So I decided to try out the new opening explorer on lichess and the very first time using it, I arrive at this position
I realize the opening explorer pulls from all lichess games regardless of rating (by default), but I struggle to believe Ng1 was played 12,800 times in that position. Not sure if it's a bug or not. Maybe because black arrived at the position down a tempo?
I think it means that the position reached after Ng1 has occured 12,896 times, but not necessarily from that position. This would make sense if black is down a tempo.
That's really interesting. I suppose it's playing the position rather than playing the moves. I guess it pretty much has to do this to catch transposed games.
Hi. Thanks for reporting this. Here's an explanation:
The number after the move is *not* how many times the moves has been played in the position. It is rather: How many times has the position after the move been reached?
In the game black has lost time, so white can transpose back to a mainline by also losing time.
Both ways of displaying the data (with and without transpositions) have their advantages. I prefer to include transpositions and that's what we did.
@dorhinj1,
@Caustic: Correct. You both beat me to an answer :)
Yes you are right, but to me it is an incorrect behavior: the tool should tell you what was the most played move given a position, not the most common among the reachable..
Basically in this position is suggesting a mistake..
Some opening explorers have an option not to include transpositions, in which case you would just see the moves that had been made in the position you are looking at. This gives you less data, but higher quality data.
I like it, I think it's an excellent tool, you just need to use it with a bit of guile and scepticism. It's actually ace being able to look at openings for variants as well. Talking of which revoof, did you catch my final question on my thread (link below)?
http://en.lichess.org/forum/lichess-feedback/does-the-opening-explorer-include-correspondence-games#6I would have asked a new question, but I don't like cluttering up the forum, so piggybacked it on to my previous thread.
Yeah I can understand that both options are possible, but like malcomar says above, you're essentially suggesting a mistake here. Out of curiosity, is there a good example of a position where retaining transpositional moves adds value?
I would think that the opening explorer can only suggest moves played in a position. The move Ng1 was probably never played by anyone.
