Career supertournament wins by player
Updated 30 April, 2014

Kasparov: 40
Karpov: ?
Kramnik: 23
Topalov: 21
Anand: 21
Carlsen: 21
Ivanchuk: 15
Gelfand: 11
Aronian: 10
Karjakin: 4
Caruana: 4
Grischuk: 1
Nakamura: 1

My definition of supertournament is quite broad: any closed international event with at least two players who have been in the top 10 in the last year constitutes a supertournament. Neither matches nor rapid/blitz events count as supertournaments, regardless of who is playing.

If there is a tie for first, it will be counted for all players involved unless the tournament used tiebreaks, in which case only the player they declared winner gets to count it. Please see posts below for details on the events considered but not counted for this list.

Also, for what it's worth, in case of a tie, the first player to reach X supertournament wins will remain listed higher.

Kinghunt: 25... Qd3 instead of 25... Qd2 would mean that the final perpetual check couldn't happen, as the queen would guard the f5 pawn and prevent it from being taken. However, white would not be forced to play into the same line, and black would likely have a relatively small advantage.

  Kinghunt: <My proposed world championship format>

There are <six> Candidates, selected as follows:

1. World #1 by rating
2. World #2 by rating
3. World #3 by rating
4. World Cup Interzonal Winner
5. World Cup Interzonal Runner-up
6. Organizer nominee

FIDE picks its rating qualifiers by average rating. I would pick them as the players who maintain the highest live rating over any 20 game period. Only games played against foreign GMs count towards the 20 games. This would incentivize playing more games and risk taking, as only their best 20 game period is considered.

I would change the World Cup from its current KO format. Keep it at 128 players, picked in the same manner, but make it a 14 round Swiss. This would allow it to be quicker, eliminate the need for rapid/blitz tiebreaks, and reward aggressive play, rather than aiming to drawing to force tiebreaks. If there is a tie at the end, head-to-head is the first tiebreak, followed by average opponent rating.

The organizer nominee must have been ranked in the top 10 at some point since the last Candidates, either officially or by live rating.

__________________________________

The Candidates themselves are a 6 player QRR (20 rounds total). It may be divided between two cities, or otherwise have a long break introduced in the middle to reduce fatigue.

In case of a tie, the default tiebreak is a classical six game match for no additional prize money. One player receives two extra whites, and the other receives draw odds. If both players want the same side, they have a standard tiebreaker rapid/blitz playoff, and the winner picks what side of the match they play on. Upon request from <both> players, this entire match may be replaced with a typical rapid tiebreak.

___________________________________

The match itself is best of 18 games. The challenger gets 10 whites, and the champion only 8. In exchange, the defending champion receives draw odds.

___________________________________

This system has minimal events to organize, is open to everyone, and should do a great job picking the best challenger. It could be easily implemented on a biannual basis, with the Candidates and title match occupying the same calendar slot in alternating years.

  Kinghunt: List of Candidates Winners and world rankings, 1950-1990

1951 - Bronstein - World #1
1954 - Smyslov - World #1
1957 - Smyslov - World #1
1960 - Tal - World #1
1963 - Petrosian - World #1
1966 - Spassky - World #1
1969 - Spassky - World #3
1972 - Fischer - World #1
1975 - Karpov - World #1
1978 - Korchnoi - World #2
1981 - Korchnoi - World #2
1984 - Kasparov - World #1
1987 - Karpov - World #2
1990 - Karpov - World #2

All winners were the highest rated players in the world (besides the defending champion), except for 1969, when Spassky was behind Fischer (who didn't compete) and Korchnoi (who Spassky defeated in the Candidates Final).

This suggests that the old Candidates format can be replaced with a much, much shorter one where players are picked by rating. I will post one such concrete suggestion soon.

  Kinghunt: From Gelfand vs Aronian, 2013:

<An interesting idea is to look for a surprise down the line. But how do you define a “surprise”? One possibility is to be able to find a good move that the opponent, human or machine, does not see. And one way to do this is to be able search to a deeper depth than the opponent, but I don’t see how this is any different than seeing farther over the horizon than the opponent.>

I have given some thought to this, as it may be the best way to tune engines to play well against humans. (Not that they need any help, but they may get better results by not jumping at so many incredibly hard to find threats.)

I think a "surprise" may be considered as a move that causes a drastic evaluation shift above a certain depth. Suppose an engine searches to d=24, and has two moves that it evaluates roughly the same. Normally it just picks whichever one is a centipawn higher. But I think it can do better than that. It should play the move that scores <worse> at lower depths (say, d=18).

