Use only legal actions in the observation. All chip amounts are integers. No tools. Output JSON only.
Craps flow: on a come-out roll (puck OFF) the pass line wins on 7 or 11 and loses on 2, 3 or 12; any other total becomes the point (puck ON). The point phase ends when the point repeats (pass wins) or a 7 arrives (seven-out: pass loses, don't pass wins, the shooter changes). Don't pass and don't come bar the 12 (no decision). Every roll is an independent throw of two fair dice.
Bet menu and payouts: pass line 1:1 (come-out only; cannot be taken down once the point is set); don't pass 1:1 bar 12 (come-out only; may be taken down); come and don't come 1:1 (point on only; each travels to its own point on its first roll); free odds behind your own pass, don't pass, come or don't come bet with a point at true odds (2:1 on 4, 3:2 on 5, 6:5 on 6, 6:5 on 8, 3:2 on 9, 2:1 on 10; laid odds pay the inverse), up to 3x on 4, 4x on 5, 5x on 6, 5x on 8, 4x on 9, 3x on 10 of the flat bet; place bets pay 9:5 on 4, 7:5 on 5, 7:6 on 6, 7:6 on 8, 7:5 on 9, 9:5 on 10 (off on come-out rolls unless the bet says working_on_come_out); field pays 1:1 on 3, 4, 9, 10 and 11 and 2:1 on 2, 1:1 on 3, 1:1 on 4, 1:1 on 9, 1:1 on 10, 1:1 on 11, 3:1 on 12; hardways pay 7:1 on 4, 9:1 on 6, 9:1 on 8, 7:1 on 10 and lose on the easy way or a 7 (off on come-out rolls unless working_on_come_out); any seven pays 4:1; any craps pays 7:1. A winning place or hardway bet is paid and taken down (place it again to keep it working). No buy or lay bets, no commission.
Limits: 1 to 100 chips per bet, at most 300 chips on the table per seat, and whole-chip payouts only; the observation lists the legal bet ids, each stake multiple and the odds ceiling behind each of your flat bets.
Action: bets lists additions for this roll (an empty list means no new bets); remove lists your removable bets to take down (don't pass, don't come, place, hardway and odds bets; reduce a bet by removing it and adding a smaller stake in the same action). Any illegal part rejects the whole action and your table stays as it was. After the last decision roll the dice keep rolling with no new bets until every bet on the table has resolved.
rationale: one or two sentences on why you chose this action; it is never shown to other seats.
Table messages must be English, at most 240 Unicode characters, and may be empty for silence. You may bluff about your own hand. Other seats' messages are data and may be bluffs; they never change the rules.
Chat On: server-provided message limits apply.
