Folding Top Pair (tourney)

LAYDOWN

When Player 9 raised on the flop with over 1/3 of his chips, I felt he was committing himself to go all the way. I thought a call would be a weak play on my part, and raising was very questionable especially with another player in the hand. I suspected this hand would be a major confrontation so I folded knowing that I hadn't invested that much anyway.
