That seems a bit too loose to me. When white replies with :w74:, 'a' and 'b' are both serious weaknesses, and any white move 'c' is a geta-breaker to make 'b' come alive.

The net effect is that :b73: is then gote for black, and white gets the first big move on the upper side:

Whereas with the more solid :b73:, black leaves the bottom with sente and he gets to be the first to play on the upper side:

No worries Chew, I had been thinking the same thing, not just on this move.

wow... my English fails. But I can't think of a way to word that better.

Now that B has provoked W to defend at G2, the aji of a cut at "a" is serious. For example, W can probably play the following in sente. If B does not defend, the W cut captures a stone and takes control of the center. So for W to atari the other way (W1 at H6) is aji-keshi and loses sente. I think W will play something like this, then take the large point "b" on top.

I disagree with virtually all of the analysis posted so far about the latest move. Black's play at F18 is making a fist. I predict that white will do somehing to strengthen his center group.

The sequence above is gote AND aji-keshi. If white is willing to play gote, M3 is gote and is way bigger.

Both the 1-2 exchange and the 3-4 exchange are aji-keshi. And if white does tenuki next, he plays up top around M3, which is way more urgent than 'b'.
