The idea of bull dog chess is just to make a variation of normal chess. It also makes the normal opening books less useful, and end-game theory and databases may need to be reconsidered before arriving at conclusions for a game (best move, win, draw, lose, etc). Also, cheating may be more difficult because there are few or no engines for this type of variant.
Some proposed or active chess variants have new powerful and creative pieces, such as archbishops, teleporters, death knights, robots, morphers, walls, and siege towers. I like those ideas, but they can be very powerful pieces, and may require much larger boards. That amount of thinking power is too much for me (but I love the idea and may try it sometime). Bull dog chess just has two new modest pieces, and is on an 8x10 board.
