Sep 8, 2023 at 14:20 comment added Joel David Hamkins I suggest we call it simply the minimal move instead of the "do-almost-nothing" move or the "almost passing" move, as the latter are cumbersome and not more descriptive than "minimal". But those phrases do seem fine to help motivate the question.

Sep 7, 2023 at 21:20 comment added Noah Schweber @PeterTaylor That makes me feel better, I thought you meant "quick human calculation."
Sep 7, 2023 at 21:16 comment added Peter Taylor Perhaps I should have said "computation" rather than "calculation". My program gets up to $6 \times 11$ in a few seconds, but didn't get as far as $14 \times 14$ in six hours.

Sep 7, 2023 at 20:37 comment added Noah Schweber @SamBenner Neat! I've incorporated these facts into the question itself.
Sep 7, 2023 at 16:50 comment added Sam Benner $6×19$ doesn't work, but $6×27$ does.
Sep 7, 2023 at 16:26 comment added Sam Benner Other than $2×n$, $6×11$ is the smallest example, and $6×15$ the next smallest. I'll let you know when my computer reaches $6×19$...
Sep 7, 2023 at 15:28 comment added Noah Schweber @PeterTaylor Embarrassingly, I'm not seeing it; what's the quick calculation? (Maybe my coffee hasn't kicked in yet ...)
Sep 7, 2023 at 8:04 comment added Peter Taylor Your memory appears incorrect, but if we assume you misremembered $\max$ for $\min$ some quick calculation shows $6\times 11$ as an example.
Sep 7, 2023 at 1:50 comment added Noah Schweber @SamHopkins Oh indeed! That argument is my all-time favorite proof in mathematics, by the way, partly for nostalgiac reasons: it (circuitously) played a non-negligible role in getting me into logic.
Sep 7, 2023 at 1:41 comment added Sam Hopkins (I was going to make a comment about how this move is important in the strategy-stealing argument that Chomp is a 1st player win, but I see you mention that as motivation in the MSE question, so I'm just leaving this parenthetical instead...)
