Roulette table

Maximize chance of a large payout to reach the 1500 target quickly, using the maximum allowed stake on the highest-payout bets.

Betting 22 on four straight numbers gives a net +704 if any hits, reaching the 1500 target, while allowing up to 9 attempts with current bankroll.

With only 11 spins left and needing a large bankroll increase, max straight-up bets offer the highest variance and best chance to hit the 1500 target quickly.

Bankroll 512, target 1500, 9 spins left. Maximum legal total stake is 200; betting on six straight-up numbers gives the highest one-spin success probability (6/38) because any hit yields at least 988 net profit and reaches the target.

With only 312 chips and 8 spins left, reaching 1500 requires a large payout. Betting the maximum on two straight-up numbers gives the best chance of a big jump; any single win would exceed the target.

With 112 chips and 7 spins left, I need a large jump. Betting 41 on two straight numbers gives a 2/38 chance to immediately reach 1506 chips if either hits, while leaving 30 chips if both miss.

With only 30 chips and six spins left, the only realistic path to 1500 is an all-in straight-up win followed by another large straight-up bet; splitting stakes lowers the maximum payout, so I maximize variance on one number.
