i really like chesstempo for training on mating motifs. actually i like not-computer the best because it removes the temptation to think and play one move at a time. but chesstempo is great for doing a bunch of drills on one specific motif to really hammer in the pattern recognition. as far as i’m aware chess.com and lichess aren’t quite as good at being super granular like this

Are there any shortcuts you use that'll make you think "hold on, I think there might be something here"?

Make sure to look at all possible checks! If you do that in this position, you would have to evaluate these moves:

Qe1+ (loses the queen)
Rxh2+ (loses the rook and the bishop, but its mate in 3)
Rf1+ (wins a queen for your rook and your bishop)
Qxf3+ (wins a pawn and trades queens)
Bg2+ (mate in 2)

I know thats not much of a shortcut, since you still have to look at a bunch of moves, but maybe this will help you prioritize which moves to look at first.

EDIT: oops, Rxh2+ is actually mate in 3! I didnt look at the followup after i saw it losing material. shows what i know.

Do you have more pieces around your opponent's king than they have? Look for the kill.

yeah these are the shortcuts OP needed! If you've played enough games, you tell at a glance that Black has a winning move here, even if you don't see it immediately.

The importance of this mission cannot be overemphasized
A good rule of thumb is two more attacking pieces than defending pieces. Here black has a Queen, Rook and Bishop versus just a white Bishop defending the King. That means there is very likely a forced mate somewhere.

As a side note, for spotting Rxh2+, if you play that black has two pieces on white's king and white has no defenders.

How do you improve your ability to recognize mating patterns and good moves in actual games? I've gone through (twice, in some cases) the mating patterns, tactics, and endgame examples on Lichess. I average about 30-40 puzzles a day, review tactics and positions from books, and have tried to work in some YT content on chess tactics and strategy.

But in actual games, at least when I'm not getting crushed, I'm ending up in positions like this:

And just completely blowing it. Instead of the obvious mate in 2, I went Rf1 to get his queen. I ended up missing a forced checkmate 3 more times before finally blundering my queen and losing.

In a puzzle, I know there is a great move buried somewhere, so I'll spend as long as I need to find it. In a game though, even on long time controls I'm never sure if a position warrants more evaluation. Are there any shortcuts you use that'll make you think "hold on, I think there might be something here"?

what was the time control? in blitz/bullet it's more about developing an intuition for it i think. in time controls where you can actually slow down and think more, something like this mate in 2 you can just kinda brute force by looking at all the checks or forcing moves you have, every move, and calculating them out 1 or 2 moves ahead to see if they lead anywhere

:xickos:

and by developing an intuition, i kinda mean you have to learn the basic checkmate patterns, and as you play attacking moves you can be eyeballing the opponent's king and counting how many escape squares he currently has if he theoretically was in check right now, and then you see if you can cut them off and go in for the kill.

like in this bullet game i had the other day, i hadnt fully calculated it out but i had a good feeling that if i sac my bishop by taking the pawn on b5, then i would be able to take back with my knight with check, and then my 2 rooks plus knight with the king kinda wide open like that against only a bishop and bad rook might be enough to hunt around for a checkmate since the king would be pretty trapped in without many escape squares:



and it worked out, the rest of the game went like this
14. Bxb5 cxb5
15. Nxb5+ Kb7
16. Rd8 h6
17. Nd6+ Kc7
18. Ne8+ Kc6
19. R1d6+ Kc5
20. Rd5+ Kc6
21. R8d6+ Kb7
22. Rb5# { White wins by checkmate. } 1-0

I'm pretty sure the word "gambit" comes from chess and made its way out into the wider world. Myself, I find myself saying "intermezzo" instead of "intermediate" pretty often.

Intermezzo is probably more associated with music than chess for most people. But yeah zugzwang is a very cool word. Gambit, stalemate and checkmate all have a fair amount of use out in the world. Endgame, also.

:xickos:

a big thing that helped me start seeing checkmates on the board was realizing that if you attack a king, the two squares kinda diagonal and back from the king are often key escape squares:




and those escape squares are cut off, the kind might be particularly vulnerable to a mating threat. this can be because the king is pushed up against the edge of the board, or it can be because you used something like a rook to cut off a file or a bishop to cut off a diagonal, or often it's just because his own pieces are in the way:




if i see something like those two kings on the board, i'm instantly on the lookout for a quick mate

I saw a thread once that says the 'cheat detected' triggers if the player has a lichess analysis board up in another window of their browser but it is not so sophisticated as to check they were mirroring the current game.

I don't think I understand this Lichess puzzle, possibly because I've only recently managed to work my way this far up (~1900) in my puzzle rating. Materially the solution boils down to "you win a pawn", but it's a full 5.0 points worth of eval at the default depth. What endgame principle am I missing?

Two pawns (after the king moves, you get another) and end up with a passed pawn.

It's kind of a poo poo puzzle because the 'only' move is trivially obvious. The 'point' is that it's a trivially winning endgame, and any move other than the obvious move lets black defend the a-pawn with the king thereby stabilizing.

which is why black's best move is to block with the rook instead of moving the king. but it's a lost endgame anyway

If you're talking about today's "happy birthday Tatev" one, I'm not sure how they're supposed to avoid mate? You can delay it one move by saccing the queen I guess.

I was referring to the Sunday puzzle

The first move seems obvious, grab the hanging piece, but it's impossible to see the continuation from there because the continuation is black making consecutive blunders and throwing the game.

So I'm staring at this puzzle like "Ok white seems to be winning here but... what happens next... what's the trick... how is this a sunday puzzle :confused: "

i think the point there is to find the best move in the position, not necessarily find the complete continuation. the moves are taken from a real game, so while, yes, black blunders mate, if white doesn't find the right second move the game reaches equality and then the continuation to mate (in the actual game black resigned after white's second move)

in the middle of a correspondence game and i worked out a line that seemed to guarantee that i'd win a pawn within 5 moves because of some tactics. almost played the first move to enter the line and did my final check to make sure everythings ok, and noticed atthe end of the whole thing he had a discovered attack that would have won my queen. lol, thats why you always keep thinking
