Lets think about this logically.
G1 - You know its Tuesday to Saturday between games, then a Sunday G3 - PON-ing G1isnt that much of a benefit as nmost people think - because there is a long break between G1 and G2 that the enthusiasm will trend back to 5. So Tie-ing this game doesn't bring as much benefit as what most people believe. THats why in regular season - TIE-ing the saturday game gives more benefit for the Tuesday game, compared to TIE-ing the Tuesday game for Saturday.
G2 - Sid can't risk playing POCT in this game, he essentially forfiets G3 by playing POCT in this game. This is the advantage that TAK has - TAK can do what he pleases in this game, because he knows he has the advantage in G3. maybe Akuma knows this as well, and will POCT G2, thereby winning in 2 games. ooooooooooo. I did this when i promoted
G3a - Assuming both teams PON'd G2, both walk onto Akuma's home court, with boosted enthusiasm from the previous day's game. Sid will have that little bit extra from the G1 - will it be enough to counter the HCA AND that Akuma has a better team? IMO - no.
G3b - lets say Sid AND TAK both POCT G2, and Sid wins. they will still walk into G3 with the same comparitive enthusiasm level - Thern the same scenario occurs as G2 - TAK has HCA and a better team and Sid will not be able to compete. THIS is why TAK has the advantage.
G3c - Sid PON'd G2 and TAK POCT'd and LOST - i dont think this will happen. Thats why TAK has the benefit of being able to POCT G2 and even if Sid POCT's as well, he doesn;'t lose much. Sid PON's G2 and TAK POCT G2 = TAK win.
I think Sid knows all the above and is banking on TAK PONing G2 - take the easy win, bank the enthusiasm and somehow try to win on TAK's home court in G3
THere may be one significant difference and that will be the game shape update on Friday - i will be VERY interested to see this.
