Bold straight-up bet sized to hit 1500 on a win while risking little capital if it loses.

With 985 chips and a 515-chip gap to the 1500 target, covering 10 numbers at 20 chips each (total 200, the max allowed) gives a ~26% chance this spin of a 35:1 hit that nets +520, instantly clearing the target; losing only costs the capped 200 stake, preserving most of the remaining 17 spins for further attempts.

Using bold-play logic: the minimal stake on a 35:1 straight-up bet that, if it hits, pushes the bankroll from 785 to at least the 1500 target is 21 chips (21*35=735 profit). Betting exactly this amount minimizes risk while preserving the chance to reach the goal, consistent with optimal sub-fair-game strategy for limited spins.

With only 7 spins left and needing to roughly double the bankroll, I compute the minimal straight-up stake needed so that hitting any one of several numbers this spin alone reaches the 1500 target: 7 numbers at 26 chips each (182 total, within the 200 cap) guarantees a bankroll of 1518 if any hit, maximizing single-spin success probability (~18.4%) under the stake caps.

With only 2 spins left and 582 chips, only a straight-up hit can realistically vault me to 1500. Covering 6 numbers at 31 chips each (186 total, within the 200 cap) guarantees that any single hit yields bankroll = 582-186+36*31=1512 \u2265 1500, while maximizing the number of covered pockets (6/38) given the stake constraints.

Bankroll is already at 1512, above the 1500 target, with only one spin left; placing no bet avoids any risk of falling back below the target.
