Fundamental Checkmates

Today's post is for the total beginner. There are a few important things nobody ever explained to me when first I learned chess. Way up there is the list of fundamental checkmates. I have read several beginning chess books and don't recall ever seeing it, although the closest I've seen is in Kane's Find the Next Move where he talks about corridor mates. Well in my view they all boil down to a few basic patterns.

I hardly can imagine that my work here is original, but if it is well, cool! I don't even know if it could rightly be called a theory, but that's a place to start. Anyway here is my Theory of Fundamental Checkmates:

All normal checkmates are
one of eight patterns.
All double-checkmates are one of five patterns composed of two normal checkmates.






Addendum Mar 4, 2005:

Examples:


This picture shows the 8 normal checkmates using Black pieces instead of capital "X"s.



The next 3 pictures use the same rook mating pattern. In each, the "X" squares are handled differently: first by White pieces controlling those squares, then by a mixture of Black pieces occupying those squares and White pieces
controlling those squares, and lastly by a mixture of Black pieces occupying those squares, White pieces controlling those squares, and the Black King on the edge of the board.

Nicely done.
 
Good thinking. So you are a systembuilder!
 
Glad y'all like it. It's been rattling around my brain for months now, so I really am glad to get it out.
 
I agree very nicely done. In Rapid Chess Improvement, De La Maza comments on creating your own chess visions drills. I thought a good vision drill for me would be to take a look at each potential mate position and determine which squares around the king are attacked(closed) and what squares need to be attacked (open)in order to bring mate. This is a step in the thought process for any solve for mate position. It would be a benefit to quickly determine what squares need to be closed for mate to occur. I may do this at some point with the one move mate patterns in Polgars book.
 
Yes!!! Years ago I noticed many of these same patterns while going through Polgar's massive book. I have been wanting to document them for myself and others, but just haven't gotten around to it. Well done!!

Regards,
Chris
 
Sorry to be such a beginner, but can someone please explain this to me? What happens when the black king moves to the squares with the Xs? Thanks.

PS
 
I see P.S. - X's are unsafe for Black's King - read the "Key" for more info.
 
Then I must be retarded. I have to look it over again tonight because I still don't get it. Thanks KOTS. I'll let you know if I figure it out.

Ahhhhhh! Thanks KOTS.

Good stuff. I find myself wanting stuff systematized as well. Thanks for taking the time to do all this.

Checkmate (frequently shortened to mate) is a situation in chess (and in other boardgames of the chaturanga family) in which one player's king is threatened with capture (in check) and there is no way to meet that threat.

Checkmate (frequently shortened to mate) is a situation in chess (and in other bet basketball boardgames of the chaturanga family) in which one player's king is threatened with capture (in check) and there is no way to meet that threat. Or, simply put, the king is under direct attack and cannot avoid being captured. sportsbook Delivering checkmate is the ultimate goal in chess: a player who is checkmated loses the game (the king is never actually captured – the game ends as soon as the king is checkmated because checkmate leaves the defensive player with no legal moves). In practice, most players resign an inevitably lost game before being checkmated. march madness It is considered to be bad etiquette to not resign in a hopeless situation (Burgess 2000:481). If a king is under attack but the threat can be met, then the king is said to be in check, but is not in checkmate. If a player is not in check but has no legal move (that is, every possible move would put the king in check), the result of the game is stalemate, and the game ends in a draw (but in other variants, it is a loss for the stalemated player). (See rules of chess.)
