Ok, I am going to take a very, very simple pokemon scenario and do the mathematics to show you exactly how much skill and how much guesswork does go into pokemon, and so like you have an example you can follow in case you encounter a similar situation in future.
For any situation in pokemon there is a strategy where whatever move your opponent selects they cannot improve their chance of winning above an arbitrary point (before the teams are selected this point would be 50%). Against a perfect opponent this is the perfect strategy. Read
here, for more detail.
Anyway, I decided to use an example I remember from a game in an early DP tournament that I lost. Because it was a particularly good one.
The scenario was this. I had Heracross and CB Tyranitar, my opponent had only Scarf Garchomp. Garchomp has very little health left and can be KOed by any attack from either of my pokemon, but it outspeeds both.
My Heracross had just KOed my opponents last other pokemon with close combat. This is important because it lowered my defense, meaning with the health I had remaining Garchomp would be able to KO me with earthquake. However if I switch and switch back, I would be able to survive an earthquake. Even without a defense drop Garchomp is able to KO Heracross with Outrage.
Tyranitar has enough health to survive one Outrage but not an Earthquake.
So, disregarding anything other than the most likely outcome, the problem is essentially: if I switch and Garchomp Outrages I lose. If I switch and Garchomp Earthquakes I win. If I attack and Garchomp Outrages I win, if I attack and Garchomp Earthquakes I lose.
However thanks to Sand Veil, CHes, and the possibility of Outrage causing Garchomp to hit itself in confusion with its third outrage the maths is a little bit more complicated than that. (I have simplified some of the calculations a little, the fact that Garchomp can keep hitting itself for 4 turns while I keep missing would take too much effort so I estimated a couple of these).
If I switch and Garchomp Outrages, I have a 18.75% chance of winning and my opponent has a 81.25% winning
If I switch and Garchomp Earthquakes I have a 75% chance of winning and my opponent has a 25% chance of winning.
If I attack and Garchomp Outrages I have a 79% chance of winning and my opponent has a 21% chance of winning.
If I attack and Garchomp Earthquakes, I have no chance of winning at all.
Here is a table:
Code:
Outrage Earthquake
Attack .79,.21 0,1
Switch .1875,.8125 .75,.25
Whoo boy, I think I am over my head explaining this. But I will soldier on..
Anyway, what I want is a strategy whereby whatever strategy my opponent employs he cannot improve his likelihood of victory. What this means is that the expected return of either move he selects is exactly the same.
E[x] is the expected value of selecting a move.
p is the probability I should attack.
E[Outrage] = .21*p + .8125*(1-p) = .21p + .8125 - .8125*p = .8125 - .6025p
E[Earthquake] = 1*p + .25*(1-p) = 1p + .25 - .25p = .25 + .75p
so E[Outrage] and E[Earthquake] are equal when
.8125 - .6025p = .25 + .75p
.8125 = .25 + 1.3525p
0.5625 = 1.3525p
p = 0.415896
I should Attack 41.5896% of the time.
For my opponent:
q is the probability he should Outrage
E[Attack] = .79*q + 0*(1-p) = .79q
E[Switch] = .1875*q + .75*(1-p) = .75 - 0.5625q
.79p = .75 - 0.5625q
1.3525q = .75
q = .55452865
He should outrage 55.452865% of the time.
If I had played according to this strategy I would have had a 43.807767% chance of winning.
However, you must also consider that this strategy is only optimal if your opponent plays optimally. Which they will not do.
It could have been possible my opponent hadnt realised that my defense drop had put me in KO range of earthquake. Though he was a very skilled player. This made me think perhaps I should be more inclined to attack.
It is also extremely unlikely he would be able to calculate the exact equilibrium during the battle, generally in such clear cut situations as this one I expect people err towards 50/50. Also I couldnt calculate it either. The best I managed was to notice that if I predicted wrong, by forcing him to outrage I would still have a 25% chance he would hit himself in confusion. Which suggested perhaps I should be more inclined to switch.
In the end I switched and he Outraged. I cant remember if I tossed a coin for that one (which I do do sometimes), but I remember I thought about it for a long time. I still wonder if I overestimated him and that he outraged because he hadnt noticed the def drop. But I dunno if I'd trust him even if he told me.. So I guess I'll have to remain in the dark..
Your Blissey vs Kyogre scenario is significantly more complicated than my example (and you havent given us enough detail to analyse it properly). But it seems like the Blissey should have softboiled and then softboiled again against Scizor.. I am unsure if Blissey is enough of an immediate thread to Kyogre to expect with any confidence that Kyogre would switch out..
So basically I am with Obi, Colin and Aldaron. There is luck in prediction but there is skill also.
Have a nice day.
