Hi, I think there is also a mistake at page 89, when the author calculate the EV of strategy 2 :<strategy2>=(3/7)(-5)+(2/7)(10.5)+(2/7)(-3) = 0
However, the -3 at the end I think should be -1, because for this part of the equation the action on the flop is check-call, then on the turn is check-check, even if idea the strategy was to go for the check-raise. So one bet is lost on the flop and that's all. So it should be -1 ? But then it does not equal to zero.
