Can't run bot with default parameters

Hello,

I tried to run bot via instruction in readme:

  1. cargo build --release
  2. cargo run --release -s NegaScout -t 8 -g 1000
    I've got this error:

error: The argument '--moves-order <moves-order>' cannot be used with one or more of the other specified arguments

I tried to use all combinations of Solver [UCT, NegaScout] Moves-Order [None, Random, TrajectoriesCount] parameters, but still get this error can you help me?

Thank you!

The `find_best_move` test sometimes fails.

Repro steps:

  1. cargo test find_best_move
  2. Repeat 10 times
  3. 30% of the time it will fail at src/minimax_test.rs:26:2 (depth = 7), usually finding Some(37) (6, 2) or Some(26) (5, 1) instead of the expected Some(36) (5, 2).

Estimation for move (6, 3) is 0, alpha is -1, beta is 0.
Estimation for move (2, 4) is -1, alpha is -1, beta is 0.
Best move is (6, 3).
Estimation is 0.
Estimation is greater than enemy estimation. So the best move is Some((5, 1)), estimation is 1.
