can someone give me an example of taking into account implied odds preflop and postflop, and overestimating implied odds preflop and postflop. i know this a huge mistake players make. Also how do i take in relation to my stack and size my opponents stack when calculating implied odds?

NL 5c/10c 6max
100BB's deep

A very cautious player opens to $0.40 in the CO. We have 22 on the Button, and the blinds are tight. We know this player HATES playing big pots without the nuts.

Against a player who stacks off a LOT on the flop, we would cold-call with 22 here all day, because we can expect to win his $10 stack often when we hit a set. However, against this guy, we might not expect to get paid at least $4 on our $0.40 investment when we hit a set, since he's timid post-flop, so it becomes incorrect to cold-call and set-mine. We would be overestimating our implied odds. Instead, though, we can consider a 3bet here PF, since he's timid and will fold probably more often when he should. Also, we can cold-call but NOT strictly for set value. On low or boards that might appear scary to the PF raiser, we can plan ahead to bluff-raise, if we know he folds too often to a raise on the flop. This way, we still set-mine, but when we miss, we can still pretend we have a monster on scary boards and he'll fold!

A sharp read on a player can change the 'standard' line from a cold-call to a 3bet PF.

what is a cold call, what is set mining, an what is a 3 bet?

You can't have implied odds preflop, that's just mad thinking. I agree with what raze says but that is not really implied odds thinking thats just just good poker thinking.

Impied odds is when you have seen a flop and your hand has the potential to improve significantly enough that when you hit on the turn or river you will be able to extract a much greater percentage of your opponents stack.

You are right in thinking that players make huge mistakes with implied odds because depending on your hand and what you are hoping to hit, it may be impossible to extract what you hope from your opponent. Players need to be vary wary with implied odds.

Cold calling is just calling a raise from a pre flop raiser.

Set mining is calling pre flop with a pocket pair, and hoping to flop three of a kind.

A 3 bet (pre flop) is when one person raises the blind, and another person re-raises him.

Tight player raises to 4BB UTG, you have 22 in the BB, everyone else folds.

If you are only 20BB deep, then there is no way you have implied odds to continue here, no matter how much of a donk villian is.

But if you are 100BB deep, then you probably do have implied odds, against quite a large number of opponents anyway.

I would say you can consider implied odds preflop.

DrQian: set-mining is certainly a form of implied odds I grant you but it is a pretty well defined strategy and IMHO doesn't qualify as implied odds. I suppose technically it is which is what raze was getting at. However when talking about implied odds this is not normally what is being thought about. However, the OP should understand set-mining and if you want to include this in implied odds I certainly have no objection.

Certainly it's not what most is generally meant by implied odds, but the 5/10 rule for spp/sc hands is basically worked out on implied odds. It's definitely not the same as postflop though, I agree.
