Urgh, sickness...

It really was kind of a trick question. Most Taijutsu techniques can be bent to suit the situation. Take your technique there; it says abdomen, sure, but what's stopping you from hitting your opponent beneath the chin? In the groin? Nothing is. You're free to do so. The most important thing about the Tai techniques you want to use is that they
should cost no chakra point. If the technique costs no points to use you can use it and a chakra-requiring technique at the same time.
And therein lies the advantage in Taijutsu.

Now, this is the list of D-ranked Taijutsu techniques. They're not great, but they're certainly solid. Solid in the sense that they're versatile, if not exactly deadly. Still, in Taijutsu it's not important that you deliver a ton of 'damage.' Sure, you want to hurt your opponent, but the thing is; you'll do that no matter if your technique delivers 20 damage or 80. There will be a difference, sure, but to a certain degree the margins are negligible.
Now, these techniques are pretty straightforward. Read them and ask about them.
