Playing around with GTORB or other game theory software shows just how mental this really is, as the 'solutions' we've all reached are mostly a product of group-think, loss aversion, and wanting to make our lives simple.
A very good example of this is the hatred all regs have of calling marginal pairs OOP, especially on middling, wettish boards such as t85ss. Actually, scrap that, it's just as true on AK5r in late position. Take a look at this simulation, standard range for BB PF.
We have villain calling all GSs + on the flop, then all flushdraws and Ax+ on the turn, 50% of his Kx.
Our profitability of betting on the turn:
Obviously not all these hands will be in our betting range, but the point is that a ridiculous number of hands are profitable here, and that's with villain being fairly call happy with his Kx. Crucially, I think Kx calls very rarely. If Kx doesn't call, then we print money by betting 100% of our range on the turn. If it calls sometimes, we still make money betting any hand with a smidgen of equity, simply because of all the gutshots that fold turn. if they folded flop, then we make more money on the flop, if they call turn and river, we make more money on the river, etc etc.
Where the exploitation can come in, is that the reason x gets folded so much is because villain is expecting to be playing a 'competent' opponent. By competent, they mean one that they assume is going to make them indifferent at best in calling Kx. What I'm saying is, maybe we should be slightly less 'competent' in that regard, until people adjust.
The effect of over-adjusting for reverse equity is more pronounced on wetter, middling boards. I've done a CREV example with 97dd on 874cc BB-CO. Check calling the flop, VS a standard opponent and us playing standardly, loses us 2 BBs. In my opinion, the hand should mostly be folded PF, check raised on the flop, or check raised on the turn. In reality, the hand is virtually always called on the flop in order to fold the turn.
Because this blog is about aggression, not about our own adjustment to it, I'll give you the cliffs, which are that in position we need to be borderline maniacal with our barrelling frequencies, until we decide that a villain has adjusted. Alongside this, we need to be value betting and value bluffing very thin, giving us protection, keeping our options open for the river, not completely owning ourselves VS lighter calldowns, along with not handing our opponent the chance to control his own bluffing frequencies on the river. This would not be a factor if people were able to bluff into capped ranges by check raising and barreling, but they are not.
An extremely important factor in this is awareness of inflection points. The typical inflection point at 500 is on the turn, ie if the turn gets called then so will the river, except for those hands with showdown + good improvement potential. Typically the weaker the player, the more chance that their inflection will be the river, because they are less aware of the 'importance' of avoiding reverse equity spots and are more call call fold happy.
Tomorrow, I'll go over more barrel spots, in particular late position on very dry boards.
