How mach should I raise on preflop? Should I use the same bet size or different?

Every day I play texas holdem I think about these questions. I usually bet 4BB both in cash games and tourneys. And the main reasons are: you never can be sure that hand I have. If I have AA I bet 4BB or if I have JJ I bet 4BB too.

What’s about tourney?

I think you should vary bet size. Some times call with AA or bet 2BB with KK. But not in SNGs! Slow play is the direct way to sng bankrupt.

If you play SNG poker tourneys, you should raise 4BB or go all-in. Even I don’t think that you should call any cards.
