PT4 automatically calculate your all-in adjusted EV, which will tell you, if you are running hot or cold in these situations. Its something, a lot of people tend to get very hung up on, but in the long run it tends to level out, so it does not really matter. Its also only part of variance, so it does not tell you, if you have been lucky or unlucky overall. If AA lose to KK in an all-in preflop situation, thats no more unlucky than, if KK lose to AA, since the player with AA was lucky to be on the good side of a cooler.
