Betting 15 chips on a straight-up number achieves the 1,500 chip target on any single hit while maximizing overall success probability across 20 spins.

Under bold play for subfair games, betting the exact amount on a straight-up number needed to reach the 1,500 target minimizes house edge exposure and preserves bankroll if it misses.

Needing 530 chips to reach the 1,500 target, a straight-up bet of 16 chips pays 35:1 (+560 chips) to hit the goal immediately, maximizing overall reaching probability over the remaining spins.

With 17 spins remaining and needing 546 chips to reach 1,500, a straight-up bet of 16 chips pays 560 on a win, hitting the target immediately with maximal probability under the submartingale drift.

With a deficit of 562 chips to reach the 1,500 target, a single straight-up bet of 17 chips pays 35:1 for a 595 gain, reaching the goal on a hit. Bold play on the highest variance bet maximizes the probability of success in subfair conditions.

Covering 6 numbers with 22 chips each risks 132 chips to yield a net profit of 660 on a hit, reaching the 1,500 target immediately while maximizing overall hit probability across available attempts.

With 14 spins remaining and needing 711 chips to reach the 1,500 target, a straight-up bet of 21 chips achieves the goal in a single hit while preserving maximum bankroll for subsequent attempts.

Betting 23 chips across three straight-up numbers maximizes our probability of hitting 1,500 bankroll in a single win while giving us 11 attempts over the remaining 13 spins.

With a bankroll of 699 and a target of 1,500, a minimum stake of 23 on a straight-up bet yields 805 profit to reach 1,504 on a win while conserving bankroll for future spins.

To reach the 1,500 target from 676 chips, a single win on any of five straight-up bets at 27 chips each nets 837 chips, hitting 1,513 bankroll.

Covering 6 straight-up numbers at 32 chips each risks 192 total, yielding a net profit of 960 on a hit which immediately hits the 1,500 target bankroll.

With a current bankroll of 349 and 9 spins remaining, a single straight-up bet of 33 chips yields a net payout of 1,155 on a hit, reaching the 1,500 target while preserving enough bankroll for up to 9 consecutive attempts.

Betting 37 chips on each of four straight-up numbers reaches the 1,500 target immediately upon hitting (yielding exactly 1,500 bankroll) while conserving enough bankroll for another four-number attempt if this spin misses.

With 168 chips and a target of 1,500, placing 42 chips on four straight-up numbers maximizes the single-spin probability (4/38, or ~10.53%) of reaching 1,512 chips in one hit.
