Rapid developing play. Go books often talk about 'pace', in relation to players who get quickly around the board.
It may seem obvious as a plan to do this, based only on a little experience of the game. Orthodox play at pro level developed in Japan in the Edo period along lines that made it less frantic, and more in touch with honte. In fact honte became more-or-less synonymous with 'professional move'. The value of honte may only become apparent in the endgame.
Therefore pacy play can't simply be greedy go, to be good. One gets the impression that those who have played rapidly-developing go and also been top players are important figures in extending the range of strategy.
DJ: I thought that the concept of "pace" in a game was connected to the ability to set the rhythm, the flow, the tempo of the game.
In other words, you play a move that induces an answer that in turn induces the move you wanted to play in the first place. But then I regard it also as the ability to keep the initiative on the whole, and this is closer to Charles's explanation above.
Anyway, this is the meaning I was referring to in my page A Zen Way To Joseki.
