with the blinds at 5/10 and 600 in chips you have 60 big blinds to start, this is above average for a live tourny but below for an internet tourny. you have more than enough to play tight for a while, but you have to find a hand eventually. i suggest to start stick to this formula
n=number of players at the table
2/n= %of hands you should play per round
example if there are 10 players 2/10= 20% or two out of 10 hands
8 players 2/8 = 25% or 2.5 out of ten hands
4 players 2/4 = 50% of hands
3 players 2/3 = 67% of hands
heads up 2/2 = all hands meaning no hand isn't worth at least a call of the bb heads up
with this in mind, you must pick the proper starting hands, at the beginning start with these hands not in the blinds
ACE TEN SUITED ONLY
KING JACK SUITED ONLY
JACK TEN SUITED ONLY
LATER ON AFTER THE BREAK IS WHEN YOU WANT TO OPEN UP YOUR GAME AS THOSE LEFT WILL UNDOUBTEDLY TIGHTEN UP A BIT.
ANY SUITED KING OR QUEEN
ANY SUITED CONNECTOR
ANY HIGH NON-SUITED CONNECTOR
you are going to want to change up your game after the break, raising much more preflop, and trying to steal as much as possible. since the rebuy is over most will not want to go broke and tighten up. the ones you really want to go after are the ones with the most invested, so try to pay attention to who is rebuying a lot and who looks desperate for a win. those are the people you can take advantage of. always remember pushing is much better than calling heres 3 reasons why...
1. they have to call
2. they have to have the better hand
3. they have to win
all these things must be in line in order for them to win. otherwise the pot belongs to you. remember:
IN NO LIMIT HOLD 'EM CALLING IS A WEAK PLAY
in terms of your competition, try to lump them in one of these 4 catagories
1. loose aggressive- play many hands and raise constantly
2. loose conservative- see many flops but dont make many plays
3. tight aggressive- play very few hands but play them very fast
4. tight conservative- play few hands and play them slow
for you to be most successful against your competition before the break, you want to play like a 3 if you think your competition to be superior and a 4 if you think your competition to be inferior. after the break you want to switch between a 1 and a 3 to keep your opponents off balance, in the tourny you described, playing like a 2 at any time is probably a mistake. and when raising preflop your raise should be between 3-5 times the blind mostly, only going all in with hands such as JJ, QQ, TT, and AK, these are the hand you either want to steal with or get in a coinflip situation, also if called many times you will be a dominating favorite.
The biggest piece of advice i can give you regarding any tournament is this....
A TOURNAMENT IS A MARATHON, NOT A SPRINT. IT DOESNT MATTER HOW MANY HANDS YOU PLAY IT MATTERS HOW LONG YOU LAST, SO DONT BE AFRAID TO PLAY TIGHT.
dont hunt for hands they will come to you eventually just use patience
