Classic Opening Queen Trap
Solve if White did an in-between move without first doing the steps to prevent the queen trap:
Only Black's king should move, else Black's other pieces would fail to keep the White queen trapped.
To prevent the trap after Black plays Kh6, White should a) lift the d2 pawn to open its black-squared bishop, or b) play Nf3/Nh3 or c) back the queen (not the best idea because moving the queen a lot early in the game delays development) or d) take Black's f7 pawn (the worst option since Black's knight will just take it, but that still prevents the queen trap) .
However, many times, White fails to follow it up properly. Thus, Black still succeeds in capturing White's queen early in the game.
A common blunder is when White uses its dark-squared bishop to counterattack Black's queen.
