When we play in Mtts where players mob are more than 1000. In my case it is near about 5000 in 888poker freerolls. Our main aim is to survive few rounds against All in freaks then try to build decent chipstack. Now I start my freerolls from 1000 chips and then try to build it more and more.Once game enters into Mid level say from Rookie to experience player then the real test of knowledge takes place. This time mostly say 4000 players r out of the game. Only 1000 survives. Now at this level our strategy is to play few
hands but quality one only. Time passes .. Now only around 500 players remain. Competition get tough as we r among pros. No one in the mood of easy surrender. Here Positions and hands and Chipstack matters. If we somehow survives in this level then we r in final 50. At this level chipstacks r of decent size. Here Mental games take place like 3 bet raising and shoving. And in final 9 it is more about mental toughness and skill.
Now Mental ability and skill improves with experience only. I mostly manage to move deep into tourney. The key is if u play tight u r mostly manage to move deep in tourneys. But the disadvantage is you will have lower chipstack than other players that is why u will not last longer in final 50. Now if u play aggressive chances of getting out early is high.
So the ideal strategy is play tight at initial stage of the game then play aggressive at middle stage of the game and in the final 50 play according to the table behaviour. I.e. if at a particular game table 5 out of 9 players playing tightly then just try to steal the pot with decent cards. Use shoving techniques against them . But if u r among aggressors then be a tortoise and play only Nuts. Never exempt low stacks at mid level of the game.
In the end experience with little luck would bless u.
