Is this gambling?

I've always thought that gambling refers to a game of chance; such games are haram in Islam, and rightly so.

But someone today told me that he thinks playing golf for money is also "gambling" and thus haram. For example, 4 people agree to play together, and to spice things up a bit, they all agree to put RM50 into a pool, winner take all. Surely, that's not gambling, is it? Its a game of skill, the RM50 is the "entry fee" and the RM200 that goes to the winner is the prize.

Playing games for money = gambling = haram? I think not.
