By far the best I’ve calculated in a game: an 8 move sequence that ended in me getting a back rank mate



9. Qxd5 Qb4+, then 10. c3 Qxb2. So here’s the trick: instead of moving my rook out of danger, I play 11. Bd3, preparing it for a killer blow in a couple of moves. Then comes ..Qxa1+, 12. Ke2 Qxh1.


Oh no, my rooks!

13. Qxf7 h5, 14. Qe8+ and black’s only move is to block the check with Nd8. And *chef’s kiss* I have my light squared bishop, that I moved several moves ago, ready to go 15. Bf5+, forcing the black king back to b8, so I could play Kxd8#.


….aaaaand of course the computer is a total dick about my beautiful Bd3 move, because of course it is



E: actually analysing the game there a few ways black could have stopped the sequence :cripes:

christ knows, i was expecting Qa1 or Qc1.

If they’d played Be7 instead of h5 they’re still winning, because it means that the knight will be covered when it comes in to block a check

i don't normally have problems with chess.com puzzles, but it's kind of bugging me that this puzzle:

https://www.chess.com/puzzles/problem/775094


white to move

and this puzzle:

https://www.chess.com/puzzles/problem/1548240


white to move

are given essentially the same difficulty rating. got them back-to-back. one took 5 minutes of calculating various lines to get the solution, the other took me 20 seconds, the majority of which was spent thinking "it can't possibly be that simple". i think their random puzzle creator/evaluator is on the fritz

yeah one of those is ~2200ish, the other is... 1200ish? tough to give it a rating because every chess.com puzzle under 1800 is a back rank mate

I'd say more like 1700/500

If you're just doing rated puzzles they do throw a variety of ratings at you, and you get better rating gains for successfully solving ones higher than your own rating etc. But I think it's supposed to be within a certain range of your own current rating so yeah :iiam:

The importance of this mission cannot be overemphasized
If you look at the stats, that second puzzle has had only about 1300 attempts, so is fairly new. The ratings take a while to normalise (they are dynamic based in the pass/fail rates of players at different elo, not set in stone by the creator) so for recently added puzzles the rating can be higher or lower than it probably should be.

wait, then what are puzzles with a "pending" rating even for if they still dynamically rate the puzzles after they're rated?

when doing a puzzle rush i just keep clicking on a major piece and then the back rank as quickly as possible and it just always gets you passed, like, the first 15 puzzle

Pending rating means the number of attempts are below the threshold where they even assign it a base elo. Not sure what the threshold is.

I've started doing puzzle rush recently, and man do they really love the pattern where the enemy king is on B8/G8 behind two pawns and you have a queen and a rook lined up on C7/F7. I get about 6 of those per rush.

Castles roosting on an open file
Black knights nipping at your pawns
Wayward queens being hung without trial
On chessboards like manicured lawns
Everybody knows a queen and bishop in a row
Help to make opponents sweat
Tiny clergy in their fianchetto
Will find it hard to dodge the threat

They know that bishop's on his way
To pin them to a rook and take them away
And that weakened king is gonna wait
For a pawn and queen in a lobster-pincer mate

Now I'm offering this simple phrase
To players from 300 to 2070
Although it's been played many times, many ways
Don't push f6 or f3

The best mating pattern is Philidor’s mate with a Queen on the long diagonal and a Knight on g5/c4. Knight check, then double check, then a Queen sacrifice, and then a smothered mate.

I’ve seen it in a thousand puzzles and will never see it in a real game.

I think the rating of the second one might be inflated from people falling for the red herring of the rook capture and not seeing the obvious winning move

I thought I never would but then got two of them within about a week. If you are attuned to it you will see the necessary elements of the pattern in the game.

Also, I've had it once where the opponent let me checkmate him a couple moves early (moving the king to h6 instead of h8 after the double check) instead of retreating into the corner to allow the queen sac and smothered mate. Not sure if he just gave up or was denying me the satisfaction on purpose.

Is there such a thing as an annotated interactive endgame trainer? I'm sure there are great books but no matter how detailed, it's hard to beat being able to play a move and seeing "ohhh the tablebase does this, that's why it doesn't work". But for sites I've found like https://chess-endgame-trainer.firebaseapp.com, it presents you with a bunch of positions where you kind of have to guess and the only moves are mystifying if you don't understand them. If someone could say for a given position "you need to control this random square / push this random pawn /triangulate the king because XYZ" it would be the best of both worlds.

Endgame feels like the hardest part of chess to learn through spontaneous online play since many games will end early due to tactical battles leading to mate or large material imbalance, and of the games that reach a reasonable end game often someone's in time pressure. Meanwhile most of the learning material (beyond basics like opposition) focuses on specific worked problems or technical topics (eg. Lucena position) which isn't that practical, at least at lower skill levels.

...But I could hardly wait six months with a red hot jape like that under me belt.

I started teaching my girlfriend chess. It's been super interesting to really try to think about the best way to break it down and teach it, and, as a 1000 ish blitz player, I am learning a tonne by trying.

First, we covered how the pieces moved then we did a game, with her playing both sides and talking about the possible moves.

Next, after some research, I found this amazing video from Yasser explaining why the pieces are worth what they are (hint: it's how much control they have on their best squares, which I didn't know!) https://www.youtube.com/watch?v=YDw8yfeUiBg

What should I teach next? Has anyone got any basics videos as beautiful as that one?
