> for time-beating purposes, it is optimal to instantly guess as soon as you identify that a guess is necessary

Often that is the case, but sometimes you reach a point where you ultimately need to guess, but you can make an informed guess based on the number of mines remaining. Then the question becomes, is it worth guessing and potentially losing faster, or are you having a really good game and want to risk losing late in the game?

Wait, there's a timer involved? I always ignore those.

The optimal strategy is to fail-fast.
