Now let's look at what the solver does:
1) Flop. BB folds almost all BDs, calls only AT of hearts, no XR. We don't need to defend BDFD on this board.
My first assumption was that it's because all offsuit connectors hit this board hard: T9o-54o all have at least a GS, and I thought that in tighter ranges, e.g. in a scenario where MP opens 2.5bb, BB has no T9o-54o, BD FD would become an XR. Which turned out wrong:
BB just don't need to defend them. Great.
2) Turn.
- No little XR on the turn, just XShove.
- When I put 25% of BDFD into the flop raise, Solver bets it all on the turn for 124% of the pot, no X.
- Really interesting that Solver XCalls all 33!
- 65o and 54o are either OB or XF. No XR here.
3) Aaand, ladies and gentlmens: River!...
after deleting XShove on the turn and forcing BB to XR as played:
BB:
MP:
To summarize. I still think calling 100% with KK is the best option here for the reasons I mentioned earlier.
