By the way, though... the daily puzzle you have on there is from GK.... is that allowed? |

shadowreaper... To get an idea of these check out some of the forum threads on this site - there are quite a number that discuss the endgame, exploring this or that strategy, and looking at types. I think there is (or was) a rook ending thread, and some time ago I started one called 'Creativity in endgames'. Having looked at your rating, I'm not sure what that might mean, but it does suggest to me that it is worth looking at some technical elements of the ending - the sort of thing beginners need to learn to develop their game. A 'Beginners' Corner' style of thing, to go with, but separate from, the more advanced stuff. Just about any beginner can win with K-and-Q vs K - but even here there is room to discuss how to avoid a stalemate. For instance, suppose White found himself in this position: w White is in check from the rook, which is itself is unprotected and 'en prise' to the Queen. Why should White not take the rook? How do you win K-and-R vs K endings? In my brief period coaching kids at primary school, I was surprised how few could nail such a simple win. But for anyone starting out, it is still something that has to be learned. Here's an example: White to play and win. w Or this one: White to play. Can Black win? w In the following 4 positions with White to play, how should the game end? 1/- w 2/- w 3/- w 4/- w You might well know, but a lot of beginners might not. Good luck with your chess blog. It has the potential to become a very useful resource for developing players. Cheers, Ion |

K plus Q vs K plus R w In this endgame, Black, with desperation - or diabolical cunning - has played 0... Rf7+! Black's hope is that White will indeed snap up the loose rook: 1.Qxf7?? Stalemate! Draw! So what should White do about it? Can he win, withal? 1.Kg6 ... Now, check out all the rook moves that are not check. All of them lead to Black's King being checkmated in a move or two: (1...Rb7, 2.Qc8#; 1...Rc7, 2.Qxc7 and mate next; 1...Re7 2.Qc8+ and mate next; 1...Rf8 2.Qh3+ and mate next; 1....Rf6+ 2.Kxf6 Kh7 3.Qg4 and mate next; Any other rook move on the f-file leads to 2.Qc8+ and mate next. All that is left is: 1...Rg7+ 2.Kf6 ... And Black is almost as badly placed as before. You can check out the non-check rook moves, the most plausible being: [a] 2...Rg1 3.Qc8+ Kh7 4.Qc7+! Kg8 (else any move on the h-file leads to 5.Qh2+ winning the rook; interposition leads to mate on the spot) 5.Qb8+ Kh7 6.Qa7+ wins the rook on g1; or [b] 2...Ra7 3.Qc8+ Kh7 4.Qh3+ Kg8 5.Qg3+ Kh7 6.Qh2+ Kg8 7.Qg1+ and picks up the rook. In these lines there is no danger of Stalemate. 2... Rg6+! It's no good going back to f7, check, as White can take with the King, and mate next. 3.Kf7! ... Again, all non-check rook moves lead to mate in one or two moves. And 3...Rf6+ 4.Kxf6 Kh7 5.Qf7+ Kh6 6.Qg6# So... 3...Rg7+! 4.Kf8! ... And Black runs out of resources. Neither check helps (4...Rg8+ 5.Qxg8#; 4...Rf7+ 5.Kxf7 Kh7 6.Qh4#) and any other move on the g-file leads to a quick mate (a special case is 4...Rg4 5.Qxg4 Kh7 6.Qh5#!). Black might try 4...Rc7 Hoping for a rash capture (5.Qxc7?? Stalemate). There's nothing better for Black. 5.Qh4+ Rh7 6.Qd4+ Rg7 7.Qg7# By the way, not all Q versus R endings are as 'easy' as this one. In some circumstances it can be very difficult. But I think you do get a bit of a picture of resources for attack and for defence in even quite 'simple' (in the sense of there being very few men remaining) endgames. Cheers, Ion |
