Based on what games? Bullet and blitz games don't count as humans can easily make very stupid mistakes when short of time. We need a minimum of one minute per move to avoid the worst thoughts we can imagine. A minus knight removes so many resources for the handicapper. It frees the human mind of troubles.

if there are more quarks in a proton than atoms in the universe and they can be manipulated and energy supply is not an issue, then maybe chess can be solved as early as this or the next century.
You have an easy method to detect a quark? AND store information using it? And addressing it in a 3d space? :)

Such is not even in physics discussions anywhere at all, no matter how far one is extrapolating into the future (at the moment).

How many atoms do we use to store a bit today? How many atoms for the pathway from that storage unit to the detector?

At TOURNAMENT games. I watched Topolov, for example, blunder a queen to a move I saw instantly. After making the blunder, the next move he had to give up his queen or else be mated on the next move. Use a computer to go through GM games, give them an hour per move, which is hardly up to the standard we call "perfect" and see how many mistakes are made. Usually mistakes that the opponent fail to take advantage of because they didn't see the punch line either...

As it stands, I have no idea whether a knight is a forced win or not given perfect play by both sides. But even without knowing that, I know how prone humans are to make mistakes so that I consider the chances of a GM winning with a knight handicap to be far worse than for a perfect player winning. How much worse is "far worse"? No way to know at the moment since there is nothing even remotely approaching perfect play if we go beyond 7 pieces left on the board, total.

a).Would it be a win for the knight up (with perfect play), because it can bring more power to bear down on the opponent and can always use to win.

b).Since it will be perfectly defended, it will be a draw, and all the other activity aroumd it during the game, will be defendable, even with the extra knight bearing down on it.
The correct answer is definitely a). The extra knight does not come out only at the end of the game but is there from the start and that advantage can be wielded from the start to gain further advantages. Regarding b), no defense will ever save a lost position against perfect play.
But with humans, we have always understood that a piece up, if before the very end, is only a matter of technique to win.
And it is.
Would this be different with perfect play?
We already see it today with top computer games (e.g. in TCEC), that it is often often a draw.
No, it will not be different if the losing side plays "perfectly".
Obviously blunders by the GM will be punished harder, but if the GM plays carefully and avoids unnecessary risks, he should be able to avoid blunders. (And just forget what Bob will respond to this.)
OR is this because computers still have a long way to go, and then, when perfect one day, they would always find that way to win.
In a lost position, all moves are losing. So in a lost position, perfect play won't magically help the engine find a drawing move.

Of course, NOTHING has proven that a knight handicap is losing. That's merely an assumption.

So much better to forget what Ronald is saying since it is 100% speculation even though he proclaims it to be an actual fact. However, conjecture != fact.

Please learn to read. (a) and then he asked a specific question about (a), not (b). However, BOTH "answers" are unknown and only guessed at. That has not changed regardless of your nonsense claims with no evidence to support them.

I guess humans would blunder now and then but it wouldn't change the score completely. The more difficult the position is, the easier it is to make a mistake. A knight off helps us an extreme amount. From the start humans could play in a totally different way than normal. No need to fight for the initiative or to defend accurately. Give a pawn to trade some pieces and maybe another one too to get an endgame. Then just play for a win with a basically guaranteed draw in the worst case.

I understand your difficulties admitting you lost track of the discussion. Or for that matter, admitting anything.

Well actually, no I do not understand it. That part of your psychology is certainly not part of mine. I have a sense of honour.

But not any "common sense" to see the difference between conjecture and fact. I'd think that is an absolute prerequisite for being a lawyer.
