I love it!
I'm way into the pschology part of the game myself.
Another great one is when playing dwarves, show your opponent the engineering runes and say: "This valiant rune is very handy! It makes the crew unbreakable."
Do that and you don't even need to purchase a valiant rune.
Something that really helps as well is making your opponent know you know EVERYTHING there is to know about the game and how to play it.
Obviously it helps if you do know the rules and know the scores off by heart such as: "S4, T3, I wound on 3+, your armour save is -1 (and if you know his armour save, tell him what it is too).
When he knows you know, he'll assume your game playing is outragiously great as well.
And then you've already won half the game!
Great article.
