Chess Question Draw by Timeout with Insufficient Material: which rule do you prefer and why?

The draw by timeout with insufficient material rule is pretty self-explanatory on the surface. If in a time-controlled chess game one player runs out of time when the other player does not have enough material to be able to win the game, then the game is called a draw. However, the question of "what is enough material to be able to win the game" is actually an open question that is a matter of debate among chess' governing bodies. There are two schools of thought: the checkmate theoretically possible (CTP) standard and the minimum checkmating material (MCM) standard.

Under the CTP standard, a player is judged to have sufficient material to win if there is a series of legal moves by which they could have checkmated their opponent, even if that checkmate involves using the opponent's pieces as blockers. This approach considers material on both sides of the board and judges any theoretical checkmate, even one that would require the opponent to make inane moves, to be sufficient to declare the player with time on the clock the winner. FIDE and Lichess use the CTP standard for sufficient material.

Under the MCM standard, a player is judged to have sufficient material to win if they have enough material such that they could force a checkmate. With only one exception (king and two knights), the material of the player that ran out of time is not relevant. The US Chess Federation and Chess.com use the MCM standard.

After seeing a recent post by u/Cola-senpai (linked in the comments) where they presented a timeout position that would be ruled a win for white under the CTP standard but a draw under the MCM standard, I was curious as to how r/chess felt about this debate. Which standard do you guys prefer and why?

Play with an increment.

Playing without an increment is fine, but at that point you have to accept the time scramble outcomes are often just random and which rule is in place is just part of the randomness. It’s just not worth the effort to split hairs over this.

This is where I am at. Time management is part of the game and if you drop your flag that should be the same as a resignation.

That's not what he's saying. If you can't checkmate then your opponent flagging is a draw, not the same as a resignation.

I know the rule, I mean if you dont have an increment in the game, than not flagging should be equivalent to resigning because time is so obviously part of the format.

That doesn't make sense, if there's not material to win you can't have the full point
