classification of chess problems
CT-ART problems are classified two ways: Tactical Methods and Combinational Motifs . There is a dewey decimal type system that divides these into various themes. When one solves the problems by levels, each level is presented by combinational motifs. This pattern is easily discerned once you done a few levels, first comes Knight Forks, then Files (problems you take advantage of that pieces are on the same file, about 2/3 of the way there are Stalemate problems,Pawn promotions etc......... If you own the book Combinational Motifs by Maxim Blokh who compiled the collection of these problems,all the problems are presented by combinational motifs The first 84 problems are Knight forks divided by subclassification Knight forks removal of protection the knight fork decoys. Each subcategory presented in increasing difficulty.
So what exactly is the difference between Combinational Motifs and Tactical Methods?
Blokh writes in the preface of his book "This book is dedicated to a detailed classification by Combinational Motifs -tactical weaknesses in ones position,particular features of piece placement and co-opperation that offer an opportunity to find and to perform a combination. I think there is a benefit to studying an entire classification at one time. ie: doing all the Explotation of a Pin Problems of the various levels to reinforce that theme. Hopefully there is a benefit being to quickly identify that a tactic exists and where the weakness lies in a position.
Blokh published an earlier book entitled The Art of Combination which had many if not all the exact same problems. This was classified by Tactical Method. There was a chapter on Distraction as well as Decoy problems. Distraction and Decoy sound pretty much the same but the finer distinction appears to be in Decoy the opponents piece or King is lured away and captures material then this piece is involved in your tactic
be it checkmate or capture. Distraction the piece is moved so you can attack something else.
I am hoping that learning about the classifications and understanding them will help me improve tactically. Uncertain as to the value but I enjoy doing it. Interesting if others feel if there is value or if it is a waste of time and why. Does anyone know if these classification system was invented by Blokh or if it came from the Soviet School of Chess?
