My closed bridge was recently critiqued by a strong player and the comment was made that my bridge could be improved by placing both sides of the heel of my hand -- the side that is an extension of my pinky, so to speak, and the side that is an extension of my thumb, so to speak (I'm sure that there are proper anatomy terms for these parts of one's palm/hand, but I haven't looked them up and it might be unhelpful to use them). My closed bridge has the entire side of my hand -- the side that you would use to make a karate chop -- firmly on the table -- with my palm facing mostly downwards, of course. But the part of the heel of my hand that is an extension of my thumb tends to be just slightly above the cloth -- for common center ball and draw shots. I'm not talking about an elevated closed bridge position -- I'm just talking about bridging for a standard center ball or draw shot. I find that when I try to get the entire heel of my hand -- both sides -- firmly down on the cloth, I can't make a comfortable closed bridge. It was explained to me that if I curled my bridge arm and hand a bit -- kind of like left handers often do when writing with a pen, it would then be easier to get the entire heel on the cloth. This does seem to be the case, but the position is awkward, as I am used to an extended left arm (I shoot right handed). Might anyone tell me that what I'm doing is okay, and that there is plenty of stability so long as half of the heel is down, or is the chorus that I should have the entire heel on the cloth? BTW, I am not implicitly asking whether I should use an open bridge more often, or about the pros/cons of open and closed bridges. I'm focused solely on the specific configuration of the closed bridge. Thanks in advance for any input/thoughts.
