I think this is probably the hardest to deal with...overly aggressive players..however, time and again I have found that Patience and paying attention usually pay off...as an example I was just in a 45 player SitNGo on poker stars, I lost a few bad hands early to these overly aggressive (all inners) so I adapted my tactics and played very tight..I got a little luck too,,but I didn't open bet when I was in front of one of the crazies, unless I had a monster..as luck would have it I survived down to the final table and then yes I won the tourney knocking out one crazy after another....of course there was luck involved but I just kept catching at the right moment..basically I just let the crazies kill each other off. and then took control
