I just wrote out the payoffs for each player and then set the payoffs equal to each other and solved using a bit of algebra.
If x = percentage of attacking mid and y = opponent percentage of blocking mid.
The attacking player's payoff function is
x*(110(1-y) - 40y) + (1-x)(30y - 80(1-y))
So the defending player's unexploitable strategy is the one where it doesn't matter what value the attacking player chooses for x, i.e. it's the one where
110(1-y) - 40y = 30y - 80(1-y)
110 - 150y = 110y - 80
190 = 260y
19/26 = y
so that's how I got 19/26 or 73.08% blocking mid as the unexploitable strategy. Same idea to find the unexploitable value of x as well, just using the opponent's payoff function. I think this method of setting the opponent's payoffs equal to each other works for all zero sum games.
