Start from doing forward ocho with Lady's RF fwd. (Sometimes from rock step. Lady's RF rock back, LF replace, then RF fwd)
Man does not lead the swivel when Lady is on her RF, instead he leads Lady to keep moving fwd with her LF and then turn her to her R.
After Lady steps her LF (smaller step, don't pull Man), Lady swivels on balls of the feet, Man lowers Lady into her L knee to sit into her hips, her R toe can come up. Lady overturns her hip/body/shoulder to R a bit (to wind up). Do not lean back and take arm with body. Instead, sit, hip overturn to R a bit, pitch fwd and leave arms with Man. Head looking forward (not away to R, not keep all the way to Man either, which will be too twisted.)
Then Lady step onto her RF (let body start rotating sooner to left, don't do Latin style on RF and then sharp turn. make movement smooth, wind up, recoil, untwist) Swivel into a cross (LF cross in front of RF)
Starting from position 3 of 8 Count Basic
Quick: Leader steps forward with LF using CBMP, small step, without fulling committing weight. There should be no lowering, should stay at same level. As follower starts to put her weight on RF, leader pulls back on right shoulder blade to give energy to bounce back (rebote). Follower's hip will go a little farther than her shoulders.
Quick: Leader returns full weight to RF
Slow: Leader takes small step back with LF in line with RF
Quick: Leader turns hips and frame right, takes small side step with RF (this does diagonally back right from perspective of original line). Step should be small to allow follower to step past. Provide tension in left hand at end of that Quick to snap the follower back for the rebote, or rebound. Follower's hips should go a little farther than her shoulders. Leader should not be lowering on this step, should stay flat
Slow: Leader brings RF to LF, collecting, squaring up frame to line, this will lead follower to cross LF in front or RF (cruce).
Can proceed from here with resolution (resolucionI).
