In this particular scenario, I shove for the following reasons:
1) The villain has made a small 5-bet, taking into account the sequence preflop, which makes me suppose that this player does not play in a balanced way, so if I want to level myself I must strive to detach myself from said concept against this V.
2) Hero's 4-bet also denotes small size, considering the sequence preflop. This reinforces the idea from point 1). At the moment we are on the same page with BTN (we are leveled).
3) Actually it is a stage prior to the previous points and we refer here to the information we have regarding this V. Apparently we have not obtained enough readings. And what we really have left is one thought, regarding the probability that this villain has to "traps" using small sizes, to hide very strong
hands preflop.
If we really don't have enough information to make affirmations like: this V managed to fool us with AA / KK. We are closer to continuing.
I agree with the previous post. It makes no sense to call when our SPR before acting is less than 3. It is really preferable to fold before calling and when our opponent has no fold equity.
