poker is strange, everbody knows how to do. no sarcasm in it. i totally agree the first two posts. if you play very tight you can just wach a few guys eliminate themselves but later get lost under huge stacks. if you are shortstacked when u arrived, only strategy is praying. if you are chip leader you can bully others.
but if you are not shortstacked and have enough chips to scare, you can play a little agrresive. in final tables top 3-4 get decent money. of them, one usually plays loose aggressive, others play only good hands and sometimes steal blinds. middle stacks too play like that, aggressive players get eliminated or make good chips. but usually at most 4 players are in game, more usually 3 players play a hand. so a A6/K9 / 67s cards are really good cards in those situations. to win, or to be top 3, i think u must be more aggressive and trust such cards more than other times.
