Nice, So for the best for me is more complete early development (vs partial development partial attack that turns into less development in the end). And getting easier at seeing traps coming your way
Best thing about 4 player chess for me

I think 4-player chess is great for board vision. Even though I rarely blunder in "regular" chess, I have found myself hanging pieces quite a few times, especially with the time pressure.
The best thing 4 player chess has done is made me much more defensive minded. Now finding I am much more aware of opponent plans and ensuring that I cover for them.
