played ( badly) 10 years as white

Very nice.

The thing about the puzzle you just solved is it shows just how difficult endgames are and that you shouldn't give up unless all hope is lost. As long as the position is unbalanced, keep attacking and you'll nick the odd result you should never have got.

I think that puzzle is a cracker. The idea of playing Ra1 is cheeky like when you promote a pawn to a knight for a mate.

Most satisfactory.

was the answer the same line or little bit different ?

was a great puzzle & finding rook a1 a realy strange move , goes against everything we want to do

playing themed tourneys help understanding values of pieces & sacking them , plan to arrange a tourney at my club sometime with themed game like mad gambits ie Lopez counter-gambit, Jaenisch variation & Giuoco Piano: Therkatz-Herzog variation

[Tal]

I played the Jännisch for a few years a while back (for everyone else, it's a sharp counter to the Ruy Lopez: 1.e4 e5 2.Nf3 Nc6 3.Bb5 f5). Brought it out for one game a couple of seasons ago and got a nice draw against a strong county player.

Not seen a published answer from Carlsen, but that definitely works and there won't be multiple solutions.

when the rook goes to the corner square to block the black pawn, why doesn't blacks king take the rook?

when the rook goes to the corner square to block the black pawn, why doesn't blacks king take the rook?

The short answer is White will block the king in and trap him in the corner. This means black can only move the pawns forward, leaving white able to queen his c-pawn and win

Now, here's the trick. If Black plays d6, white must not take that, but instead play c6 and push past it. The reason is that, because we have trapped the king in, we will create a stalemate for a draw. Whoops!

[titaniumbean]

knew it would be something simple sigh.

on his facebook page they say Re4 Kb5 & c4 , not checked this & not sure it works ? taking e3 buys a move , Rxe3 first move draws , other thing want to check is Re4, Rxe3 followed by Rb3+ , the trouble here is that the c pawn needs to be on 5th rank to promote

[curnow]

Cristobal König 1. Re4 Kb5
2. c4+ Kb4
3. c5+ Kb3
4. Rxe3+ Kb2
5. Kd3 a2
6. Re2+ Kb1
7. Re1+ Kb2
8. Ra1! Kxa1
9. Kc2! a4
10. Kc1 a3
11. Kc2 d5
12. c6 d4
13. c7 d3+
14. Kxd3 Kb2
15. c8Q a1Q
16. Qc2++

this is on the facebook page but
1. Re4 Kb5
2. c4+ Kc5!! draws ( edit : dont think it saves it )

[Tal]

Thought we'd put this to bed (I'm not one for analysing hands to death on PHA and I'm very much the same in chess puzzles!)

If someone does actually find the answer, please feel free to post it here!

[Tal]

I'm pretty sure Kc5 draws so it looks like it's back to the drawing board, unless someone can make it work for White.

 



In non-puzzle news, David Howell has crushed the field in the British Championships and is a point and a half clear with the last round today, thereby winning the title with a round to spare. He plays second seed Gawain Jones today.

Worth a play through, chaps and chapesses.

David Howell maintained his 1½ point lead with the top boards all drawing, so he finished on 9½/11, which is a heck of a total against what remained a competitive field.



There's a fair bit of controversy over the Qatar 2022 football world cup and whether the players and fans will cope with the conditions.

The Chess World Cup starts tomorrow in Tromsø, Norway. It's right up in the Arctic Circle, so the players will be somewhere where it will barely be dark for the entire time they are there.

Here's a report:
