Title: Analysis Requests
Post by: Dr. Egregious on November 17, 2013, 02:45:19 am
As I mentioned before, I thought it might be fun and informative if I started this thread, and my workload has finally cleared up to allow it; if you've finished with a game and you'd like some advice and constructive criticism move by move, feel free to copy/paste your PGN here, and I'll try to have it done within twenty-four hours.  If you just want feedback on a few particular moves, I can do that in short order.   :)

SHANE vs TAYLOR
01. e4 g5
02. Nh3 f6
03. Bb5 Nh6
04. d4 c6
05. O-O g4
06. Qxg4 f5
07. Ng5 f4
08. Qh5+ Nf7
09. Nxf7 Qa5
10. Nd6+ Kd8
11. Qe8+ Kc7
12. Qxc8+ Kxd6
13. e5+ Kd5
14. Nc3+ Ke6
15. Bc4+ Kf5
16. g4+ fxg3 e.p.
17. fxg3+ Kg6
18. Bd3+ Kg7
19. Rf4 kg8
20. Qxf8++


I already know about the first part where I deliberately wanted Shane to win via a Fool's Mate on Black's side.
At some point a game of "Tag" appeared to start; the King was running for his life most of the time :))

Was there anything I missed, after post 9459 when Shane wrote a wall of text (http://shanescavestory.createaforum.com/chess-archives/preliminary-chess-round-shane-vs-taylor/msg9459/#msg9459)?

There was an error in your notation on turn 16.

Pawns can't just magically jump to the same row as the opposing team's starting row. :P ~ KarjamP

This post (http://shanescavestory.createaforum.com/chess-archives/preliminary-chess-round-shane-vs-taylor/msg10003/#msg10003) and this post (http://shanescavestory.createaforum.com/chess-archives/preliminary-chess-round-shane-vs-taylor/msg10017/#msg10017) should probably help out. Taylor invoked En Passant (http://en.wikipedia.org/wiki/En_passant), so Taylor's f4 Pawn could capture a pawn on g4 and move to g3.

... Right?

I had figured out the problem and actually fixed it: The notation said that Taylor's pawn moved two steps forward to en passant instead of one step: an invalid move.

Ergo, Shane slipped up, not me. :P
The notation was a copy/paste from our match after he won.

Apologies, Taylor; I suppose somehow I never noticed that you and Shane had called for an opinion in that game.  XD  Didn't mean to ignore you.

Anyway.  I'd say 10. ... Qa5 was the best option you had, because it didn't result in instant death and it saved your queen.  Shane missed one thing in his analysis, though; had you played 9. ... Bh6, the best counter would've been 10. Nxh6+ Kf8 (forced) 11. Qf7#.

10-11: There's not much to say; you only had one possible move each time.

13: 13. ... Ke6 might've been better, because there are still plenty of threatening pieces left on the board and d5 isn't really a safe place for a king until you're mostly down to pawns and a rook or two.

16. Props for remembering en passant in the heat of the moment, but I would've just played 16. Kxg5 instead.  That way your pawn wouldn't be left open to recapture by two of Shane's pawns.

19. Rather than 19. ... Kg8, you needed to leave g8 open so that your rook could protect your bishop and prevent Qxf8#.  You needed to get your queen into play to stand a chance, really, and the quickest way I'm seeing is e6, Qb4, Qe7.

You didn't miss much, after Move 10; there's only so much you can do when your opponent can keep putting you in check and you've only got one or two ways to escape.

No worries. :)

Not to mention he missed Qa5 as well :))
Guess that's what happens if you don't have a physical chessboard and have to resort to a mind-one.

10-11: There's not much to say; you only had one possible move each time.

13: 13. ... Ke6 might've been better, because there are still plenty of threatening pieces left on the board and d5 isn't really a safe place for a king until you're mostly down to pawns and a rook or two.
I see...

16. Props for remembering en passant in the heat of the moment, but I would've just played 16. Kxg5 instead.  That way your pawn wouldn't be left open to recapture by two of Shane's pawns.
I hadn't seen Shane's rook on g1; I thought he'd move his Bishop to d3.
I kinda like en passant, and I especially like matches with eight of them. :3

19. Rather than 19. ... Kg8, you needed to leave g8 open so that your rook could protect your bishop and prevent Qxf8#.  You needed to get your queen into play to stand a chance, really, and the quickest way I'm seeing is e6, Qb4, Qe7.

I see...

Thank you very much, Dr. Egregious! :)

Wait, eight en passants? :o


EDIT:
Thread stickied; I believe such a thread is important. :)

You're most welcome.   :)

Eight en passant captures?  I've never seen more than one per game in practice; eight in one game is possible, but you'd basically have to be working together with your opponent to make it happen.  Eight is also the absolute maximum that can happen, since any en passant capture will either remove one of your pawns or move one of your pawns to the sixth rank, where it can no longer capture en passant.

That was against me; someone at these forums were wondering how many en passants were possible in one game.
I think it was Shane, I'm not sure, though. :)
