I'm not at all disagreeing with the existing answers - both sound. Indeed every pawn is a potential queen. However, one aspect of the question remaining is: why struggle for a pawn as opposed to a ...

Can a pawn move 2 spaces if doing so would cause en passant mate?

Can a pawn move 2 spaces if doing so would cause en passant mate? Of course! There are no rules which forbid blundering mate in 1, even forced mate in one.

One amazing game I know that ends in a pawn mate in one called The Polish Immortal in which Black sacrifices all four minor pieces to win the game! The pawn does a double-step to give the mate. [Title ...

How did a pawn appear out of thin air in “P @ e2” after queen capture?

You were playing the chess variant called Crazyhouse. In this variant you can place pieces you captured, as one of your color anywhere on the board, instead of a normal move. I don't know the software ...

Would there be more decisive games if we began to see stalemates as checkmates? And hence more "interesting" chess?

Absolutely not. Making stalemate a win would be a sure way to make for less interesting chess. Any rule change which makes it easier to convert a small material advantage to a win, will ipso facto ...

There is no loophole. Rules 3.7.1 to 3.7.4 allow pawns to move forwards along the same file, or diagonally forwards onto an adjacent file. The only argument here seems to be that "forwards" is not ...

Why do I need to notate the file when capturing with a pawn?

You seem to want the notation to be as efficient as possible, disregarding ease of use. Let's take this to extremes: If White only has a single move or capture that ends on c4, then instead of Bc4 or ...

There is no real reason, it's not technically necessary. Equally, you don't generally have to write the 'x'. Knowing where the piece is going is enough to know that it's a capture. People must have ...

The chess.com engine didn’t show a checkmate

As White's previous move was pawn on h2 to h4 then pawn g4xh3 is a legal en passant capture. For more info - see Rule 3.7.d of the laws of chess

Why is c4 a better move in this position?

White intends to play c5, which will gain space on the queenside and severely cramp black's position (The b6 knight has no good square). On the other hand, e5 weakens white's control over d5 and f5 (...
