle to avoid mate.

However, if White castled there was evidence and black was no longer to escape mate.

I wish I could find the puzzle, too. It really was exceptional.

the castled rook would block the king from castling

I remember that one, it was a total brain bender.

Very satisfying to finally understand it all (eventually!)

Ah yes, the classic O-O-O-O-O-O

Reading 0-0-0-0-0-0, I thought it was from chess960

2
zeekar1100 chess.com rapid•

Too many 0's. In 960 the king must be between the rooks, so there can be at most 5 empty squares between the king and a rook.

Hm, can you castle in 960 with a rook that's closer than 3 squares away?

Yep I saw the first move, but didn't think to castle so got stuck for a bit!

i was thinking of rook but took me 10 minutes to realize its a castle

Remove the counter. The first queen-save puzzle on this subreddit. We had a good run.

I posted one before ;) but this is way better

Think it’s >!Bxf7+ Kxf7 O-O+ Kg8 Qxb4!<

mnkb99•

Ooof that was beautiful! I got stuck trying to make >!Bg5!< work

6

!Bg5!< isn't saving whites queen at all, it's just counterattacking blacks. The problem with that, in this puzzle, is that whites queen isn't defended as the knight on c3 is pinned.

xHelios1x•

!Bxf7 Kh8!<

Hartog_•

Then just Bxe8, problem solved

Black loses too much material. White just kind of wins after the queen trade

14
theacidbat101Knight in shining armour•

yeah then just take the rook

LilamJazeefa•

Note: We're forced to assume that the White king never moved and then moved back. Then castling would be disallowed

Few people use the Returned Bong Cloud opening.

Those people are known as cowards.

3.Ke1 allows 3...Ke6! and black has more central squares with no wasted tempi developing his king.

That’s how puzzles work.

Otherwise every puzzle would have to explicitly allow it, or deny it, or show you the moves for the entire game.

2
LIN88xxx•

Most puzzles show you the move for the entire game

badatnamingaccount•

Most puzzles only show you one move prior, to indicate which players move it is.

  1. Bxf7+,Kxf7,0-0+ move queen away bc now unpinned

Queen can even take the black bishop after that, thus not even losing a piece.

In fact white is now up a pawn

I'm a new player. How do you know how far to play out puzzles like this? I stopped at around the previous person's comment as well.

1
Melodicmarc•

There isn't an exact rule on how far you should play out this puzzle, but I just would keep going until the tactics run out. I think the best advice I can give you is look for clues. The two things that alerted me were 1. That bishop is undefended, 2. The queen has x-ray vision on the bishop. I think recognizing things helped me see this more than just trying to visualize 3 moves ahead.

2
teeceli•

awesome. thanks!

1

When white castles to remove the pin, why wouldn't black just take the queen with their rook? I think I am missing something...

2
Sylvais•

Castling comes with check because the black king is now on f7

😳 Crap, I missed that one... Thanks for clarifying.

Sylvais•

No problem :)

3DotsOn2Geckos•

If it’s a tactic for white, why not post from white’s perspective?

27
Direct_Dot_2232•

It's useful to look at things from different perspectives, I guess. Also I think they just posted from their game and they were black.

17
lightningfootjones•

Bf7+. If Kxf7, O-O+. If Kh8, Bxe8 👍

14

If Kh8, I would Qxe8 and force the queen trade too

-1†
aradil•

Chess engine a few moves after that doesn’t show much advantage for forcing the Queen trade versus taking the material; they aren’t going to trade Queen for bishop. Still lots of mobility for white after that.

giants42102300 Rapid, 2200 Blitz Lichess•

The point isn’t that it’s the best objective move. When up a piece it’s generally easier to play without queens on the board.

-1
aradil•

I mean you can trade down to less pieces when winning and that’s often a sensible strategy to move towards end game, but in this case there is significant positional advantage for white, and you have so many options for safely activating more pieces, taking material, threatening other pieces safely, setting up a potential fork, etc…

There is a reason the engine says they are roughly equivalent moves; trading queens here wouldn’t be a bad move, but the alternative is really good too.

OldWolf2FIDE 2100•

Me too. You're up by a piece and 2 pawns and your king is a bit exposed, trading queens is a no-brainer

1
m_ninepoints•

OK can I just say, if the puzzle is white playing, can we stop posting puzzles where white is on the far side of the board?

6
maxifer•

It's to simulate the feeling of helplessness while playing as black in a winless scenario.

2
Oh_Tassos •

I got Bxf7+ and Kxf7 but I'd never ever see O-O+, for some reason in my mind castling = pure defence, no checks, no attack, no nothing

Silentarian•

Definitely the same. This changed my perspective on what castling could be used for!

I analyzed the image and this is what I see. Open an appropriate link below and explore the position yourself or with the engine:

My solution:

Hints: piece: >!Bishop!<, move: >!Bxf7+!<

Evaluation: >!White is winning +8.44!<

Best continuation: >!1. Bxf7+ Kxf7 2. O-O+ Kg8 3. Qxb4 Be6 4. Qd4 Rb8 5. Be3 Rxb2 6. Rf3 Rb7 7. Ne4 Bd5 8. Nc5 Ra7!<
