16 vs 10, BJ Bluebook
In Blackjack Bluebook, Renzey says to stand with a 16 vs 10 if your hand consists of any 4s or 5s. Now I understand the reasoning behind this, but was wondering if you also stand if you notice any OTHER person's cards that has any 4s or 5s. Say you have a 10 and a 6, but notice that third base has a 15 consisting of a 4, 5 and 6; should we still hit or should we stand?
