What it is
Chub fishing with a float is about putting a bait where they live — under the far bush, in a rush hole, down the crease — and being ready for a fish that does not mess about. An Avon or a big stick, a bait they want, and a hooklength that can pull them out of the tree.
Travel light, look, first trot through a new hole is often the one. Then they know. Open season only.
