Something went wrong when use move function from string UCI move

[sophiathedev]

hello, i've used surge source code for my chess engine, when i create uci for my program with position command

position startpos moves e2e4 e7e5 g1f3 b8c6
     A   B   C   D   E   F   G   H

After this, I got the Queen at H8 for no reasons. I think it is a small bug inside the play function when call it with string move.

...
else if (string_lower(token) == "startpos") {
  // append default fen string to position
  this->position = Position(DEFAULT_FEN);

  iss >> token;
  if (string_lower(token) == "moves") {
    std::string move_line;
    std::getline(iss, move_line);

    std::string move;
    for (char c : move_line) {
      if (c == ' ') {
        if (this->position.side_to_play == WHITE)
          this->position.play<WHITE>(Move(move));
        else if (this->position.side_to_play == BLACK)
          this->position.play<BLACK>(Move(move));
        move.clear();
      }
      else
        move += c;
    }
    if (!move.empty()) {
      if (this->position.side_to_play == WHITE)
        this->position.play<WHITE>(Move(move));
      else if (this->position.side_to_play == BLACK)
        this->position.play<BLACK>(Move(move));
    }
  }
  uci_output(position);
}
...

This is my source code for position startpos moves command.
Thanks for your help and sorry for my weird english !`
