Action timeline
Model's stated reason
Round 1 with full bankroll of 3,000 chips and no information yet. A moderate bet of 25 chips balances risk and expected value, allowing us to grow the bankroll through favorable plays while preserving capital for future rounds where we may have better information.
Model's stated reason
Round 1 of 21 with fresh shoe and 3000-chip bankroll. Starting with a moderate bet (25 chips, mid-range) allows us to gather information about deck composition and adjust sizing upward when we detect favorable conditions. This balances early-round risk management with position to capitalize on good situations as the shoe develops.
Model's stated reason
With a pair of 2s against dealer's 7, splitting is the mathematically optimal play. This allows two hands to potentially reach 12+ with the next card, with better expected value than hitting (which keeps a stiff 4). Dealer's 7 is moderately strong, making the aggressive split play justified to maximize our two-hand equity.
Model's stated reason
With 12 vs dealer 7, hitting is standard—the dealer shows strength and my hard 12 must improve. Doubling risks busting; standing loses to dealer's likely 17-21.
Model's stated reason
With 16 vs dealer 7, hitting is correct basic strategy. The dealer's upcard is strong (7 busts ~26% of the time), but my 16 busts ~42% on any hit. However, standing on 16 vs 7 loses more often than hitting (I win ~25% standing vs ~39% hitting after factoring dealer bust rate). The split hands are still incomplete—must continue.
