How to choose between a move "that's playing for a win" vs a "solid move"?

I often hear on streams and analyses that in a position "White can play g4 here, but that's playing for a win" so instead the GM suggests some knight relocation or something less sharp.

I know this is expecting GM level play from both sides, but this style of thinking is more influential in classical time controls than blitz and, since I have a long time control tournament coming up, I'd like to understand this concept a little further.

I don't have a board example for the line above, but if we imagine a position where a GM claims "g4 is playing for a win" while suggesting a more solid move for White, when should White "play for a win" and when should White "play solid", assuming White sees both ideas?

My Guess:

Solid Move - Defined as a move, opening, or manner of play that is characterized by minimal risk-taking and emphasis on quiet positional play rather than wild tactics.

"Play for Win" - I think this is defined as a sharp move (risky, double-edged, highly tactical) that is expected to give Black the opportunity to at least equalize with perfect play. (Meaning not every sharp move always has this expectation)

So the factors in deciding between the candidate moves would be:

• Time on your clock
• Time on opponent's clock
• How you value the game's possible end results (depending on opponent ELO or tournament standings)
• How comfortable you are with positional play vs sharp play
• Both your ELOs - you may expect a GM to survive the attack with an advantage, but could you survive it?
• Other minor influences (how you think your opponent will fare under pressure, whether or not you feel tilted, if you may want more time to rest before next round, etc.)

These are all outer influences, we're assuming you've calculated and assessed possible positions to the best of your ability, but you're having trouble deciding between the 2+ candidate moves.

What are your thoughts? Do you think my "Play for Win" definition fits? How would you decide between the two ideas and why?

I have heard of these terms.  But usually what happens with my games is i will think about the Solid move, and the Play for a win move, and will occasionally throw in some thought of the "What would <inset GM here> play move.  In the end i play the Wrong move.
