Life In 19x19 :: White tengen - a reasonable move?

100%?

People need to shape up ... something like 60% would be great already, but 100%? Seriously, it's not the perfect move. Especially in a competitive setting people should be ready to accept whatever curveballs you throw them.

Oh, low sample size, huh?

May I ask why you want to know,
and whether you have your own guesses one way or another ?

I have a 100% winning score with a white tengen in tournaments...

Cheers,
Vesa

It is not worse than passing.

If you played on the central point as white for your first move, would that be giving your opponent an instant advantage

It's an interesting way to play. White has 1 corner to 3, but he seizes the initiative to approach first. He can also tenuki his approaches more easily, since there's support above, and so get stones into a couple of blacks corners. However, white tengen for the first move feels premature to me. Unless you're worried about black taking it, it seems every so slightly better to wait until your 2nd (or even 3rd, making an approach to a black corner for move 2) move. Make black choose his arrangement of corner stones before knowing that white is going to take tengen. I doubt it matters in practice, but that just seems more 'correct style' to me.

Black tengen however could be a good move.

If we assume that komi of 6.5-7.5 is reasonable, then the value of the first couple moves in the opening is about 13-15 points. If passing loses you 13-15 points, then realistically the worst case for tengen is going to be about half that (losing you 6.5 - 7.5 points). That means that if you are playing tengen as your first move as white, you shouldn't worry any more about it than you would making a mistake in early endgame (and that is if you are an extreme pessimist, it's entirely possible that it is costing you much less than that, if anything at all). For me personally, I would spend more time worrying about correctly timing my first line hanes in endgame (which are often double sente!) than I would about the fact that I played tengen in the opening.
