I wish I could show you how in person. It's a lot easier when you see it done slowly.
Make the loop with your leader, run your braid up thru the loop from underneath, I wind 7 times down and then 7 times back up, pass your braid back down thru the loop., wet the lines and slowly pull tight.
IF you are going to have a failure, it will happen when you pull the lines tight. The knot will fail if you don't get the line passing back through the loop in the correct direction.
The good news is that the knot either fails completely right then or its good to go. You won't have a knot that looks good at first only to fail on you when you hook a fish.
I have NEVER had an alberto fail on a fish.; I've been using it for years at this point and have literally caught 1000's of fish using an Alberto knot. I do have an alberto fail when I am hung and put a dead pull on it trying to bend the hook out or pull loose from snag. A word of warning, if you are using nanofil and you try to use a leader than is heavier than the nanofil, it will break at the alberto knot when you pull against a snag every time. If the leader is weaker than the nanofil, many times the leader will fail and you may have enough leader remaining to avoid having to re-tie everything.
I start with about 6 foot or so of leader material, that way the leader knot is just above my reel after I tie my lure on.
i won't tie a new eager on until I get down to 18 inches of the original leader length.
