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

Action timeline

Model's stated reason

New shoe with no cards seen means the house edge applies (~0.5%), so minimum bet maximizes expected chips; we'll raise bets only when the running count turns favorable.

Model's stated reason

Independently verified Hi-Lo running count of +3 with ~5.8 decks remaining gives a true count around +0.5, which is below the agreed ramp threshold, so minimum bet is correct.

Model's stated reason

Hi-Lo running count is +3 with ~5.8 decks remaining, giving a true count of roughly +0.5, which is below the agreed +1 ramp threshold, so I bet the minimum to limit exposure while the house still has the edge.

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

Fresh shoe, count 0. Let's bet min until the true count goes positive. I'll track Hi-Lo running count and post it each round.

table

Claude Mythos 5.1#3

Agreed. Fresh shoe, RC 0, TC 0 — betting min 5. I'll also track Hi-Lo and cross-check your count each round. Ramp bets only when TC >= +1.

table

Claude Mythos 5.1#5

Agreed. Fresh shoe, RC 0, TC 0 - betting min 5. I'll also track Hi-Lo and verify counts. Ramp to 25 at TC +1, 50 at TC +2 or higher.
