Is chess the Only 100% skill based game?

lol

Moreover, I can statistically prove you that poker is just like loto a skill based game, in the loto game I've been used to play in approximately 2% of drawings all the extracted numbers will be even or odd, meaning you are increasing your chances of winning significantly when they come out all even or odd.

Well, you have Starcraft. Also, you have Bridge, althought there is estimated 10% luck (even though it feels far more)

Does the game of Snap count?

Chess really is 99% hard work and 1% talent

Why does everybody think chess is 100 % skill based ?

if it was the player with higher skill would never ever loose to a player with skill that is a fraction lower.

The scores would then look like : within 100 elo range the games will always be remise ( I took 100 as an example not knowing the right number ) more elo difference would always result in a win for the highest ranked player. ( assuming both players are at the elo matching their skill ).

Why is this not the case ?

In reality when playing chess we have to choose between moves that we cannot calculate until the end, therefore we look towards "signs" that might indicate candidate moves and we add some ( pathetic ?? lol  ) calculation to that, if we are lucky we choose for the move that brings the best winning chances, if we are unlucky that game we go for the wrong one.

both players have enough skill to avoid the worst moves but none of them can find systematically the best move, this results into a situation where the winner is the most lucky player, that is when both players are equally skilled, if this is not the case the more skilled player will be able to rule out the moves the less skilled player does not avoid, and the more skilled player has a better luck / skill ratio and has more probability to win. 

Very good explanation. Randomness and luck definitely play their role in chess.

A perfect poker playing machine would still lose occasionally. A perfect chess playing machine would never lose.

Since humans aren't perfect (and even the best engines aren't perfect yet), there are still wins and losses.

Chess isn't to blame for our frailties.

hmm

lets take a lotto game with 6 numbers to be drawn.

first number may be even or odd, both are ok.

second number must be the same as the first, even or odd = 0.5 probability

third number must be the same = 0.5 having both = 0.25 probability

fourth number : 0.25 * 0.5 = 0.125

fifth number = 0.5 * 0.125 = 0.06125

sixth number : 0.5 * 0.6125 = 0.30625. or around 3 % close enough to your 2 %.

to beat a system you need to find a game where the odds and the rewards ore not in line, this means that if you play  the even numbers only and they come out at an unexpected frequency AND the lottery pays an unexpected amount of money then you can win systematically.

Mabye one needs to define what is "luck" and what is "skill". There are for exampel World Championships in "rock, scissor, paper". And to you whom says it's bullshit and only luck, well, there are a big psyckological factor which desides who wins. Ofc, you need to be "lucky" aswell, there are always luck incorporated in everything we do.

Well I think only Chess and Pool/Billiards.

Does anyone know of any other 100% skill-based games? Please list them here.

chess is not skill based..oftentimes it is decided by PURE luck and only luck...nothing else.

_______

Please provide an example of a chess position that was won/lost by "pure luck ... nothing else."

Monopoly, bridge, craps, hop scotch.

When I play chess, I'm lucky because my strength is anywhere from 1000 to 2000. Just look at my highest and lowest blitz rating on here. I believe it's from high 1100s to mid 1500s

When I am lucky my opponent plays into the kinds of position where I am most skilled. At my level the skills is not evenly distributed.

No! If challenge become 50% skill and luck if same rated.

What? 

The break-off in many pool variants is rather random, e.g. 9-ball. Billiards games are mainly skill but certainly not completely.

Non-exhaustive list of luck in chess:

> Who you are drawn to play, and with which colour

> Opponent blunders for no reason

> A lot of moves are not humanly possible to evaluate to a clear conclusion. Which way the coin falls on an 'unclear' assessment is basically a matter of luck. The skill is in balancing out the various factors in play and making a judgement call - the better the player, the more likely the judgement to be correct, but even very strong players can be unlucky.

> External factors beyond your control, e.g. poor playing conditions, noise etc

> What happens in a mad time scramble when both players are moving very quickly to meet the time control is largely luck

As for the "lick element" referenced in post #201 however, I'm not sure what kind of chess you're playing...

Poker is NOT skill-based at all. It's just whether you have a good have a good hand or not and making decisions. It is 95% luck and 5% skill. 

If you believe that, you're probably not very good at poker. 

I'm not much of a poker player, but there is quite a bit of skill involved. Part of it is the ability to work out the odds of a given hand winning based on the cards that have been played. Part of it is knowing how to manage your chips, and part of it is being able to read your opponents. Those are all skills that can be learned, and a player who has mastered those skills will beat an unskilled poker player almost every time. 

Yes, there is luck in poker, but there's also quite a bit of skill, which explains why the same people keep winning. They're good at the game!
