My favourite kick has to be, without a doubt, mawashigeri. However, in actual combat, when this kick or any kick is executed to the jodan area it leaves the attacker suceptible to counter attack unless he is quick and precise enough to hit the target and return to a ready position in time for the counter.

I belive the most effective kicks in combat are those below the belt, in particular to the instep, the kneecap, the shin and, to a certain extent, the groin area

. Firstly, they act below eye level of the assailant, so they are difficult to see. Secondly, they can cause maximal damage when executed to these areas and the reach of the leg allows you to attack when you are a considerable distance from the opponent.
My favourite hand technique is haito (ridge hand). It is unconventional and sneaky and can cause a lot of damage when executed properly. It's downside is that it can be easily blocked if you are not fighting in close quarters with the opponent

What are your favourite techniques and why?
