arguing with non titled players is like winning the special olympics...
Play in one more event and surprise, we will be in the same boat. But like always, when you have lost the argument, you resort to more logical fallacies. This time, an indirect ad hominem. Trying to see how many you can fit into one discussion?
I'll chime in again and say Caruana has had a reputation for some time as a player who purposely goes into these sorts of positions (the engine says the eval is 0.8 against him, sometimes more) but he chose it because he noticed that intuitively good moves for his opponent are actually bad, and his opponents are unlikely to check this line deeply, because the engine says it's good for them.
Caruana also pointed out in an interview that all positions, when you prepare and analyze deeply enough, either end up as a draw or a win. So in that sense 0.8 doesn't actually mean anything bad if it's going to end up at 0.00, it's just a warning sign. In a real game, as long as you have an idea to leverage, and know where the pieces belong, you're going to do just fine.
And I've seen this for myself. One time I was trying to refute some position my opponent kept playing into, but as is typical of structures with pawns on d5 and e4, the engine was saying I had an advantage that didn't actually exist. You go 15 moves into it and the engine says oops, my bad, it's just 0.3 not 0.8... and since your hash isn't large enough, it wont remember that. It will send you down some rabbit hole of "oh this other line is 0.8, this time for sure..." but nope, it's not. The engine will never figure this out from the initial position. You always have to put more moves on the board to get a proper eval.
In the end it's better to play something that has ideas you understand and are excited about trying to leverage for a win than it is to chase some engine eval.
1000% this. You nailed it in the head my friend
1. its not always about the eval on its own, but the likelyhood your opponent has the skill or know how to materialize and mantain it.
2. at the end, a line is busted or its not, the rest is how problematic it is to play. Many things that are playable are almost never seen not because they are bad but because alternatives are preferred. (e.g the old steinitz defense of the ruy lopez went from being an opening played by world champions to almost never played despite having no refutation
3. what problem is too large once you establish a line is not busted can vary between players. the pirc at the super GM level for example is a sound defense, but white has so many ways to claim a pleasant edge the consensus is that most players find it requires too many small problems to solve for most players to want to play it Something similar has been happening with the KID. You also have to balance what problems what you play creates for you with what problems you create for your opponent. Rapport for example sometimes plays openings that are outright refuted but he has confidence the odds you happen to remember how so when are small.
"The engine will never figure this out from the initial position. You always have to put more moves on the board to get a proper eval. ."
this is how i know llama knows how to use an engine. The horizon of the engine must be compensated by a human pruning the position deeper manually to get a true evaluation. leaving your engine on till depth 50 is in some positions misleading. This makes preparing agaisnt such clowns a breeze.
the truth of the owens is , most players are not willing to deal with the set of problems/challenges the defense throws at you. many players hate closed positions, others hate having to figure out subtle differences in each position (when to play for ba6 vs queenside clamp ,when g5 work when nb4 works, when castling is good vs bad the few times f6 is good etc) others hate that the resources to find out at rare and spread out unlike mainlines were the answer to all their problems can be found in one place (most players dont like being opening pioneers). And that's ok. Its when people think their preferences amount to some objective deficiency in those that advocate the road less taken that i get irked. Especially since ALWAYS welcome analyzing concrete lines they think are refutations or too troublesome but they almost never engage.
