SUMMARY

The chess problem discussed requires White to achieve checkmate in two moves. The optimal solution involves the moves 1. c7, followed by either 2. Rxa7 or 2. Qc8, depending on Black's response. The discussion highlights the importance of understanding the en passant rule, as Black's last move must have been b7-b5 to allow for this scenario. Participants also reference retrograde analysis, a technique used to deduce the previous moves leading to the current position.

PREREQUISITES
  • Understanding of chess rules, particularly en passant and checkmate conditions.
  • Familiarity with retrograde analysis in chess problem-solving.
  • Knowledge of basic chess notation and piece movements.
  • Ability to visualize chess positions and potential moves.
NEXT STEPS
  • Study advanced chess tactics, focusing on checkmate patterns and strategies.
  • Learn about retrograde analysis techniques in chess problems.
  • Explore the en passant rule in-depth and its applications in various scenarios.
  • Practice solving chess puzzles that require multiple moves to achieve checkmate.
USEFUL FOR

Chess enthusiasts, problem solvers, and players looking to enhance their strategic understanding of checkmate scenarios and retrograde analysis techniques.

I agree... Too bad I can't find any.

Only one possible solution - I assume this has been already solved:
pxp ep kxa5
rxa7 mate

It has been solved... And your answer is mostly right...

Kxa5 is not possible. The pawn at a5 is the one that was used for the ep so the move is Ka5 not kxa5. So as I said its mostly right :biggrin:

I know I am being picky, but peoples misunderstanding of en passant is annoying me

Do I have to be a paying member? That's pretty annoying.

what if 2. b3+ Kb5? or KxB?

2... Kb5 is not a legal move because the Bishop is now at a4 and attacks b5.
2... KxB is not a legal move because the King is now at c4, and the Bishop at a4, two squares away.
If, however, you mean 1... KxB, this case was handled by quark in message #40 of this thread.
