No-Hole-Card with OBO Protection

6D · S17 · DAS · OBO · 3:2

A no-hole-card profile where only the original wager is lost if the dealer later reveals blackjack. OBO protection preserves U.S.-peek-style double and split strategy.

Reference

Reference only — verification pending

No hole card until after you act; only the original wager is exposed to a dealer blackjack (OBO).

Reference only

The chart for these rules

Strategy verification pending

This preset cannot be selected for graded practice yet. Sharper Edge never guesses: every practice profile is graded against a published, independently cross-checked strategy chart, and this combination of rules has not been verified against two independent references. Until it is, the profile is reference-only — use it to compare tables, not to train. OBO and American peek are strategically equivalent for added split and double wagers, but the round flow differs.
