I only roll with singles for bench and deadlift. I need to start doing it with squats pretty soon though.
It's a pretty cut and dry max effort template.
Start with a good warm up. Pick your next weight around 40-50% and do a couple reps. Increase the weight, do a couple more reps, and then start with your singles. Work all the way up until your 1RM for that day.
Then, drop the weight to about 75% and rep it out as many times as you can (I don't usually do this for deads though).
Now, being that your still a beginner, I don't think that's most effective for you. I think you still need more volume so I would keep you in the 3 to 5 rep range for multiple work sets, but with a reset between each rep.
That's my two cents.
There is nothing "smart" about a 3rd attempt deadlift.
