When to use it

Sets a single minimum condition: if just this one thing is true, the result will follow, and nothing else matters. 薬くすりを飲のみさえすれば治なおる means "if you just take the medicine, you will get better". It can describe a real situation (as long as) or a wish (if only), often with いい: 晴はれさえすればいい.

Nuance

Neutral, used in speech and writing. It can sound hopeful, reassuring or, with past forms, regretful: あの時とき連絡れんらくさえしていれば (if only I had contacted them then). The verb pattern changes: 飲のみさえすれば, not 飲のむさえば.

Compare

さえ alone means "even" and marks something surprising: 子こどもでさえ知しっている (even children know it). すら is a more written version of that "even". さえ～ば is a condition: 名前なまえさえ書かけば合格ごうかくだ (just write your name and you pass).

Tip: With verbs, use the ます-stem + さえすれば. With nouns, attach さえ and put the ば on the predicate.
