Fabian is not so easy. Again my suspicion seems confirmed that not so much training issues but a health problem is a the root of complications. Alas - the decision stands. I will never again be afraid of his fast unexpected reaction and I will challenge him regardless. More than all the other horses he provokes me to be straight forward, thorough and with him. And - whatever we accomplish - it is more than enough in light of the information he provides and his rider's character schooling.
Today's mistake was on my part. Instead of establishing the shoulder-in, particularly to the left, and then phasing in the haunches-in I began to alternate the two right away. Somehow he didn't understand me and instead of changing the program and first do our ten minutes walk, reins hanging I insisted. Discouraged and annoyed he released the back. The remaining training time was occupied with reestablishing rapport and raising his back. Small victory, in the final walk, reins hanging he delightedly tasted his bit.
I add the following note: Fabian, when he comes in from the field, needs a warm-up (ca. 10 minutes walk reins ranging) before he releases the jaw and signals well-being. Any work with the bit amounts to nothing before that. Even vibrations. He is completely cold to the leg.
Once he is well he releases the jaw as he sees fit. I can not demand the release of the jaw and be certain he responds properly. Instead often he offers a lateral flexion and/or backs up. He willingly and promptly responds to upward actions of the rein and transfers his weight to the haunches. He responds to the leg. More so he offers motion and pizzaz.
