LENDER COMBINATIONS

I tested Grok3 on the day of its public release. I asked Grok3 to define Lender Combinations.

Grok3 - was on spot. On first try! It came up with the best description I can think of.  Here it goes:

 DEFINITION: Lender Combinations refers to a specific concept in chess composition, named after the Israeli chess composer Baruch Lender (1913-1994).

Who is the author of Lender Combinations?

- Baruch Lender: He was an Israeli prolific chess composer who introduced a novel idea in chess problems known as "Lender Combinations." In 1979, he published a two-mover that for the first time combined the themes of Reversal and le Grand, showcasing a unique blend of chess problem themes where a key move was reversed from the typical approach of attacking or covering a square to moving a piece away from it.

What is Lender Combinations?

- A Concept in Chess Composition: Lender Combinations is the name given to a chess problem theme where the key move involves moving a piece away from a square instead of towards it, thereby combining the themes of Reversal (where a move is done in an opposite manner to what's expected) and le Grand (which involves a thematic paradox). This combination was innovative because it introduced a new way to construct chess problems by exchanging the key and threat with mates in both passes. Despite its originality, this composition didn't gain immediate recognition in chess problem tournaments, but over time, the concept became known and named after Baruch Lender.

Note: The term “Lender Combinations” does not relate to any financial or lending practices but is strictly within the domain of chess problem composition.

THE MYSTIC OF LENDER COMBINATIONS

 

THE MYSTIC OF LENDER COMBINATIONS

Mysticism in Chess Created by Baruch Lender: The Single Idea That Changed Chess Composition Forever.

This is a blog about the great mind behind the Lender Combinations.

One of the most interesting combinations in chess composition is the one with reversed key.

 The idea of reversing a key is simple: instead of moving a piece to attack or to cover a square, we can move it away from the square.

The novelty was introduced by the now famous Israeli chess composer Baruch Lender, (1913-1994). It was published in1979 as a two-mover showing, for the first time, a combination of exchanged key and threat with mates in both passes.

According to the definition this is actually the combination of themes: Reversal and le Grand.

Despite the originality of thematic paradox, his composition was not adequately rewarded in tourney, and therefore this new combination remained unnoticed for a while.   

The only consolation for the inventor is if the invention becomes recognizable by his or her name as was the case with the “Reversal+le Grand” blend which is nowadays known as the Lender Combinations.

The recognition and the glory came many years later by many other chess problems.

Discussion:

The question posited: is it a Combination or a Paradox?

One answer was: Reverser Grand Contradiction. This blog points to - around the rare but amusing and fascinating series of moves that surprisingly looks like they shouldn't work.

Is the idea of exchanging the key in chess a combination or a paradox? In my opinion, it is an innovative combination. How did I reach this conclusion? A key's objective of duties is to defend a specific square. The key moves with the intent to attack and/or defend a receiver of threat from an enemy piece positioned on a particular square. If we move the key away from that original square leaving an exposed square, thus creating a threatening mate if we don’t

In the a publication (On the Threshold of a New Era in Chess Composition), we discovered that there are only 9 key-definitions.

We have shown that by combining these keys with different threats, it is possible to build many new types of combinations.   In fact, all of the chess combination themes are based on this idea.

In future blogs we will explain this point by showing how a specific key-definition may be combined with a threat to create new types of combinations.  We will show that only one or two themes are needed to create all other types of combinations.
