Effective pipcount and type of position
|
You can't assume that positions with the same epc are equivalent.
Suppose a player with an epc of 50.0 is on roll against a player with an
epc of 57.0.
- If both sides are very efficient, then this is a money pass, perhaps
1.100, as this is about a pip shy of a take. (46 vs. 52 nominal pips can
be a borderline take, but that would be 53 vs 59 effective pips.)
- If the player on roll has a pure 7-roll position, this is a much larger
pass (1.250+), as you can only take while behind about 4.5 pips. Rolls
minus 3 = 4, the maximum effective pip deficit at which you can take
according to Trice.
- If this is a 7-roll versus 8-roll position then the roller wins 89.5% of
the time, and this is a 1.534 pass.
The way I usually express this is that the maximum deficit at which you
can still take depends on the type of the position. In a pips-versus-pips
position, you may be able to take while an extra pip behind compared to a
pips-versus-rolls position. In a rolls-versus-rolls position, or one in
which both sides are very inefficient with few repeated misses, the take
point may be moved up 2 or more pips.
