why give a broad range to a chip leader in ep with no info on him, you have not seen any of his range or his style, why do most people assume the chip leader is playing loose ep ?? He may well be a strong TAG player .. with no info you are just hoping you are ahead , i prefer to shove my chips with some sort of idea where i am in a hand if my judgement is wrong i learn something from it, i can understand a shove if you were at a crucial stage chips wise but imo you are not and with patience you can find a better spot [with some sort of read]
i found it helpful in my game learning wise , when i could put people on ranges and how it would play against mine , hand reading pre + post flop is an essential part of anyones chances of improving. One of the ways i improved in this area was playing back my last mtts and using poker stove and gradually some of the figures started to come automatic,and also it helped my reading of betting patterns post flop.[playing back hand after hand]
