Discover Judo

Hello,

Today I would like to talk about my sport: judo. It is a martial art, fight sport. This sport was founded by Jigoro Kano in 1882, is a blend of several fighting sport, but it is primarily a flexible sport. It is practiced in a dojo (the room), on a tatami (mat). The judoka fights bare feet and judogi (holding). The fighter wins the fight by dropping his opponent on his back, with more or less power. He can also win the fight by making a bid. The ranks of judo range are from white belt to red belt (very limited person). That is quickly what you need to know about judo.

Can you explain "make a bid" to me? I don't understand that.
