I leave for Mid Ohio Dressage Classic in less than a week, and today Hani vidoed my ride. I had so many break- throughs!!     For right trot halfpass, do not put outside leg too far back ! This results in breaking to the canter! Keep leg at girth and move haunches.  Left trot halfpass  -- start in shoulder-fore, then keep shoulders to right , and add haunches.  For left canter halfpass , ride canter with very following hands . Gadget will bend around inside leg and flow sideways. If you hold too much in reins, the canter falls apart.  Turn on the haunches  -- soft hands , strongly hold haunches to inside , then ride shoulders around like cow pony , only half-halting between steps to keep rhythm.  Stay soft/following in the hands  to keep Gadget soft in the neck/back.
