therein lies the rub

There's the difficulty

Therein lies the rub identifies the core difficulty or obstacle in a situation: The plan sounds perfect, but therein lies the rub—we have no funding.

The phrase comes from Shakespeare's Hamlet, where "rub" meant an impediment in the game of bowls.

It typically follows an explanation of something that seems straightforward, introducing the complication that makes it not so simple.
