This really helps because you can just sit and wait until you get a top pocket pair ie JJ, QQ, KK, AA, and just go all-in with it, no one will notice that you are playing tight so I guarantee at least 5 out of ten times someone will call.
I dont know if i necessarily agree with your strategy and if this person is a beginner then I dont think this is the best thing to do. Granted, I am not an experienced NL player, but I did play a lot of NL tournies.

Basically, JJ and QQ (as are any pocket pair) are coin flips against any two overcards (AK, AQ, etc.) and theoretically the only people calling an all-in bet will have these quality hands. Granted, you can make your case for the fish calling all-in bets with anything but you say 5 out of 10 someone will call. So if you are all-in, then 5 out of 10 ten times you are called, and half of those times you will lose to the coinflip. This strategy has a possibility of increasing a bankroll quickly but sustaining this is impossible.

I believe a couple months ago someone started a topic on this same subject about going all-in with top quality hands and the majority of time someone will call with a less-quality hand. I encourage you to read that topic. Again, I am not that experience in NL, but I have tried your suggestion before, and at best I was break even.

Just my thoughts.
