GM Larry Evans' method of static analysis

Sort:
centipawns

Great info, thank you!

blueemu

If you mean: "What is the static analysis for the position?" then it's a straightforward count.

Space: (first count / second count / coordination)

White: 14 / 16 / 2

Black: 11 / 16 / 5

White controls more of the board, but the Black pieces are better coordinated. Roughly equal.

Time:

White: 8 plus the move, Black: 7 (8 if you count the Knight as two moves rather than one).

More-or-less equal in Time.

Force:

Black has two center Pawns against two flank Pawns. Small advantage for Black.

Pawn Structure:

White has a doubled Pawn, but Black has organic weaknesses at b6, d6 and d5 and a slight color-complex weakness on the dark squares on the Q-side and on the light squares in the center. Since he lacks his light-squared Bishop, only the light-square weakness in the center is really significant.

I would evaluate it as "Very slightly better for White"... but then, so is the starting position, before either side has moved. White has not managed to increase his opening edge significantly.

Of course, this whole evaluation can be over-turned if some tactic exists. Static analysis is intended to guide your choice of plan, which in turn should guide your dynamic analysis. It was never intended to REPLACE dynamic analysis.

@knig22, I think Black has more force in that position, he has 2 central pawns against White's 0.

Im I correct in stating that White has a time and space advantage with equal force?

And since the knight on d5 is threatened to be taken, white can best defend the knight with a rook to maintain time advantage?

My off-the-cuff instinct would be to retreat the Knight to e3 rather than guard it on d5, since exchanges are typically in favor of the more cramped side.

@blueemu, at first I was ashamed of not remembering the game, but after Rxe5+ I inmediatly remembered the game! I dont know where you posted it but you said something along the lines of "This is all planned, now my king will hide away"

I agree with you, after Ne3 White can try and buildup on d6 and combine it with a timely f6-push, if White manages to push f6, deflect the bishop from e7 and then take on f6 he should be winning.

Yes, it's worth bearing in mind that it's sometimes safer to hide behind ENEMY Pawns rather than friendly Pawns... your Pawns can be captured. His can't (unless YOU choose to do so).

I think you had all prepared after Nxd5 and those tactics were MAD, a lot of pretty cool mating combinations.

The Gotenberg, I knew it!!! True to your style! I guess you know the history about the Argentinos vs the Soviets? grin.png

OK thanks for the feedback. In my position i would probably consider Nc3 stronger then Ne3 because the knight could then hop to e4 covering the square f6 to support an eventual f6 push as BP suggests. Or am i wrong?

Sounds interesting, I thought keeping the knight on e3 was better because it keeps it near the king, there are some f6-Nf5 ideas in the air, and you can also support f6 with Ng4.

Actually, I didn't even SEE Rxb4 until he played it. The whole Queen-sac / Smothered mate combination was fortuitous.

It's better to be lucky than good!

... and yes, I'm aware of the history of that variation.

Yes Ne4 in combination with rook ad1 covers d6 and f6 at the same time

One problem with heading the Knight to e4 is that Black has had time for some moves, too... and he might be setting up to play d5 in reply.

Another idea (associated with Ne3) is a K-side Pawn storm. If you can keep the center immobilized, you might be able to take advantage of the Pawn on f5 to push g2-g4-g5 followed by N(e3)-g4.

Lol! I remember Kasparov telling it on one of his videos.

Fischer played it tho, with the correct moves!

Mobility and development are (in my view) emergent properties of the more fundamental elements of Space and Time.

Jeeze... I sound like Stephen Hawking!

Thanks for your efforts blueemu and BronsteinPawn! Good thread for improving players

@blueemu, where the heck is that KID game where you miss a discovered attack on a hanging knight, try to complicate things, lost all your kingside pawns and got a naked king, just to completely destroy White? It was a must win situation if I remember.

I was gonna apply Larry Evan's method to kibitz that game, which I already kibitzed, but I cant find the thread where you shared it.

Thanks for the instruction and time put into it!

 You are welcome, we should all give blueemu a christmas gift!

Not sure where the thread went, but this is the game:

... and yes, it was OTB, last round, must-win, playing Black against a higher-rated opponent.

Another game that might be worth doing a STF analysis on is my "cliff-hanger" closed Sicilian:

I also remember that game too!!! Geez, I need to play some games like those before I die.
