You can IB > Reversal in between 5B >2B, 2B > 6B, and 5B/2B > 5C.
Jumping out is kind of iffy, but you can at certain points.
Also, IB 6D, and you get free punish most of the time, since if you were blocking, vivace A is most likely coming to close the gap. That's free CH for you. Watch out, because if it's not Vivace A, it's probably cross up time soon. (Which you can also IB and punish.)
