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.
