Choosing when to deploy your Fantasy Premier League chips can be a fine art.
For all the planning and strategising that can be involved, sometimes it can just be about pure gut feeling.
Having looked at his Gameweek 9 line-up, William Skaife felt compelled to wield his Bench Boost chip.
Avoiding all the big-name forwards, William had opted instead to pack his five-man defence and midfield with a cast of talent, creating a bit of a selection headache.
William could not bring himself to ignore raiding full-backs Danny Rose (£5.9m) of Tottenham Hotspur and Christian Fuchs (£5.4m) of Leicester City, while the opportunity to field Stoke City playmaker Xherdan Shaqiri (£6.3m) away to Hull City was also too strong to resist.
With these three players out of his starting XI, the Bench Boost chip was duly deployed - a decision that looks to have turned William's season on its head.
A clean sheet for Rose in the early kick-off at AFC Bournemouth got the ball rolling, while Fuchs maintained the momentum with a first Premier League goal.
When Shaqiri delivered a Gameweek-high 15-point return at the KCOM Stadium, the success of William's perfectly timed chip was confirmed.
The points that followed were to carry him to the top of the Gameweek 9 ranks.
Not done there, Sunday's events at Stamford Bridge took things to another level.
A third clean sheet in three ensured that Thibaut Courtois (£5.5m) took William's bench tally to 35 points.
Despite gaining only five points from his three forwards, William's defence and midfield bridged the gap.
Crucially, having seen Mane offer a modest return for his Triple Captain chip back in Gameweek 6, the Bench Boost had delivered and helped him to a peerless 115-point tally.
William was the manager of the week, climbing more than a 1.5million places be ranked 154,774 in the world.
