when the flag falls, its usually over, with very few exceptions (one being, the opponent did not pay attention, then someone wins, and THEN they look at the clock..)
draw by position requires a position where no one CAN win. Here, white and black can both queen a pawn if the other side makes a mistake. No draw.
Chess tournament rules are available online so you can go read them. You won't find anything about a4.
If Black's flag falls in that position, he loses the game. White has a pawn and can make a queen and force checkmate.
Theoretically, Black could simply move his King aimlessly on the kingside and allow White to capture both of his pawns and win the game.
Great answer Maxieman! No time no claims game over!
that is exactly what I said.

Sorry for resurrecting this topic but by USCF rules (and chess.com) this is a draw, correct?
FIDE Laws of Chess:
"6.9
Except where one of Articles 5.1.1, 5.1.2, 5.2.1, 5.2.2, 5.2.3 applies,
if a player does not complete the prescribed number of moves in the allotted time, the game is lost by that player.
However, the game is drawn if the position is such that the opponent cannot checkmate the player’s king by any possible series of legal moves."

You mean Caruana, So, Nakamura... play by different rules from Carlsen, Nepo, MVL, Karjakin...?
That makes no sense.
It's about FIDE and USCF tournaments (and differences between chess websites rules).
I know that Lichess uses FIDE rules and Chess.com doesn't.
No website implements the FIDE Laws of Chess correctly. To determine "the opponent cannot checkmate the player’s king by any possible series of legal moves" is difficult for any software.
Yep, probably. I think the big issue is about "forced mate" vs "possible mate". KNN v K is automatic draw in Chess.com but not in Lichess with FIDE rules.
What I would like to know is how the rule of USCF considers the promotion of pawns to assess whether the material is insufficient or not.

So when So plays Caruana in the US Championship, they play according to different rules than when they play each other in a FIDE tournament?

This is stupid: Americans, French, Russian... each playing to their own rules. In any sport or game there are international rules that apply to everyone. FIDE should always prevail. If the implementations in software are only approximate because of too difficult, that is another story.
Here is an endgame, in G/3 time variant, you just claimed the win when you opponents flag/or his time ran out, he says it is a theoretical draw, but he has 2 pawns and his king and I have a pawn and a king. I thought, when someone'stime ran out you lose, but he says he claimed the draw, no matter what, what chess rule book doe he reads?
Position after flag fell/or time ran out: there was no DRAW offer before the game started or even before his time ran out.
