RIO Checkmate 4″ Fly
The RIO Checkmate is a 4″ long fly designed specifically for Kings and Chinooks. It sinks well, offers excellent movement, and triggers strong, positive strikes from fish.
The available colors are tailored to match fish behavior in different river sections. Chartreuse is ideal when near the saltwater entry and targeting fresh fish, while other colors perform better when fishing upstream or after fish have been in the water longer.
Steelhead and Silver trout are known to respond strongly to this pattern. The fly features a #1 Stinger hook and RIO’s 44lb SlickShooter line for reliable strength when hooked.

Fished in a coldwater stretch near the river mouth and the chartreuse version worked perfectly. Fish took it immediately and made strong runs. The sink rate was natural and the hook held firm during the fight.

Used the olive shade in the upper river section. Caught a king salmon that had been holding for hours. The movement matched the current and the fish reacted positively. Solid performance in varied conditions.
Max Dowd –
Good sink and decent action. A bit stiff in fast currents, but still effective. Would recommend for upstream fishing with larger trout species.
Olivia Davidson –
The 44lb line and stinger hook combination made a big difference when fighting a large Chinook. The fly stayed on the hook and didn’t break during the run.
