Action timeline

Model's stated reason

Fresh 6-deck shoe has neutral count and negative house edge expectation, so minimum bet preserves bankroll until a favorable count appears.

Model's stated reason

Fresh shoe with true count 0 means we should start with minimum bets. Seat 1 is providing count information and a clear strategy (bet min until TC >= +2), which is sound bankroll management for a team with 3000 chips across 20 remaining rounds.

Model's stated reason

Hi-Lo from 11 seen cards is RC +2 (six lows vs four highs), true count about +0.3 with ~5.8 decks left, below the +2 ramp threshold, so minimum bet preserves bankroll.

Model's stated reason

Seat_1 reports RC +2 and TC ~+0.3, which is below the +2 true count threshold established for ramping bets. With the shoe still neutral and 19 rounds remaining, betting minimum 5 chips preserves bankroll while we wait for deeper penetration and a more favorable count to justify larger wagers.

Model's stated reason

The true count is far below a meaningful betting threshold, so the minimum wager preserves bankroll.

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