un pélam (ou bride je ne vois pas trop sur la photo) dans la bouche, pauvre cheval !! en plus, tenu trop court! il en ouvre la bouche tellement il a mal! (un cheval n'ouvre jamais la bouche quand on le monte en temps normal...) et le chanfrein est beaucoup trop serré!! O_o
Unfortunately, I do not know French, so I'll answer in English. This photo was taken during an amateur competition. Many riders did enormous errors, very painful for their horses. Unfortunately, the judges were not able to disqualify participants, because the competition was unofficial.
yes sorry I've writen in french... I said this: "a jaw Pelham (or flange, I do not see too much on the photo) in the mouth, poor horse! it is held too short! he opens his mouth so much it hurts! (a horse never opens his mouth when the overlaps normal ...) and the chamfer is too tight!"
Yes if it's an unoficial competion there is no way to disqualify the rider... (too bad!)
Escafan, this is a military competition(Path with things, which you must cut or prick sabre or lance). You can see traditional polish, military equipment. Pelham was always used. Army prepared rider to future war, and in war, uhlans must strongly lead(often one hand) the horse among shots and explosions. The ordinary mouthpiece wasn't suitable to cavalry regiment.
Actually, double bridles were traditionally used to fight from horse back so reins in one hand and weapon in another - as in the photo. And everything I can tell it's still a standard for the Polish cavalry so it may have nothing to do with the rider. The double bridle is very common in military and in dressage. Though it shouldn't be used be someone with heavy hands or inexperienced. My point though is, bridle does not make him a bad rider. Now the leg is a bit far back. But don't judge on the tack.
