QQ All-in pre-flop Was this a mistake?

On review, I realized that if I had just called the 4Bet pre, I might have been able to take it down on the flop.

Sure why not, you could always call low pockets to 3bet only if you hit set, right?
Stacking there is better - he should have some 4bet folds and you are OOP so by shoving you deny a lot of equity.

What you should work on ASAP are your sizings.

Hero raises to €0.14,

You are out of position, you should raise to at least 0.2€

Hero raises to €1.02,

This is terrible. Rule is simple - if your raise is more than 30% of your stack then you should just shove. Why? Its simple - because you have too good odds when opponent shoves to consider folding.

This is good advice.

I don't know if I would just 4bet call OOP. If you raise the flop bigger, the 3bet will probably be bigger and your almost committed to the pot. Besides that it might be a blind battle, so I usually consider these things as coolers when I run into better hands.
