Today's Brain Game consists of puzzles that I call heebies. You'll examine a set of clues that can be solved with only four letters; specifically, a two-letter sequence followed by the same two-letter sequence in reverse.

If the clue were "Ancient two-way radio?" the answer would be BC CB. For "A so-so match-ending punch?" we'd be looking for an OK KO. Got it? Good. Here we go:

1. Kisses and hugs, bovine?
2. An alien pass blocker?
3. 900 are hosting?
4. What keeps the Golden State cool?
5. A chick-doctor's funk?

Here are the ANSWERS.

THE ANSWERS:

1. XO OX
2. ET TE
3. CM MC
4. CA AC
5. OB BO
