You have your opinion, and I have mine, GF.
Mine is that we are never going to win against a team like Hull who need a win to try to get into the play-offs and will be dominant in the game.
The slimmest of chances of us winning may be to get a breakaway goal and then sit on our laurels, but it will be very difficult to keep the score at 1-0 for the rest of the game.
If we "go for it" then we are more likely to give more goals away and we could be our own downfall in the event of Birmingham drawing.
Keep the game to 0-0 at half time if we can, and if we go a goal or two down then all hands on deck to prevent the score from getting any worse. Hull will be happy with that score anyway, they could not get anything better than a win, they have no chance of getting a better goal difference, they are way behind, and they will then let the game fizzle out.
