For 2nd and 3rd combos, do not move forward before attacking. When you finish the previous combo, you are too far away to land an attack and so will get blocked 100% of the time. This is intended, as a post-parry attack deals more damage. If you walk forward and don't get blocked, you may need an extra combo to finish the fight.
For dad fight 2, for some categories you may have to be careful not to spam the attack input between combos (else the game will simply ignore your input). This depends on what levels you've healed up to that point. If affected, you have to wait until the previous combo fully finishes (Prince's feet stop moving) and then time your next attack, as spamming it will not work. See example here - this is with the hard strat but the same bit between combos applies: wait for the Prince's feet to stop moving before proceeding with your next combo.
Not recommended for beginners. Can take hours to learn for 4 seconds of average timesave.
Read the info on the easy strat first as it applies here too.

since the parry does extra damage so you can remove one attack from the final combo
