I find that large pairs are better being played aggressive, but more money in the slow leak. Is there a better feeling then calling before the blind and hitting trips on the flop - now you can make some money
Your already doing that with your 22's - 99's...

The best feeling is having that 44 with an AJ4 rainbow flop. Watching that AK and AJ raise and reraise thinking they have the best hand.

I just dont see why you would want to play your AA's - QQ's this way when a 22 - 99 would work much better.

What it boils down to is this: AAA makes LESS than 222, and AA makes MORE than 22. Thats why you play pairs like you do.

Use a standard raise to hide your hands power, not skipping a needed raise.
