I'm playing around with PLO MM. And I keep noticing spots where it doesn't seem to matter at all what you do. For instance:

BTN vs BB SRP. Ks3s2d X/R50/C Kc BB?

If the BB plays optimally (R33 with 56.1% of his range), the EV of this spot is 11.19BB.

BUT they split almost every single hand. Checking range here is 11.159EV and BETTING range is 11.163?

I feel like almost ALL spots I come across postflop are like this. What is happening? It seems like it's nearly impossible to make a mistake against an unadjusting GTO player? That seems wrong!

Oh great theorists, please help me shed a light on this.

Much appreciated!

PioSolver wrote a good answer to this question in their FAQ, I'll paste it here:

Why do so many options, bet/check, raise/call, so frequently have basically the exact same EV?

This is one of the biggest surprises about gto solutions. It turns out that especially on the flop there aren't really a clear bets or very few of them. Usually the differences are quite clear between calls and folds (at least for most hands) but check/bet decisions and often call/raise ones turn out to be close.

It doesn't mean you can just start checking all those mixed hands or betting them as that would open a huge opportunity for the opponent to exploit you. This means it's a good idea to focus on general range composition for actions but not necessirily exact hands and frequencies.

Here's my take:

There are effectively an infinite number of strategies, and some subset of those satisfy the exploitability requirements of our solution. It should come as no surprise, especially in spots where there's a lot of game tree left, that there are many ways to play.

Thank you so much for this reply. It's been bothering me for ages :-) (And was starting to think I was doing something wrong).

Much, much appreciated!
