Sorry, at move 141, when Black plays c12, I cannot find a peep at p14. There is a peep at m18, but I can't follow what you are saying.
The bot says with c12 it's still very confident of a black win, but bots can play out a close endgame accurately, whereas going for a more decisive pressing of advantage to reduce chance of a slack yose loss could be wiser for a human. Hard to balance the risks involved.
Well, they can play out a close endgame accurately, and, OC, they ordinarily do. But that depends upon accurate reading. At move 141 I kind of doubt that is the case, without very powerful hardware. Consider the last gainful play in this game, Black 289. The game record gives a variation where Black plays a 0 pt. sente first, and the bot gives Black a winrate estimate of 90%.

OC, there is nothing wrong with the play, but even at this stage of the game the bot's evaluation sucks big time. That does not inspire confidence. (Not a komi mismatch problem, either, as White wins with a 7,5 komi, too.)
