Decisions, Decisions

Given that we can compute r^p(d) for any combination of player sum p and dealer sum d, we'd like to create a ``stopping'' strategy for the player.

For example, let's suppose the dealer is showing a 10 and we have:

• r²¹(10) = +1.0
• r²⁰(10) = +0.9
• r¹⁹(10) = +0.7
• r¹⁸(10) = +0.3
• r¹⁷(10) = +0.0
• r¹⁶(10) = -0.1
• r¹⁵(10) = -0.2
• r¹⁴(10) = -0.3

The player has a 14 (no usable ace). What's the right thing to do?
