first 2 knuckles vs the last 3

Hi everybody today i red a book called:
"Championship Fighting
Explosive Punching
and
Aggressive Defense"
by Jack Dempsey



it is very interesting that Jack insist that we have to "Always aim with the second knuckle-the one next to your pinky-and LET THE OTHER KNUCKLES TAKE CARE OF THEMSELVES" so he means that we have to punch with the last 3 fingers.Me myself found it more natural and solid to hit with the last 3..I usually try to hit with the fist two but its not that natural to me and i have to bend my wrist cause otherwyse i feel pain in the wrist whe n hitting with them.Heres the text from the book i red about:




""Unfortunately, however, the hand-bone behind the little knuckle is the most fragile of the five backbones. It can be broken the most easily.
You must not attempt to land first with the little knuckle. Instead you must try to land first with the knuckle next to your pinky (the ring finger).
We'll call that the 2nd knuckle. Aiming with the 2nd knuckle usually brings about a three-knuckle landing. Those three-knuckles are: middle,
second (ring) and pinky. If you aim with the second knuckle, those three knuckles usually will land together because the average fist slopes
slightly from the middle knuckle to the pinky. Such a three-knuckle landing not only prevents the hand-bone behind any one knuckle from
bearing all the punch-shock, but it also permits punching almost exactly along the power line. Rarely will one of those knuckles make a solo
landing. But if you aim with the little knuckle, you risk a dangerous solo landing on forehead or blocking elbow.
Always aim with the second knuckle-the one next to your pinky-and LET THE OTHER KNUCKLES TAKE CARE OF THEMSELVES. They'll
take care of themselves all right; for the shape of the fist makes it impossible for them to do otherwise.
Clench your right fist and inspect its knuckles. Your thumb knuckle is "out of the way"-completely separated from your row of four knuckles on
the striking edge of your fist. More than that, your thumb knuckle is farthest away from your pinky knuckle-farthest away from the end of the
power line. Nature took care of that. Never double-cross nature by trying to hit with that thumb knuckle, under any circumstance. It breaks
easily. Keep it out of the way.
The knuckle of your index finger (the one next to the thumb) is fairly prominent, but not as prominent as the knuckle of your middle finger. In
some face-punches and in most body-blows, that index knuckle will land with the other three, for a four-knuckle landing. That's okay, let the
index knuckle come along for the ride. Under no circumstances, however, try to land first with that index knuckle. If you do, you'll not only break
your power line, but you may also break your wrist.
Beware likewise of trying to land first with the prominent middle knuckle-the source of most hand injuries. Such aiming will slant your hand off
the power line and, at the same time, endanger the middle knuckle and its hand-bone. When that middle knuckle makes a solo landing, its
prominence prevents the other knuckles from helping to absorb some of the punch-shock. That shock or pressure is terrific in any full-fledged
punch, particularly when you nail an opponent with a head blow just as he is stepping into you. In that split-second, your fist must withstand the
shock-pressure of an explosive collision between two hurtling body-weights.
Let me repeat: If your punch is landed correctly, in power-line fashion, the three knuckles-pinky, second and middle-will share the pressure
and distribute it over the three hand-bones behind the knuckles. That lessens the chance of bruising or crushing any one knuckle, or of
fracturing any one hand-bone.
Most professional and amateur boxers suffer hand injuries during their careers even though their fists are protected by bandages, tape and
gloves, because of unfortunate landings. As I pointed out earlier, the hands HAVE NO SUCH PROTECTION IN A FIST-FIGHT. You must land
correctly, not only for power-line explosiveness, but for hand protection.
We have examined the power line and second-knuckle aiming for long-range straight jolts; but what about other types of punches? What
about medium-range straight punches, and hooks and uppercuts? Does the power line and the second-knuckle aim hold good for them?
Yes, indeed, they do hold good, YOU MUST HIT ALONG THE POWER LINE IN ALL FULL-FLEDGED PUNCHES; AND YOU MUST
ALWAYS AIM WITH THE SECOND KNUCKLE.
The landing position of your fist may change from upright to sideways, in varying degrees, when shooting different types of punches for the
head. And it may change in various degrees from sideways to upright in punching for the body, BUT ALWAYS YOU MUST PUNCH ALONG
THE POWER LINE, AND ALWAYS YOU MUST AIM WITH THE SECOND KNUCKLE. You'll get the feel of that power line in other punches
later. You'll discover that bending the elbow, in a hook for example, does not break the line of power. And you'll find out why."""""


I would be very thankful the hear your toughts, experience and arguments about this question. :bbb

of course no problem.

 

u can still hit horizontal with the 3 fingers(and snap at the end) also u can hit vertical and still protect with ur sholder. But my idea is to look at the 3 fingers vs 2 fingers as a - and + for each other despite the style that you are boxing.
I think when hitting with the last 3 fingers is more natural, more solid, more stable, but u can mess up and hit with the pinky only and broke it. also the pressure is distributed over 3 bones not 2 (or sometimes 1 only the middle).
Thats my point of view.

 

its no need to compare boxer from as Dimpsey and today's boxer cause betwen them is whola difference (steroids and s.o.)

 

u talkin about power but its not only about power stamina/endurance are just that important and roids enchance them
