Hi Scylla, I'm having trouble understanding the EV calcs of the solver.
I ran the solver (at 0.5% dEV every time), and the EV was 8.3/20 for BB, looking at the first node before any action has been taken.
I then locked the BB's strat on EVERY street. Then the EV was still 8.3bb/20 after I ran the sim again.
So I wanted to see how GTO - without adjusting - would fare against a bad opponent.
I changed the flop 2bet range of the BTN so that any non-set hand (that was originally 2bet in a GTO strat), was called or folded instead. If a hand was mixed between calling/folding, i would call it 100%. If a hand was raise or folding, I would fold it 100%.
so i locked that strat for BTN in that first action facing a flop bet, and let him play GTO with the rest of the tree. Here it shows that BB's EV is now 8.32bb/20, a net gain of +0.02bb. But scanning through the tree, I don't see how this gain is made. Here is my maths and the bit i would like checked please:
The BTN folds 1% more. When BTN folds, BB EV is 20. So net gain in this tree is 20 * 1% = 0.02bb.
We can then immediately see that When BTN raises 2.63% of the time, BB loses EV. Also when BTN calls, BB also loses EV. So where does BB's gain in EV come from (when looking at the first node)?
EV of GTO both sides
EV of BTN adjusted flop 2bet range, GTO rest of tree.
