Stepping up into a quadruple shot can be the right idea if it is a
distraction play. But stepping up to the 5pt isn't a distraction play
because that's the point O wants to make.

In the variant, I have changed the roll to 52.

1. Rollout¹ Bar/24 6/2* eq:+0.035
Player: 51.07% (G:13.29% B:0.52%)
Opponent: 48.93% (G:13.06% B:0.47%)
Confidence: ±0.016 (+0.019..+0.051) - [100.0%]

2. Rollout¹ Bar/20 eq:-0.069 (-0.104)
Player: 48.57% (G:11.99% B:0.47%)
Opponent: 51.43% (G:14.62% B:0.42%)
Confidence: ±0.016 (-0.085..-0.053) - [0.0%]

3. Rollout¹ Bar/24 7/3 eq:-0.075 (-0.110)
Player: 48.60% (G:11.84% B:0.47%)
