> For example, we are in BB at 1/2 and there is one limp and rest fold to us. Let's say we feel the proper bet is 15, but we instead raise to 14 so we only lose $2 instead of $3 ($14×2+1=29) if we take it on the flop.
That's a great thought. And I think it's a good example to work with in exploring whether it makes sense to take rake into consideration.
Ultimately, it's just math. Say betting $15 provides +$0.25 EV relative to betting $14 without taking rake into consideration. And say that 50% of the time you take it away on the flop. With $15, you lose $1 in rake compared to $14 50% of the time, so the EV relative to $14 goes down by $0.50 to -$0.25.
However, there is a lot of things to think about in poker. And you have limited mental resources. I feel like your mental resources are probably better spent thinking about other things.
Although I think it could be worth considering for some short stacked all in decisions. With rake, you need to have a bit more equity to justify calling. For example, let's say you have JJ and you think you're against a range of 88+ and AK. And suppose that your opponent goes all in for $25. Without rake,
you have about 52% equity. But with, say, a $5 rake, now you only have about 47% equity (settings / equity calculator / rake and tip). This becomes a lot less significant in bigger pots though. More like a 1% hit on equity. So ultimately, I think it is only really useful for the closest of calls.
