Here's my take on it, as semck's teammate who just lost hopes of winning the cup:
Way to go semck!
Obviously this was not the optimal result, but given the circumstances, it was the best available. Think about it from the point of view of each player. Germany wants the solo and, failing that, a two-way draw. Italy wants to make it into a draw. Assume for now the Turkey's motives are unknown, other than that he doesn't want a German solo, as they were. For Germany, Italy is offering to throw the game, and he sees that the quickest, safest way to do that is a convoy to Rome. Anything else is likely to alert Turkey, give the two of them a chance to stop it, and make the three-way the most likely option. A three-way is the worst possible outcome for Germany, so he will refuse any less direct throwing method for fear that its likelihood will increase. That leaves Italy with two options, convoy or don't convoy. If he convoys, Germany will continue to back off, increasing the incentive for Turkey to go for the two-way, which is likely his preferred outcome. Given that Turkey has made no attempt to back off for the last several years, and clearly isn't taking Italy's threats seriously, Italy has to assume at this point that Turkey wants him dead, and that Germany's going to be continuing to back off, making it impossible for him to throw in the future. This makes throwing the only viable option.
The rest of you are seeing this from the outside: "He just cost us our chance at winning." You all would have preferred the two-way, because it would have given your team a better shot at winning the tournament, and that too is logical for you. You should not, however, blame semck for acting in the best interests of his team rather than the best interests of your team.
@Yonni, I'm sure you remember the game I threw to you in a very similar fashion because there was a third party still madly driving for a solo. You obviously understood (and appreciated) my motivation there, and the third party did too, once he had some time to cool off. Why is this game any different?
