Issues with GTO in MW Spots

Question 1

Why do solvers mix preflop?

Answer 1

Solver outputs are based on players knowing each others strategy. If some board coverage is missed, can be exploited

Question 2

Why might ‘pure’ preflop strategies be better than ‘mixed’?

Answer 2

Removing the assumption of other players knowing our strategy, makes sense to just play the better hands

Question 3

If BB overdefends (mixes become pure), what happens to UTG’s GTO strategy EV? Why?

Answer 3