The idea is simple - if the evaluation has risen with depth, it means the engine refuted several defensive tries - defensive tries that seemed very plausible even at d=18. Anything engine approved at d=18 is likely to tempt a GM, or at least make them spend time thinking about it.

Let's make this a little more concrete. Suppose we have the following position, black to move:


click for larger view

Let's say the two candidates are 17...d5 and 17...O-O. At d=18, we get the following lines and scores:

17...d5 18. g6 hxg6 +1.25
17...O-O 18. g6 d5 19. +1.77

Then say the engine runs to d=24, and gives the following:

17...d5 18. g6 hxg6 +1.13
17...O-O 18. Rdg1 Rfc8 +1.15

I would argue that the engine should choose the second line. Why? Because the opponent is going to be tempted by 18. g6, as was the engine at d=18. However, at d=24, it found that after 17...O-O 18. g6, it has the resource 18...Bf6!, which drops the eval to +0.78.

That is how an engine can detect "surprise" and use it to "trick" its opponents. It risks very little, as at full depth, the moves evaluate similarly anyway.

It is, of course, a matter of parameter tuning to determine when two moves evaluate "close enough" to employ this strategy without undue risk, as well as the lower search depth being compared with, and some kind of function to integrate the two.

I would appreciate any and all feedback on this idea. I may cobble together my own version of Stockfish with the move selection changed in such a manner to be deliberately difficult for humans to play against.

  Patriot: <Kinghunt> Here's a copy of my response.

<That's an interesting idea. So if it happens to be losing it goes with a move that is actually better for its opponent while giving them a tempting way to screw up, since their limited search depth only allowed them to see how "great" 18.g6 is. Very clever!

That's sort of the way strong human players play. When they are losing they may go with a crazy move that is worse but gives them the best chance to get back in the game. After all, they are only going from "lost" to "dead lost" if it doesn't work.>

  Kinghunt: I don't think such a strategy has to be limited to when losing, though. I could imagine the same system giving very good results whatever the evaluation.

For example, consider this position:


click for larger view

White to move

Let's say the two candidate moves are 18.Ra5 and 18. Bh6. At d=24, we get the following lines and scores:

18. Ra5 O-O-O 19. Rxa7 +1.05
18. Bh6 Na4 19. Qh4 +1.08

However, at d=18, we have these:

18. Ra5 Qb3 19. Nxe4 +0.72
18. Bh6 Na4 19. Qh4 +1.03

Clearly, something changed dramatically in calculation of the 18. Ra5 line. Indeed, if you take the start of the 18 ply line to 24 ply, it finds the resource 19. Rfa1, which brings the evaluation to +1.7. Thus, 18. Ra5 is considered the trickier move and should be favored.

  Patriot: <Kinghunt> <I don't think such a strategy has to be limited to when losing, though.> Very true! I guess if I was the programmer one of my big concerns would be that the more "heuristic" logic interjected into the main calculation function, the slower it would be and would have a more limited horizon.

It may have something that goes "IF d>=18 THEN Trick_Eval() END" so the more complex logic is bypassed until it reaches that depth. But even such a simple statement could have a dramatic effect since it will be executed billions of times.

It's not to say it won't work--that's just a concern that I would have to test. Nonetheless I think your idea is brilliant!! It's definitely something worth looking into.

  Kinghunt: Yes, this may also require MV analysis, which would also slow down the search. I guess it's a question of which would have a larger benefit: the slight increase in accuracy from getting in one extra ply in "normal mode" or the extra trickiness playing in "anti-human mode."
Mar-15-14
Premium Chessgames Member
  OhioChessFan: I have had ideas of engines using surprise moves. Your idea seems pretty straight forward and captures most of the important variants. As for your extra ply vs trickiness, an extra play isn't an extra ply. In some closed positions, one more ply is almost meaningless, whereas in an open position, it's crucial. But I would guess it's the open positions where the trickiness factor is also most important. I don't know if an eval factor could include an appeal to the type of position on the board before invoking the tricky subroutine, but it's an interesting thought.

  Patriot: <OhioChessFan> <I don't know if an eval factor could include an appeal to the type of position on the board before invoking the tricky subroutine, but it's an interesting thought.> You make a good point about open/closed positions. I guess you could set a global variable such as "OpenPosition = True" after a central pawn capture is made for example. And then that logic could be used along with search depth to determine if "Trick_Eval()", which is more complex, should be executed.

It's been years since I've done any real programming and I miss the creativity behind it.
