Top 3 most defensive, cautious and conservative grandmasters?

1. Karpov

2. Petrosian

3. Kramnik

Is my ranking right? Or Petrosian at number 1? Any other defensive players?

Petrosian...No doubt...

The reason why I put Karpov over Petrosian is that Karpov's repertoire looks more defensive than Petrosian's repertoire.

1 Petrosian very defensive

2 Karpov defensive sometimes attacking

3 Kramnik

1. Ulf Andersson

2. Alexander Khalifman

3. Peter Leko

Some less known draw masters (at least at some occasions): Peter Szekely drew all his 13 games in the Capablanca Memorial Premier I group in 2003. His longest game was 13 moves, the shortest six moves. Istvan Bilek drew all his ten games in Slupsk 1979, playing 125 moves and spending 109 minutes.

Leko HAS to be included.

1. Ulf Andersson

2. Peter Leko

3. Petar Trifunovic

Interesting! Thanks for sharing!

Petrosian

Leko

Karpov

1.Fischer

2.Kasparov

3.Petrosian

Fischer?????Impossible!!!

petrosian for sure...

Actually, I believe in MGP by Kasparov, he writes/quotes: Something like Fischer played/chose openings that gave him easy equality, but he won since his opponents made mistakes: In other words, he handled sterile openings dynamically.

Some food for thought.

How about Anand? He is cautious, often going for a draw.

These days, but I still remember the days where he played real chess.

The three names that come to the mind first are Anatoly Karpov, Peter Leko and Ulf Andersson.

Lasker, Petrossian

Ulf Anderssen. From the early 1900s, Schlecter.

I wouldn't include Korchnoi.  He is a counter-puncher and is slow to take the initiative, but he will make provocative moves and is quick to grab a pawn even if it means submitting to a strong attack.  He doesn't play it safe.  I would put Flor on the list.
