Moving Along, more annoying problems
The current problem, for reference, is Advanced100-1.pgn #20. The tags are as follows:
[FEN "1r6/4kp2/3n2p1/2KPp3/4P2p/2NR2P1/7P/8 b - - 0 1"]
I scored 10% on this problem twice in a row, which is no good. For a quick understanding of my scoring system, there are four positions that you need to solve in this problem, according to the PGN. With these four positions, Imagine on the first move, you do not get it correct (3 guesses, all wrong). The next move, you do the same (3 guesses all wrong). On the next move, you guess it correct on the first try (1 guess, correct). Finally, on the last move, you guess wrong on all three guesses (3 guesses, all wrong).
Thus, my program would do this math:
First, number of correct answers:
0 + 0 + 1 + 0 = 1
Divided by number of guesses
3 + 3 + 1 + 3 = 10
which is 10% correct. Now, here's where it's really uncool, and it really hurts your score. If you have a problem next with three positions, and you get it right on every try on the first shot, getting 100%, your new overall score is not 55%. It is actually 30%, because each problem is weighted by the number of guesses. Therefore, the previous problem, with 10 guesses is weighted more heavily than the current problem, with 3 guesses.
Thus, it allows one to take their results table with a grain of salt, after understanding the weighting mechanism.
Moving on to advanced problems
I'm off to a decent start, after finishing my last Initiate problem set last night. It got rather ugly and I'm disheartened by the apparent lack of growth, but having a solid mathematical background, I realize that my program's scoring system will show lack of growth when things are infact OK. My current problem shown above (Advanced 100 #1, Problem #3) has the following tags:
[Black "Van Wely"]
[FEN "8/8/5rpR/3r4/5P1B/5k1K/7P/8 b - - 0 1"]
[White "van der Wiel"]
For future reference and whatever else you might want to do with it. It isn't until a few moves deep where it becomes a challenge. This is Black to win, not black to draw (although the position looks quite drawish.
I am going to cease my coding work until later. I already have written several reports in my system, including problem detail (most useful after you have finished multiple runs on a problem). I also might release some stuff in CSV format later so that it is possible for the user to build reports and graphs based on their results, but I'll probably do that after I finish my circles. If there are certain items that you want to be included in the report (based on what I am storing) then please feel free to ask. I do not store any time information, unfortunately, although that might be acceptable in a future release.
Either way, enjoy, and I'll keep working on finishing these circles up.
Added Results and Annoying Problem of the Day
The stuff that I have added above will make it so that I don't have to copy and paste that table ever again!!! That is linked directly to my Tools Site, where the program itself resides. The other item is the annoying problem of the day. With the one displaying today (Initiate100-4.pgn, problem #17), it is not the first move that got me, but instead some of the later moves, after the black response. I will have to post the response to the comments later.
Hopefully these two items might make my blog more interesting. Because they are automatically updated, it makes it so that information about where I am does not require my input.
I didn't expect growth on the two that I did twice last time - the goal is not memorization but recognition, and trying to do them twice in a row defeats that purpose. I hope for improvement on the later problems, but we'll see.
I played in Delaware today. It's amazing, the two strongest people there I beat today, and two of the weakest I lost to, both by giving away mate in one's!!! I have a long way to go, clearly.
Submit PGN's for my APP
I have seen two people join up for my application, and responses have been positive, which is good. Now, I have something like 1,400 problems in the system, and another 2,100 at home that I could add, but I think the current sets reach a high enough difficulty.
That being said, if anyone has a good set of problems that are not necessarily tactical - mate in one problems or mate in two problems - or any other type of problem that could be interesting, such as positional with notes - in PGN format (chessbase can do output in PGN format) - then I would be glad to add those into the system (which can be easily done, because all of the problems are PGN based) and there would be more goods for people to enjoy.
If this sounds interesting to you, please let me know.
I'm done with Football
There is a reason I love chess. There are only, really, two people involved (of course, when you deal with the championship, you can deal with the crazy K if you want, but that's another story). There is not an official that can walk up and say 'you didn't advance that pawn properly, two file penalty, opponents move' on you.
Given that there are situations where you will see people who touch the wrong piece, or other rather obscure time problems, that is different, its solid, its in the rulebook, and we all stand equal.
But last night, even Steelers fans that I watched the game with had to admit that the officiating calls were heavily against Seattle. I can't blame Seattle for being disheartened in the second half, although they played their hearts out, and I believe that they completely outplayed the Steelers.
I want you to imagine that an official walks up to your board in the middle of a heated game were you have worked to double your rooks on an open file, and suddenly he says 'you shouldn't have this rook, it was moved illegally' when everyone in the room can see that is not the case. He removes it from the board. Can you imagine your frustration?
That is why, I will never watch football again. When I play chess, and I lose, it is because I suck, and not because there is a third player in the game. I feel bad for the Seattle players and fans (being from the PacNW, I've been a fan since childhood). I feel even worse for Bettis, though, who will have only one Superbowl Ring, and it will be XL, the game that will hopefully be the catalyst for change in the way that American Football is officiated.
Lots of Problems + Lots of Games = Not Good
I did a ton of problems yesterday (~60), then played a lot of chess after about an hour of break - and I found myself tired and unable to concentrate. This has to be like trying to compete in a marathon after doing a few hours of weight training. The goal must be to build up the muscle and stamina FIRST, then see results LATER. Last night was not a good night.
I haven't got much else to say today. Still cracking on the programs. Due to regular lack of time, I've been adding the number of nights that I spend at chess club (1 a week) to the number of days I have per circle. So, instead of 32 days for this circle, it will probably be closer to 36.
