This post is one of my ideas. You may not take it seriously, but I will try to give good advice.Let's go!
"Window" in chess.
If, theoretically, the king can avoid a checkmate, despite the fact that he is on the last rank and a defensive pawn rampart is placed in front of him, then we can talk about a "window". When one of these pawns makes a move forward (preferably one square), a "window" is obtained. There is also an option to protect the last rank (for example, with a rook or a queen), but this option has its drawbacks: for example, the piece protecting the last rank becomes passive. But the "window" has its drawbacks. For example, the chance of a checkmate with a bishop (or knight) and a queen diagonally. And many others.
Also, apart from the moves h2-h3 and g2-g3, there is one more move for the "window" (namely, in short castling), but a weaker one - f2-f3. The first disadvantage is that the king "opens" itself, and this can lead to checkmate. However, there is a plus: if the opponent wants to put a "Stale" checkmate (see the post "Stale checkmate"), the pawn will protect the squares on which the knight must stand before the final move with this checkmate.
Do I think that the "window" is the best defense against a checkmate on the last horizontal? Yes. But with certain moves, namely: h2-h3 , g2-g3, although the last move is in doubt for me.
This concludes my analysis. If you liked it please like it. Good luck to everyone and see you soon!
