I don't have any of Duffie's work, and I read that this is the book to get when it comes to Duffie. I bought it as a special offer elsewhere, and its really, really good.
Alot of effects contain dealing. Sometimes spelling is used ( combined with mathmatic priciples ). Sometimes dealing is used to mix the cards ... etc.
Standard sleights are not explained. Sleights like Elmsley count, Vernon Add-on, Faro, Reverse Faro ( even its not a move, but the term is used ), half pass and double lifts and false shuffles, are needed, but not explained.
I loved some effects, and liked others. I know I won't use some of them though, because they look more like puzzles, than a magic effect. I'll review the effects I use:
Kickstart Aces: Spectator locates the aces with a help of magic card. A VERY neat, clean 4 of a kind production. The spectator locates the aces in a very clean way. Its has some prepration,which can be done if you know how to cull effectivly. Other than that, its a winner.
Sweet Sixteen: Though the effect is fun to do, the plot itself is not the best. You show 4 cards, pointing out they are 16 in total. You turn them face down, turn of them face up, count the cards and the face up 4 changes to 2. You do another change, getting two 2's. You say 16-4 = 12. So I should have 12 left! No! I have TWO 12s! ( i.e queens ). The plot is not the best, but it might be nice to do once in a while.
Six Cards Interlude: any deck is shuffled, then top six cards are taken. One is fairly selected, and revealed later one. You never touch the cards, you don't have to be there anyway. You can instruct your friend in the phone! The effect takes awhile to do ( dealing and transfering cards ), but its *nice*.
By Pass: A very quick effect, which is really fun and nice to do. Two cards are selected, You take produce one from your pocket and the other is reversed in middle of the deck. The method *flows*, and is really quick. A very good card control is taught here, which is something I will use.
Halloween Location: A selected card revelation thought a fair process. Again the dealing card be boring here ( I've had the spectator dealing 45 cards once, his card is 46 .. )
Fact or Fiction: One of my TOP favorite effects! THIS IS the lie detector I will use! Its simply brillant! Performed it 4 times, each time got a kick out of it! There is some setup, but the effect is well worth it.
Make Mine a Double: An extremly clean way to produce 2 cards of the same suit and value. Spectator chooses a card for you, then a card for him. Both are the same in value and suit. Very simple method, very direct and quick effect.
Totalizator: As it reads, 2 value's of the selections are summed, and you produce two cards with the same summed result. Easy and direct. You will use it if you like the plot.
The Mental Pack: A card and a number are selected in a fair way, and the number is *produced*, and so is the card ( in a visual way, like in the standard card sandwich handling ). I will use this, though I'll use a short card instead of the crimp ( I'm telling this in case you bought the book! ). Some setup is needed, but well worth it for the effect. I use this in my performances.
Hour Magic: A little quickie for you to use. I don't use it in my performances, only in *here is my deck. Show me a quick trick* situations. Borrowed deck, no sleight of hand.
These are the effects I read and use. I didn't have time to read the others, I will do since holiday is coming. For now, some effects here are really amazing, while others are like *nice .. *. There is something for everyone here.
