I get the theory & I have seen it in action all too often. I havent read much on 'Implicit Collusion' but that doesnt seem too unreasonable either.
It definately applies to lower ($.02/$.04 through $2/$4(?)) limit games, but I am not sure it applies as much to tournies.
unless you're playing some wacky unlimited rebuys / winner takes all tournament. Or for free money online
What i've found is that position play, overtime, is a very strong defense.
If you're playing tight/aggressive, raising a premium hand in position is nearly a must.
raising non-premium sets is up to you, milage caries to future hands.
Against a school I play position fairly consistently - tight/aggressive - so if I come out with a raise, in position, it doesnt "shock" anyone into folding & the school calls.... just test the water.
if I hit a premium hand out of position - i check it or raise a BB - the school will do the betting.
OR - post checking, if one limps early, and others follow around - a check-raise (2-3xBB)works too. get in front of the hand, throw out some bait. give balance & thought to them coming back over the top... LOL
Most action against a school depends on prior history at that table. Guess I am saying it depends on the size of your stack/bankroll/game & opponent.
maybe i've been lucky for the past 95-years
