This strategy was given by a man who now goes by the pen name of Roy Rounder, he finished in 30th place in Event 2 this year at the series
He has newsletter which he sends out from time to time to his mailing list (which somehow I got on although i dont know how... but im not complaining some of the things discussed are interesting)
He recommended that this strategy be used in low limit NL TOURNAMENTS (30+3 and lower) not cash games. And it was to be used until there were 4-5 players left.
It was based on the theory that in low limits players will call with too many hands, and your chances of doubling up is large enough. If I recall correct it was...
AA or KK: Go all in
AKs AKo 22-QQ limp or call a standard raise. If you flop a set move in. TPTK bet aggressively
Axs and suited connectors 78 and above: Limp only, if you hit your flush or straight move in. If you flo a draw call bets when pot odds are in your favor, otherwise fold.
Everything Else: Fold
Realistically this makes no sense -- any idiot who has seen u fold 200 hands and then suddenly move in isnt going to call you unless he is strong (granted sometimes not strong enough)
However maybe it operates under the assumption that folding often can most of the time get you close to the money in low limit SnGs bc of the loose aggressive and stupid play that often is around these games. In addition youd only need 1 double up or so to be in good shape. He advises once it gets down to 4-5 players this strategy has to be aborted.
Never tried it but hey maybe ill enter a 5 dollar SnG once im up and running again and see what happens -- i mean he wouldnt jus pull this out of his ass and print it would he?

lol
