How to point out verbs from grammar expressions?

Sorry if the title is hard to understand. But a few weeks ago I learned something like 忙しくては、本が読める時間がない to exprss being so busy you have no time to read. Today, I encountered something like 金もうけにかけては、まさおは天才だ。I thought this was the same kind of idea but instead it has as for this, x kind of meaning.

I find I have a lot of trouble with this. Understanding between grammar points, or just a verb in the te form, and expressions. Is this just something you recognize over time? I've been studying Japanese since 2007 and I feel like this is something I can't recognize at first glance.
