What player in history probably has the best win to lose ratio?

So just to clarify: you're saying that during that 4000 game streak against children, you played no one else? Or played other people but beat all of them as well?

I was age 15 noone else to play except my brother.  The children were ages up to about 11 or 12.  

Before all this I lost more than 100 games in a row against my father but when I started beating him he did not play anymore. At that age I was more interested in bridge because it was a family game. 

I will admit that after the first summer I avoided playing chess until the next summer...

You have to realize there were not kids playing chess well back in 1956 so I had little or no competion. Nowadays it could not happen.

Things change, now with chess engine help it is near impossible to win all your games with Black in the Finals of the US Correspondence Chess Championship.

Interesting.

In the chessgames.com database Gioachino Greco has 79W/0L/0D, a 100% win rate.

Although it's true that nobody else knew remotely how to play chess in his time.

What world champion had the best winning percentage?

Paul Keres has the best win to lose ratio.  1021 wins to 210 losses.  His W/L ratio was, therefore, 1021 / 210 = 4.862 to 1.

Paul Morphy's W/L ratio was 4.416 to 1, whilst Capablanca's is 3.328 to 1.   Bobby Fischer's was 4.268 to 1, only slightly less good than Morphy's.   Alekhine's was 3.758  to 1 - better than Capablanca's and not as high as Fischer's.  Paul Keres was 4.862 to 1.  I have discounted the likes of Greco and Eichborne and anybody else with a seemingly perfect win record from my calculations, as, knowing chess as I do, I consider it highly unlikely that any chess player won every single game they ever played.  More likely our records are incomplete for those players.

I reached this conclusion by using chessgames.com as my resource, using the lost games as the unit "1" in the equation x:1, and the x part was how many times the won games could be divided by the losses.  I discounted the draws as being irrelevant to the question.

So I'd say the answer is Paul Keres, with an honourable mention going to Morphy and Fischer.  Most other players do not even come close to this record.

All this is not the same, of course as asking what player had the best wins to total games played ratio, as this question would have to factor draws into the equation, and might well change the overall outcome.

Bobby god.

In before the lock!

Patzaparov has stupid views on politics, I dont know how the hell you can go from chess champion to keyboard warrior.

Yup. It is harder to improve your rating from a reasonable level than to get  high rating if you are the same strength but starting out unrated.  My competitive games this rating period will take my national rating from 1935 to around 1980.  If I had started the season as an unrated player and achieved exactly the same results I'd have a new rating over 2100.

The old system used by the ECF is better than Elo-based systems in this respect.  Older games are given less weight (fewer of them counted) and eventually dropped altogether so you rating is much more representative of your current playing strength, and is very accurate for players that play a lot of rated games.

FIDE's system is rigged to ensure that huge swings of rating are difficult to achieve, and more difficult the higher your rating, because of the smaller K-value.

There are lots of weaknesses in rating systems.

Def fischer

What happened was that he declared that he wouldn't play anyone level unless he was first defeated at odds. There were those who unsuccessfully tried to seek a match with Morphy on level terms without a preliminary odds-match.

THE strongest and undefeatable player in the history is "BLANK"

fight me and i'll show you how to play chess

Morphy, no doubt

I am 77 years old and was looking over my record for all the years I have played chess.  I lost the first 100 or so games in a row when my dad beat me when I was age 8. After that I started doing better and better until he quit playing me.

In any event and counting the 100 games in a row I lost,  my life time record is approximately 85.5%

In the last 55 years I played almost all games vs Class A and experts and masters and grandmasters. My best record is against current grandmasters [100%]
