I've never bet against my country before and I do feel mildly odd about it, but not half as bad as I thought I might. In fact to be honest, I feel like a naughty schoolboy sticking his fingers up at the headmaster behind his back. In contrast, I've never bet against my club side, Arsenal, and would never even consider it.
If called upon to justify the bet, I'd say that a) I think it's +EV, b) I'm sick of the English FA and the stream of useless and self-serving managers they appoint, and c) this ramshackle and incompetent organisation has let me down every 2 years now since 1970, and THAT'S A LOT OF LET DOWNS!

I'm interested in other people's views on this. Anyone else laid bets against their home nation? Anyone think it's almost a hanging offence?
