Aggressive only works if you use it as an overdrive gear for short spurts of activity. While any good poker player will pick up on your tendencies if you play either tight or loose without deviating from a single strategy, you're probably better off going with tight. Take Danneman, for instance. The man readily confesses to being only the 4th best player in his home game but has made a name for himself by playing consistently tight and conservative in high profile tournaments. Conversely, consider Mike "The Mouth". He is the type of donkey I have cursed time and time again after getting my perfectly played and perfectly superior cards sucked out on the river by some miracle "4 outer" after I have priced the caller out of every reveal on the board. Any success he has had is due to nothing but luck, which in case you haven't noticed has a lot to do with the outcome of any hand you're in, no matter your odds
pre-flop. 7,2 off-suit can certainly defy the odds and flop full house every now and then and tight play will not guard against this. Who actually pushes with K's or A's expecting someone to call with 7-2? However, in the long run, tight play will prevail and will be rewarded that much more when you decide to shift into your special "loose play overdrive gear". Loose play, in the long run, results in a "Matusow Blow Up". Seriously, that guy should go back to making coke deals so he can go back to prison, which is where he probably learned his donkey style of play by scamming smokes off of the inmates.
