AXs is not a group 1 hand, you don't want to be calling raises with it, the flush just doesn't happen that often and flopping a 4 flush can be very expensive if that last card doesn't come.

Hand groupings are not the be all and end all in SNG's, when i first startd i read a lot of ring game strategy and then used it in SNG's (as i hadn't fully appreciated the difference) where it wasn't massively helpful, it's all about the where you are in the blind structure that determines which hands to play.

Bluffing is hard to get right, especially at low limits, but satisfying when it works, it's also vital for MTT's.

That's all that comes to mind right now, and good post JM, not Fyr as Rip said.
