I was talking more from a "don't be too eager to fight for tiny tiny pots" point of view. Is there really a lot of EV in calling when the best case scenario is a chop, and where the simple act of raising and calling only heightens the rake, so even if you chop, at least one of you loses?
Had BTN checked through in this example, the pot would have been 6.4bb, with 0.2bb in rake taken out.
BTN put in 2bb, gets 2bb - breakeven.
Hero put in 2bb, gets 2.2bb - you win 0.2bb or 0.01$.
MP put in 2bb, gets 2bb - breakeven.
In this particular case, after having raised, the pot is 15.4bb but the rake is 0.6bb.
BTN put in 5bb, gets only 4.8bb - loses 0.2bb or 0.01$.
Hero put in 5bb, gets 5bb - breakeven.
MP put in 5bb, gets 5bb - breakeven.
Prime example of why you shouldn't be fighting for tiny pots. Even if you get one player to fold, what do you gain, really? Less than 1bb.
I don't mind giving up a tiny pot like this to avoid the chance of looking silly when BTN somehow does show up with 3x, 6x or 77+.
I prefer fighting for tiny pots in better-looking spots (blind-stealing nits, 3-bet or 4-bet bluffing
light raisers, etc.).
The -EV of making a nitty fold in a spot like this is going to be pretty insignificant (especially if there's a % chance that BTN does in fact have 3x, 6x or 77+), and it might change your table image a bit so that you could later be bluff-catching a far bigger pot to compensate for the -EV now.
In other words: "meh".
