Hope Chess

"I've analyzed this thing to the best of my ability and as deep as reasonable, and now I hope that's all there is to it"

Hope chess is when your move is based on hoping your opponent doesn't see what you see. 

Not exactly. Hope chess is when you don't spend the time to make sure your chosen move is safe ("If I make the move, has he checks, captures or threats I cannot parry?").

But what if the result of a given game where to determine my eternal destiny? SHOULD i NOT THEN SACRIFICE MY VERY LAST BRAINCELL, EVEN AT THE COST OF TOTAL NERVOUS EXHAUSTION TO COME UP WITH THE CORRECT MOVE?   I think I better find a twelve step program.

Not true. "Hope chess", as Heisman uses the term, refers to moving without making sure to the best of your abilities that you can  meet all your opponent's checks, captures and threats. This has nothing to do with your definition.

Does hope chess float?

I have to be awake and focused to play non-hope chess for every single move of a game.  It's still hard for me to do if I want to do this every move (I don't know if better players find it comes naturally).

When I'm tired I definitely cut analysis short and think to myself "ok this move is good enough" or if I'm playing someone noticeably weaker "ok, this move is tricky enough"

I have the same problem. It's hard to stick to the correct thought process all the time, on every move, no matter how tired. I always feel quite depressed when I just made a losing hope chess move ("whoops!") though, so in the long run this helps quite a bit to stay disciplined. 

i never do hope chess, which is a big mistake

Never mind, missed a bunch of responses.

most of the time i play hope chess because playing up to 50 games and not got all day to play chess.

I thought HOPE chess stood for High Output-Poor Ending chess.

I read that in Heisman's book The Improving Chess Thinker.

He said that the level that takes the most time analyzing is the expert. Before then it drops off as you go down to beginner. Above expert it declines again because they just know the positions so well.

The hardest part is figuring a position out for the first time.

 Hah, that's pretty cool.

For the past few months now this expert at my club has been going on about how good play comes from less analysis and more in using your "long term memory"... maybe he's getting ready to push past expert.

Actually hope chess has to do with not taking the replies of your opponent into account, as in you hope your opponent doesn't have a good reply to your move. 

You can analyze the position and make a correct plan and find the "right" candidate moves. However, if you don't look what your opponent can do then it is still hope chess.

This is why Heisman suggests you start every time it's your move with look for your opponent's checks, captures, and threats before you look at those for you.
