Reveal the staircase before another row covers it.
The deep right-hand columns contain the most hidden cards. A move that turns one of those cards face up often beats a shallow foundation play.

The staircase changes the first priority
The Milligan family guide explains row-deal timing. Harp opens with eight columns holding one through eight cards. Only the top of each column is face up, so moving a top card from a deep column can reveal a card unavailable in the ordinary one-card opening.
Before dealing the next row, compare an exposed foundation move with a tableau transfer that flips a hidden card. The transfer can create another move immediately; the next row will cover the current tops. The best choice depends on what the newly visible card enables.
Use unrestricted vacancies
Descending alternating-color sequences can move together. Any card or valid run may fill an empty column, unlike the King-only vacancies in Miss Milligan. If a short column is cleared, it can temporarily hold a blocker from a deeper staircase column. Make sure the parked run has another destination before filling the only vacancy.
Harp has no Waive reserve after the stock. The tableau and eight Ace-to-King suit foundations must provide the remaining routes.
