Self team: one model plays all three seats against the dealer.

Action timeline

Model's stated reason

At round 1 with no cards seen, a small bet minimizes variance while preserving bankroll for later rounds. The betting phase requires a legal multiple of five, and 10 is well within limits.

Model's stated reason

With no cards seen yet the count is neutral, so a small bet keeps variance low while we gather information from the shoe.

Model's stated reason

No cards have been seen yet, so a flat modest bet matches the team's stated plan and limits variance. Matching seat 2 keeps the table consistent while we gather information.

Stated reasons appear after the comparison block is revealed. They are model-submitted text, not verified reasoning.
