As Karaulish came forward starting to cover the ~7-9ft between them Olga did three things, the movements melting into each other as she waited for an opening and then took the opportunity. On his second pivoting step into the downward slash Olga would once more hop backwards onto her right foot and then swing her left leg back around behind to support her weight as she leaned back onto it, further distancing her upper body from the downswing just in case her opponent guessed she'd back up again and surged forward even further during his initial attempt to slice her from shoulder to chest.

The moment Olga landed on her back foot and Karaulish was just past the mid-point of his first downswing the orc's left arm swung up, letting go of the large wolf pelt she'd picked up not a second or two ago. It wasn't exactly made to act like a net and was considerably heavier than a normal coat of its size, but even still, with a little bit of a rotation during the throw and Olga's immense natural strength it wasn't a hard task to have the pelt sail right at Karaulish like a duellist's cloak, the idea to simply cover his vision or at least force him to step out of the way for the briefest of moments - all the time Olga needed.

If Karaulish was either hit and covered by the pelt or took the time to step out of the way as it flew through the air at him Olga would make one final movement in this small chain of events: After the pelt had been thrown and her balance was improved a little by her left leg swinging back to support her weight Olga's right hand shot forward, letting go of the spear she'd taken from Karaulish. It was hardly aerodynamic but given it only had to cover ~5-6ft to reach him from where she was now there was no need to put much thought into aiming. With a grunt of effort from the greenskin the old fighter's own spear would whistle through the air threatening to pierce straight through his stomach just under the solar plexus, barely over a second after the pelt had been thrown. 

As Olga had waited for Karaulish to approach as he went into his pivoting steps and then jumped back once more during his actual attack she'd be roughly 6ft away as each object is thrown, the first being thrown exactly as he is half done swinging downward, the latter 1.5 seconds after that.
