In Response To: XG question: Double point at -2,-2 (Bob Koca)

That looks like a perfectly correct answer to me (what a surprise). The difference comes from stealing all of the opponent's cube power.

Is it correct to say that doubling is strictly right when the two following conditions apply, and strictly wrong when neither applies ?

1) One has at least one two-roll market loser sequence.

2) There is no immediate roll that loses the opponent's market (otherwise, doubling would throw away an opportunity to pass).
