During the opening you play to establish an advantage.

The endgame is when you realize you are going to lose." - Saviely Tartakower.

Originally posted by Mad Rooki honestly had to goggle it, it seems like its a system for working out the optimum number of moves for a mate using retrograde analysis with six pieces or less on the board, although it must come under fifty moves. I suppose its an area where computers have really advance chess knowledge. I did wonder when i was following two engines play each other, why they were able to calculate so fast near the end, perhaps they were using these table-bases to do so 🙂
Ken Thompson calls it "Playing chess with God." Seems like the perfect description to me.

But they can suck up a lot of hard drive space. A 5-piece set uses about 7 gigabytes of HD, while a full 6-piece set uses about 1 terabyte (1000 GB) of HD. I only use a 5-piece set; I'm not that much a fanatic about them. On the few occasions when I need a 6-piece lookup. I just use the online Shredder database.

And Black is one step closer to nabbing the pawn. If Rb6+ , then Kxp. However, if White moves the king, it could go something like this:
And the pawn finally drops. They would have to know their Q vs R game, but I'm assuming they know that. (Wish I did! ) They would also have to go through numerous variations to ensure that they know the outcome, but I'm assuming they did that too.

it's been the midsummer festival here, which is the biggest holiday in finland. the sun stays up through the night, bonfires are burned, everybody's drunk, and obviously sleeping is not a priority. my brain is still pudding from all that. 3h of sleep last night, so this isn't probably going to go much better...
edit: loads of useless analysis cut out, as mad rook did much better. I should take a long nap now...
