playing loose can be profitable, but the safest strategy is a solid TAG style.
I don't usually do much with suited connectors and I will get more aggressive in position at times, but I'm basically looking to hit a big hand and get paid off for it and I'm willing to patiently wait on those to happen. I don't follow a strict hand guide but I generally try to play any pair including deuces (calling and/or opening with a raise with them) and looking to set or win through aggression. AK/AQ/etc. I may vary my aggression a bit depending on the table (I will get more aggressive if the table is full of nits...as often is the case and I will tighten up against maniac calling stations somewhat..no point in
bluffing someone who will call you down with jack high as easily as he would with a boat).
GAP concept also comes into play for sure... If i'm in middle or late position I might open with a raise with A9/AT/AJ/KQ/KJ type hands but I won't from early position and I won't play alot of the hands I might open the action with if someone else has already opened the action.
One of the best pieces of advice I think I can give is if you have a small hand you should play a small pot, if you have a big hand try to play a big pot. Sounds so obvious but most people don't really get it. Here is part of it...top pair, TPTK, even sometimes an overpair are still just *one* pair. Try not to go broke on them and try to bust anyone who is willing to when you get better.
A more LAG style is very difficult to do profitably at micro limits and will definitely be far more swingy.
