Tight is right!
With micro stakes MTT's you have to be very patient as there are alot of fish in this tournaments, even in the later stages they can still be around.
So i would suggest playing in quite small pots with marginal
hands and one pair hands as these kind of players could hit 2 pair with K4 and if you have AK on a Kx4 flop then you could go broke and have to try again. So i would suggest waiting for the 2 pair + hands and trying to win big pots off these players.
In the later stages when the antes become a bigger part of the game, most of the players do not adjust their game with the change, they will still open limp so when in later position you should be able to put quite a big raise in Pre and pick up the blinds and antes and money from any limpers.
Thats just some general ideas, i have a bit of experience in micro MTT's and would consider myself an MTT player if you would like some more advice i'll happily help
