I have been working with coins a lot for the past two or three months.
I have been going through bobo's and I hear a lot about how the Tenkai or Goshman pinch and deep back clip work much better than a backpalm. I have not seen this sleight in bobo's (I have the paperback version).
I am fine with backpalming I've worked on it for a while to make it look natural. Are there really a lot of advantages/ disadvantages to tankai/Goshman Pinch. Also where can I learn this? I'm planning on getting revolutionary coin magic does jay have a good explanation for it?

I use Goshman pinch instead of backpalming a coin because it frees 3 of my fingers if you know what I mean. With the backpalm I can really only move my thumb and that would telegraph that I am backpalming something.

A good source and application for the Goshman pinch is on Gregory Wilson's On The Spot. Though, I believe he credits Jay Sankey. It involves 3 quarters traveling from one palm to the other by magic.

I hate the Backpalm. It's just not practical. I use Tenkai Pinch and Deep Backclip just because you can accomplish the same stuff.

buy jay sankeys revolutionary coin magic he will tell you so many ways to use the goshman pinch and how to get in and out of it it is a very good dvd.

I agree with everyone else. Tenkai pinch is the way to go. at least for me it is.

i know the basic workings behind it the angles are slightly worse but yes i see all of your points thanks

In England none of our coins are big enough to be back palmed so I use the tenkai pinch instead. It has the same amount of movement and frees up more fingers and looks a little more honest in an open display I think.
