"One step behind" or "one move too late"


I heard this phrase that sounds like 「いいえ、 **一手のさで** 、私どもの勝ちです。」, which in the
context should mean one is one step behind, or one move too late, or being
overtaken by someone else in doing something. But I cannot catch what the last
part (after の）means. I don't actually know for sure if the first two is 一手,
but it looks to me the only possible fit. After の it might have been さて
instead of さで, but I cannot search online with just this.

I am fairly sure this is not slang/colloquial, so I doubt it's a modification
that does not appear in dictionary. What is the exact phrase, and if I heard
wrongly what is the closest to this?




> 「一手{いって}の **さ** で、私どもの勝{か}ちです。」

It seems your listening comprehension is good. You caught every single word at
least.

It is just that the 「さ」 is 「差{さ}」 meaning "difference".

The word 「さて」 is not used here.

「一手の差で」, therefore, means "by the difference of a single move".

> "It is our victory by the difference of a single move."

No part of the sentence is indeed either colloquial or slangy.
