With 4 move odds, anyone playing White can do the scholar's mate: 1 e4 2 Bc4 3 Qf3 (or 3 Qh5) 4 Qxf7 checkmate.
So the 4 move odds is obviously b.s.
A quick Google indicates that, when the weaker player is at the master level, Queen odds are about 2000 ELO rating points and Knight odds are about 900 or more rating points, according to several sources. Since the best chess engines are about 500-600 ELO points higher than the best humans, that would indicate the best humans could beat the best chess engines with Knight odds the vast majority of the time. I got the following from Wikipedia:
Grandmaster Larry Kaufman [who has done extensive studies of the values of the pieces (his celebrated 80,000,000 position study says Q = 9.75p, R = 5p, B = N = 3.25p, P = 1p)] wrote the following about the ELO rating equivalence of giving knight odds:
[T]he Elo equivalent of a given handicap degrades as you go down the scale. A knight seems to be worth around a thousand points when the "weak" player is around IM level, but it drops as you go down. For example, I'm about 2400 and I've played tons of knight odds games with students, and I would put the break-even point (for untimed but reasonably quick games) with me at around 1800, so maybe a 600 value at this level. An 1800 can probably give knight odds to a 1400, a 1400 to an 1100, an 1100 to a 900, etc. This is pretty obviously the way it must work, because the weaker the players are, the more likely the weaker one is to blunder a piece or more. When you get down to the level of the average 8 year old player, knight odds is just a slight edge, maybe 50 points or so.
Basically I want to know more information about Stockfish 8 vs Human based on facts and not just opinions preferably.
Can Human (strongest GM'S, Magnus, Hikaru) can win any match say out of 100 matches or is it impossible now days? Can they still draw or is it impossible as well?
I've heard somewhere engine gives 4 moves odds beginning of the game and still beats human, is that true?
Sure Magnus or Hikaru can beat it with queen odds, but what about rook odds? Knight? Pawn? Odds
