how to play potentially dominated hands?

Say you have KQ and flop comes Qh 6d 2s. How can you tell if your dominated facing aggression?

Depends on who is being aggressive and how that compares to their usual lines.

Hand ranges and player tendencies.

All hands except the absolute nuts are potentially dominated.

Lets say you hold AA and the flop is Qh 6d 2s you are potentially dominated.

Lets say you hold 66 and the flop is Qh 6d 2s you are potentially dominted.

I think Baluga Whale said that domination is a silly concept.

Lets take the 66 and the flop is Qh 6d 2s. You are potentially dominated. You will not win this situation 100% yet you know that you can bet for value and hence you bet.

If you know how to value bet correctly then you can never be "dominated".

Value betting correctly requires that you understand the villains ranges and tendencies.
