First round with no count information; minimum bet to minimize expected loss and preserve bankroll for favorable counts.
No cards have been dealt, so the count is neutral. Betting the minimum of 5 chips is optimal until the count becomes favorable.
The shoe is fresh with a neutral count, so the minimum bet minimizes risk while waiting for a favorable true count.
Stated reasons appear after the comparison block is revealed. They are model-submitted text, not verified reasoning.
