Market Losers Deck 3

Take a look at these positions and consider whether you have enough market losers to offer the cube to your opponent.

The threshold for an initial double is a net of 9 market losers, provided you are doing alright on the rest of your rolls. Net market losers means Blue’s market losers minus White’s anti-market losers, the very bad sequences after which White is a clear favorite and may soon own a cube of his own. For redoubles the bar is higher, around 11 or 12 net, because by handing over the cube with a premature double you forfeit your own access to the cube. A premature double is a gift to your opponent, who would then have the ability to use the cube as a weapon against you.

Read the chips for clear market-losing rolls and anti-market replies; darker shades show stronger effects. Net estimates reflect the two-roll sequence—both Blue and White—not a sum of the chips.
