raising this flop looks far more defensive than aggressive.
As a rule i dont dump my AA on this board versus a dcent player a lot, i probably would against a fish.
I think this is actually a bad flop to float because a good player double barrels paired flops a lot on the turn simply because a strong hand declares itself quickly and a mediocre hand like 55 on this board hatyes the turn pressure and is probably making a mistake calling anyway (opp could easily barrel a medium pp on this board on turn too)
I think raising the flop needs to balanced as a float and draw/made hand but i tend to call much more on the flop now because too many opps tip the strength of their hand on the flop with a c-bet size. Not many always hit the same amount
