Well it's often incorrect to just make the easier play. Poker is a game about making money. Every decision you make will have either a positive expected value (makes you money), a negative expected value (loses you money), or an expected value of 0 (you breakeven). Your job is to fine the play everytime you are faced with a decision that will yeild not only a +EV, but the highest +EV. That is to say, it's definitely correct to open shove allin with AA. That play is +EV. However, the EV of open shoving AA is going to be less than raising AA to a standard amount and playing postflop.

So if simply making the easier play is what you truly do, then please refrain from giving advice as if it's a golden rule. Give an opinion that can be corrected. Don't say "never raise Q9s", as this is obviously incorrect, as in many situations it's a +EV raise. Instead, say, "I wouldn't have raised Q9s there, and rarely do as it's a tough hand for me to play". Even though this might be incorrect still as you could still be missing out on +EV plays, it comes across more like it's just a helpful opinion and should be interpreted as such, instead of it's advice from the poker God HIMSELF making an all-knowing post about how you should NEVER raise Q9s.
