Just looked at Greenpawn's latest blog.
Very good (as ever) with humour and instruction.
There were quite a few comments like n--nn and it's a draw.
I'm certainly not accomplished enough to recognise when a game is a draw this far out.
I was wondering in these situations,how many moves in advance one has to calculate to reach this conclusion?
Obviously it will differ from game to game but generally speaking?

Do you know the abilities/qualities of your opponent?

@hells-caretaker saidI suppose you get a "feel" for your opponents abilities during the game so the answer is yes.

One thing I do know is that you can't take any notice of the current ratings on here but that's another issue.
As for how far I can see -not very far I'm afraid unless I use the analyze board and try stuff which I don't really like to do as I'd rather play as if I was OTB

@venda saidSometimes no calculation is necessary at all. For instance, technical endgame knowledge can make one aware of the draw, regardless of moves.

For example, give White a dark squared bishop and an a-pawn to go with his king, and place Black's king on a8. No matter where the the White king and bishop are, we instantly know the position is drawn simply because of the position of the Black king- White's bishop is the wrong color.
In rook endings with rook and pawn vs rook, knowledge of the Lucena position and the Philidor position also allow an easy assessment of win or draw with only a quick glance at the board.
Sometimes calculation is needed, but knowledge of technical endings is an easy shortcut.
@venda saidAs Paul said, it’s seldom about calculating moves in advance, though there are simplified positions (kings and pawns only) where counting tells you who promotes first.

It is much more about recognizing patterns and fields of force.
Reti recounts an anecdote as follows: several strong players were analyzing an endgame position in the anteroom of a tournament, moving pieces about and trying to find the winning line — that is, the typical amateur’s thought-mode of calculating move by move forwards. Reti relates that Capa came into the room, barely glanced at the board, then arranged the pieces in some quite definite position and said “This is the winning position.” Reti was stunned and of course Capa was right. The point being, you often have to think backwards in chess: once you see what the winning position is, you fill in the gaps how to get there later. Kasparov makes a similar point in his book Deep Thinking.
And yes, GP’s blog is terrific. One of those elementary patterns one must know, like the Lucena position or Philidor’s famous mate with a queen sac on g8 and a knight move to f7.

The blog challenge I give myself, find a good OTB game then RHP
examples is enjoyable. Often I stumble over wee gems for a later date.
Saying an ending is a draw is easier and often more correct than declaring
a middlegame drawn. I'm on safe ground if it is a technical draw which should
be known or picked up along the way as you go along without ever studying endings.
Technique can be taught and memorised. When you show a beginner how to mate
with a King and Queen, that is technique. After mastering it they could mate Carlsen.
As for seeing ahead. Here (white to play)
You count the pawn moves, spot the skewer, then visualise the final mate.
The final mating pattern which can appear on any edge square.
You are seeing, at a glance, about 15-16 moves ahead.

@greenpawn34
In a position like the one diagrammed, counting, rather than trying to visualize I-go-here-he-goes-there-then-I-go-HERE-and-he-goes-THERE, is essential. With white to move, it is four to promotion, also four to promotion for black--which means that the white queen will have the move and black's king will be on the same file as black's new queen. Skewer! No need to calculate the rest.
However, if black to move, then black promotes first and can move the newly promoted pawn (Q) first, checking the white king instead of vv. Elementary counting, no wizardry involved.

At the top of the screen there's an icon which says Blitz. Try clicking on it.
