| Section 2: Tsukata Special |
To drop P at 2d right after its exchange is a clever move, aiming at,
of course, snatching P on 6d.
After the above: (from white)
R-8b; P-1e, Px1e: P*1d, P*2c; Rx6d
I can never forget the day I witnessed what was going to be called the
Tsukata Special. It was one of the Osho League games, played by Yasuaki
Tsukata and Makoto Nakahara, on August 22, 1986. I was right there next
to them, because I was a record keeper. When I saw Black's P*2d, the honest
reaction on my part was, "Tsukata-sensei doesn't know the joseki!?"
It is not even joseki, but joshiki (obvious reasoning) that snatching P
on 6d through P*2d, Px2d, Rx2d is impossible when S is at 3h, because White
then will respond as P-1d, thereby claiming Black's N by P*2h in exchange
for giving P on 6d. Therefore the Black Silver has to be at 3i.
Tsukata-sensei, however, looked brimming with confidence, making P-7f. White
then took a natural course, P-8f, Px8f, Rx8f, instead of S-6c, which would
have met Black's B-7g to refuse P exchange. It was not until I saw Tsukata-sensei's
P-1f that his intention dawned on me. For White's S-6c, he would attack
from the first file as P-1e, Px1e, P*1d. What the Tsukata Special aims at
are 1) snatching the P on 6d, and 2) an edge attack with P-1e.
Nakahara carefully pulled his R back to 8b, but Tsukata determinedly proceeded,
P-1e, Px1e, P*1d. At White's P*2c, Black made Rx6d.
Moves afterwards: (from white)
Rx8h+; Rx6b+, Gx6b; Sx8h
I was still dazed about those unusual opening moves, when suddenly White
made Rx8h (if (b)Sx8h, then the famous B*8f), giving me another surprise.
It was still before the lunch break. Tsukata-sensei undauntedly made Rx6b+
and then took R by Sx8h, which left me wondering which side was leading
the game.
