This is indeed a common choice, as En Passant usually occurs within the first few moves of the game, and since you have 50 moves left before being asked to make a choice, you're not forced to make subsequent captures. In this case, En Passant is the only move that keeps the game going, so if you want to continue, you must capture both pieces. In short, this is an option, or rather, a forced option
Forced en passant?
Sort:
¿En serio? La captura al paso no es forzada. Una vez jugué una partida contra alguien con dos oportunidades de captura al paso, y no las usó (en lichess) y ambas oportunidades se perdieron. Así que la captura al paso no es forzada. Si crees que fue solo porque no sabía la captura al paso, veamos este ejemplo(todos son hipotéticos):
Aquí, ¿es forzada la captura al paso o hay que mover el rey? Mostre todas las jugadas posibles, y ninguna es al paso. Si crees que es por el jaque, aquí tienes otro ejemplo:
Este movimiento permite la captura al paso. Ahora, muestro todos los movimientos de captura posibles. El segundo es al paso. Pero el hecho de que el tablero de análisis me permita capturar sin forzar captura al paso debería ser prueba suficiente para demostrar mi veredicto final y la verdad definitiva: la captura al paso no es forzada.
en passant is not forced
i think
Thanks for the answer, ThrillerFan.
SallyVIII, you should look up the definition of "troll." Legtimate questions about chess rules do not constitute trolling. Calling someone a troll, however, very well might.
Interestingly, this question was debated during the 19th century, according to Wikipedia. It was Howard Staunton, an English master, who definitively answered that the move IS required. If anyone has a source on some of the debate, I should like to see it. It has always occured to me that en passant is a choice, and as such, cannot be compelled.
It is a choice by normal occurrences as En Passant is usually in the opening few moves and as you have 50 other moves to U are not compelled to take and forfeit doing so on subsequent moves. In this scenario it is your only move that keeps the game going and so you need to take as the white moved two squares. Its either a choice or your forced.
