5 Introduction: The Puerto Rican Gambler Unmasked = an essay on Daryl's philosophy of improvising within structured routines - the 'conditional' of the title.
13 The Boomeranging Card of Mystery: Daryl's handling of the classic tossed-card-caught-in-deck-locates-selection. All the details that make this chestnut such a joy to behold when Daryl does it.
29 The Chicago Conspiracy: variation #1 of previous effect, this time without the tossing.
33 Quick Silver: variation #2, locator card is replaced by a coin.
38 Holding On!: Daryl does Alex Elmsley's Between the Palms with the (now-common?) kicker: the misses change to match the selection. Worth studying.
54 The Puerto Rican Triumph: another classic, with the now-famous topsy-turvy cutting display sequences. You decide if it's over-proving or not.
70 The Mysterious Cross of India: a coins-across effect with deceptively simple method, and perhaps the most important lesson in the book.
81 In the Pinch: selected card grabbed in mid-air as spectator dribbles a packet. This is so good that Martin Nash used it for years.
88 Just Tweezing: conditional handling variations of In the Pinch
94 Conditional Assembly: a nicely constructed four ace assembly done with A,2,3,4D.
105 Twisted Aces Redivivus: corrected/improved from the version in 'Paul Harris Reveals...' It looks good when Daryl does it, really!
