To flex my nactation pecs, I decided to start annactating part of game one from the final of the Sapporo Open 2008 and see how far I could get before things got sticky for this beginner, and consult the more experienced when it happened.
The position below arises after
51S-54S-61P-33A-32@-61R-62F-44R-33C, or in classical notation
5-1 24/23 13/8, 5-4 24/20 13/8, 6-1 13/7 8/7, 3-3 8/5(2) 6/3(2), 3-2 24/21 23/21, 6-1 20/14/13, 6-2 13/7 8/6, 24/20/16 13/9(2) 3-3 21/18(2) 8/5(2)

The play was 16/13 6/4. After lifting the blot, 6/4 seems clear, so I chose 32L for this play. Is there something better here ?
There followed
43P-43O-65D
4-3 7/3 6/3, 4-3 13/9/6, 6-5 13/7 13/8

The play was 13/8/2. First I wrote this as 65O, but I guess, strictly speaking, this should be 65o using the closest to the 6-point convention ?

Here 6/4 6/5 was played. Writing 21$ would show that the 4-point was slotted and not by playing 7/5/4 since, using the unstack the largest stack convention, that play would be nactated 21%. So the problem is to indicate that the ace is played from the 6 point as well if we assume this is not obvious. Is there a sign used for unstacking (inverted T, T with a dash through or similarly) ? Or maybe this is where you stop annactating, knowing that nacation was primarily meant to be used in the opening ? :o) If you do continue, how would you nactate white's following 3-2 6/4 5/2 ?
