Trice's rankings

From:   Marty Storer

Subject:   Opening roll ranking: Walter Trice

Here's Walter Trice's opening-roll ranking, assuming doubles get
played before opponent makes a move.  Walter's comments included.

For those who don't know, Walter is a very strong player, rated
very high on the Goulding rating list.  I think he's just about
a full-time student of the game.  He wrote the excellent
Bearoff Quizmaster software.

66 24/18(2), 13/7(2)
11 8/7(2), 6/5(2)
44 24/20(2), 13/9(2)
33 24/21(2), 13/10(2) or 8/5(2), 6/3(2)
   comment:  after most openers by opponent, 24/21(2), 13/10(2)
             is best, certainly better than 24/21(2), 8/5(2).

22 6/4(2), 24/20  comment:  this wouldn't be best against most
                  openers by opponent, but here it looks right.
                  24/22(2) instead of 24/20 is better than it
                  looks, because it makes it harder for opponent
                  to play 5's and 3's; note in particular 55!
                  13/11(2) also good.  13/11, 24/22 too loose.

31 8/5, 6/5
42 8/4, 6/4
61 13/7, 8/7
53 8/3, 6/3
65 24/13     comment:  53 and 65 about equal; not sure which is better.

55 13/3(2)
64 24/18, 13/9
63 24/18, 13/10
62 24/18, 13/11
43 13/9, 24/21
   comment:  really think this is best because of the builder position:
             builder on the 9 point gives better building potential.

32 13/10, 13/11
   comment:  13/10, 6/4 is strong against weaker players, against whom
             it's very good to make unstacking plays.  But 13/10, 13/11
             often leads to complex prime-vs.-prime positions which
             weaker players will often mishandle; 13/10, 13/11 is
             probably the best theoretical play, but who really knows?

41 13/9, 6/5
   comment:  the primary motivation of this slot (and other opening
             slots with 1's) is to unstack.  With this move in particular,
             slotting just as a tactic to try to make the 5 point makes
             little sense.  But it leads to very complex games, especially
             as compared to 13/9, 24/23.  Who knows what's theoretically
             best?  13/9, 6/5 is the practical choice for a strong player
             in money games and even-ish match situations (splitting
             is often right when ahead).

54 13/8, 24/20
   comment:  I sometimes play 13/8, 13/9; don't think there's much

51 13/8, 6/5
   comment:  I sometimes play 24/18, but this is better.

52 13/8, 13/11 or 13/8, 6/4.
   comment:  13/8, 6/4 has strong unstacking appeal.  Don't know which
             is better.

21 13/11, 6/5.
