...a little more on call/donk-bluff as defense v. steal attempt

here is the decision tree i used for this analysis:


here is the spreadsheet showing the 'worst case' ev of a donk bet. some general observations are:
  1. the roi on our 6bb 'investment' can vary from +54% to -80% depending on opponent and board texture. 
  2. dry flops are generally better than wet, but are also more exposed to bluff %,
  3. A - high and 2-broadway flops are bad, but are more protected from bluff %,
  4. ...more?

if you look at that decision tree, you may notice the alternate path for bb response to a btn flop raise. it wasn't used for the #'s in the spreadsheet, but is the beginning of accounting for our hand value and developing a more complete donking strategy. if anybody wants the .stx file, or has other thoughts or ideas on this, let me know.

  1. Dumb question time. I've never heard the term wet or dry flop before... what is it?

  2. A dry flop is a flop where there are very few if any draws, an example would be something like Q,7,2 of all different suits (rainbow) another example might be a paired board like J,J,4 rainbow. On the other hand a wet flop is one where a bunch of different draws are possible, J,T,4 with two of a suit for example.

    The reason this is important is that a wet board gives your opponent many more possible combinations of hands that are willing to continue to fight for the pot. A dry flop helps fewer combinations of your opponents hand range so he is less likely to have a hand to contnue.
