Sure! Here are some sample unit tests for the provided code:

```
import unittest
import socket
from unittest.mock import Mock, patch
from board_game_server import BoardGameServer

class TestBoardGameServer(unittest.TestCase):

    def setUp(self):
        self.bgs = BoardGameServer()

    def test_create_server(self):
        # Mock socket object
        mock_socket = Mock()
        mock_socket.accept.return_value = (Mock(), Mock())
        with patch('socket.socket', return_value=mock_socket) as mock_sock:
            self.bgs.create_server()

            # Verify socket was bound and listening
            mock_sock.assert_called_once_with(socket.AF_INET, socket.SOCK_STREAM)
            mock_sock.return_value.bind.assert_called_once_with((self.bgs.host, self.bgs.port))
            mock_sock.return_value.listen.assert_called_once()

            # Verify connection was accepted and message was sent
            mock_socket.accept.assert_called_once()
            mock_socket.accept.return_value[0].send.assert_called_once_with(b"Would you like to play a game?\n")

    def test_register_game(self):
        self.bgs.register_game('checkers')
        self.assertEqual(self.bgs.game_state['board_size'], 8)
        self.assertEqual(self.bgs.game_state['game'], 'checkers')

    def test_end_game(self):
        # Placeholder test
        self.assertIsNone(self.bgs.end_game())

    def test_place_piece(self):
        # Placeholder test
        self.assertIsNone(self.bgs.place_piece(1, 2))

    def test_remove_piece(self):
        # Placeholder test
        self.assertIsNone(self.bgs.remove_piece(3, 4))

if __name__ == '__main__':
    unittest.main()
```

These tests verify that the `create_server()` method binds and listens on a socket, accepts connections, and sends a message to the client. They also test that the `register_game()`, `end_game()`, `place_piece()`, and `remove_piece()` methods can be called without error.

Note that these tests only cover the basic functionality of the methods and do not test for specific edge cases or error handling. Additional tests may be necessary to ensure the robustness of the code.
