When you can't use it
- When the condition is an action verb the speaker controls, ば resists a command/wish in the main clause: ×日本へ行けば写真を撮りたい sounds off — use たら instead (行ったら撮りたい). ば prefers state conditions (あれば, 安ければ).
Easily confused with
〜と ば is hypothetical ('if it were cheap'); と is an automatic, every-time result ('press it and it opens'). と can't be hypothetical, ば isn't automatic. たら ば leans general/hypothetical and prefers state conditions; たら is concrete and sequential and freely allows requests. When in doubt in speech, たら is the safer default. なら ば states a plain hypothetical; なら picks up a premise just raised ('if that's so') and can place its clause after the result in time.

Notes
- ば is the conditional of proverbs and general truths: 塵も積もれば山となる ('even dust, if it piles up, becomes a mountain').
