How does integrating polymorphism with the strategy pattern enhance the design of move validation in a chess system?

hard📝 Trade-off Q9 of Q15

LLD - Design — Chess Game

AIt forces all pieces to use a single fixed validation method

BIt allows each piece to select and switch move validation algorithms dynamically at runtime

CIt removes the need for inheritance in the piece hierarchy

DIt makes move validation static and compile-time bound

Step-by-Step Solution

Solution:

Step 1: Understand polymorphism and strategy pattern
Polymorphism enables objects to behave differently through a common interface; strategy pattern encapsulates algorithms.
Step 2: Apply to move validation
Each piece can hold a reference to a move validation strategy that can be changed dynamically.
Final Answer:
It allows each piece to select and switch move validation algorithms dynamically at runtime -> Option B
Quick Check:
Strategy pattern enables flexible algorithm swapping [OK]

Quick Trick: Strategy pattern + polymorphism = dynamic move validation [OK]
