What are tai chi's high-percentage push hands techniques?

Question

In the context of tai chi push hands, what are the most commonly effective techniques? (Push hands in competition and in class both count.)

For analogy, in judo, it is well known and documented that the strongest players at the international level win most commonly with throws like osotogari, seoinage, and uchimata, whereas haraitsurikomiashi and udegatame, for instance, are seen much less often and mastered by fewer practitioners.

What are the high-percentage techniques of tai chi push hands, that nearly all players employ, or that many players employ to great effect?

Answer 1

Needle at Sea Bottom is a fave for fixed feet push hands. Personally, I dont like the move but have been on the receiving end enough to know its effective in competition.

You can see it in this video at about 33 seconds in. The initial body and hand positioning is reasonably close to tournament and you can see the hip turn whilst sliding the weight backwards and controlling the opponents arm to throw them to the side. With fixed feet push hands, all you need to do is uproot and this move is often used very quickly from the start of the point.

A counter to it is to relax the arm being pulled, initially going with the movement (in the example above the hips would be rotating around to the left) but then rotate the hips to the right, slapping with the pulled hand followed up by a push with the left hand. Or just relax right out of the initial hold and help your opponent continue his movement backwards.

He also used as the first move in this demonstration at 45 seconds.

Answer 2

From a translation of Li Yaxuan's 35 points of Push Hands:

The real Taijiquan skill is invisible. The application of Taijiquan is to be found in understanding of insubstantiality, formlessness, and mind alone. The taste and feel of real Taijiquan cannot be had from any application of visible technique or obvious force. That just drifts you farther and farther from the real art of Taijiquan.

Perhaps this means that Taijiquan does not attach itself to particular techniques. The most popular skill, then, would be no-mindedly leading the opponent to unbalance.
