Betting 100 on a dozen maximizes the probability of reaching the 1500 target given the 19 remaining spins and the single-bet optimal policy.

Betting 22 on nine straight numbers gives a high chance to jump to 1494, from which reaching 1500 is very likely; this maximizes probability of hitting the target within remaining spins.

Betting 25 on four straight numbers gives a 4/38 chance to reach 1502 in one hit, and allows up to seven such attempts, maximizing the chance to reach 1500 within the remaining spins.

Need +898 chips with 13 spins left. Betting max total 200 on six straight numbers gives a ~40% chance to hit within the first three spins and immediately exceed the 1500 target; any hit pays enough to reach the goal.

With only 402 chips and 12 spins left, I need a big multiplier to reach 1500. Betting two straight-ups (35:1) gives the best shot at a large jump, and 17/20 have appeared recently.

Betting the minimum straight-up stake needed to reach the 1500 target on a win maximizes the number of attempts and thus the probability of success given the large required multiplier.

Need to reach 1500 from 164 in 10 spins; betting 40 on two straight numbers gives a 2/38 chance to jump to 1524, preserving 84 chips for another attempt if missed.

With only 84 chips and 9 spins left, the only realistic way to reach 1500 is a high-variance straight-up bet. Betting 42 on two numbers gives a 2/38 chance to hit 1512 immediately, maximizing success probability.
