Comment on AGGRO pf-style!

Please add your wisdom to the following thoughts on preflop play!

Basic idea - often take the lead or be out. Only play marginal hands in position.

1.
Never open-limp. Always come in for a raise.

(perhaps you all do this?)

2.
"Never" cold call a raise as first caller. Either Reraise OR fold. Exception - weakling with big stack raised, then a call with a marginal hand may be OK.

3.
Only limp in with selected hands (low pairs; Axs; sooted connectors) when in LP and there are 2+ limpers in before you; possibly also in MP when table is passive behind you.

Blinds - conservative and tight.

Please comment on the merits and drawbacks of this approach!

Thanx,
