Lemming vs Movei 0-1 (Game 11)

15. h4? No point in launching the premature attack, especially when Black has stronghold on Kingside with Fianchetto Bishop, well positioned pawns and all that, White still do not have any major pieces on the King side.

(KeyWord: Premature attack without any pieces on king side)

Hint: Play positionally and normally with the good development on the Queen side.

23. Rab1? Looks weak. Moving the next major piece just to protect the pawn? especially when there are better alternatives? Should play actively and look to control more squares.

(KeyWord: Piece Activity)

Hint: Nb4 then Bc3.


29. Nd5 is a lot better, positionally. Knight outpost in the center.

(KeyWord: Outpost)

30. Ba5?? Chasing the opponents pieces without any additional plan is not too good.

Hint: b3 preventing the queen pawns from advancing, and creating the stronghold there.

(KeyWord: Pawn structure Preventing the opponent from creating good pawn passers)

32. Qe1?? After Bishop trading, Black will play f5, undermines the white's center pawns and creates weakness in surrounding areas.

Hint: play f4.

(KeyWord: Developing good pawn structures, Prevent Opponent from undermining your center pawns)

Good stuff Swami. I hope to make a minor testbed out of Lemming errors that you report to help guide some minor eval surgery. If there are positions where Lemming does a particularly good positional move try to report some of those as well, so I don't tune things so that they fix the problems you identify at the expense of ruining the things it does well.


I understand such things are sometimes harder to identify.

Ok, Next time I'll try to report that as well. Actually It's not at all hard, I will try to finish commenting the rest of the games in 3 days time.

From memory, Sam is either IM strength or close to it.

Not that close. I played a little online during my break from computer chess, and according to ICC I am maybe about Telepath level. Anyway, its nice to have someone else go through and provide some perspective, which Swami has been kind enough to do. Its not that easy to find master level folks willing to volunteer their time like that and it frees up my time to code instead.

Yes - Swami does a great job with such analysis. Engine authors are very lucky that he provides such useful hints. Well done Swami.

Sorry about the double post. When I try to delete one, they both disappear!

Thanks, Graham. It's quite a fun thing to do, I hope to get more of these from other prospective authors interested in active development and looking for a serious competition in ratings lists, So far I have TwistedLogic, ZCT and Lemming in my list.

Romi vs Lemming (Game 13)

Errors:

13...Rc8?? This semi open file is not much of an help.
This move is without plan and positionally inferior.

Hint: Rd8! the move facing the Queen file where there is a pawn.

(Keyword Unnecessary Rook move)


19. h6?? Why a single forward when it is possible to push the pawn more ahead and minimise the number of moves needed to set up the whole pieces.

Hint: h5 or Rd7
(KeyWord: Limiting the mobility of pawns Itself)

Good moves:

11...Qa6: understands how to limit the mobility of pieces.Queen is kept in a Square that prevents the white king from castling.

(KeyWord:Limiting the mobility of pieces)
