How Good is Good?

Submitted by farbror on Mon, 06/08/2009 at 9:45pm.

I use three different sites for tactics training and those sites give me quite different estimates of my tactics skills (approximately 1300, 1500 and 1700 at the moment). Ratings are just ratings but as a professional statistician almost any number has some sex appeal. Still, I like to know a little more about my tactics skills.

IM Jesper Hall is suggesting in his excellent book on chess improvement, "Chess Training for Budding Champions", that improving players should keep a notebook with interesting chess stuff and never forget to have fun while training.

 

In a recent slow game I found myself in the following position (nb: white to make move 18) that made it into my notebook for several reasons. The position gave me a clearer picture of my strength and weakness as an OTB player. My spider senses went all crazy and I was almost sure that 18. Nh5+ was the proper move. I spent a fair amount of time trying to check the calculations but I could not convince myself that the move was sound. The good thing is that I found the move and perhaps even that I decided against the move when I failed to make sure that it was sound. The bad thing is that the move I did make swept away all my edge in the game.

So, my positional evaluation (amongst other things) are bad but my spidersense for tactics is OK. The nagging question is: "How Good?"

Or more precisely: "How strong would a player have to be to find this move most of the time?" What do you think? I asked the question to a very strong player who kindly offered his view of things.

 

The fact that I almost found this move OTB is a small highlight of my Chess Life and maybe an indication of the fact that my tactics training is paying off. My GM friend suggested that the Nh5+ move might be of, say, "2250-quality" which of course made my day. Surely a confidence boosting entry into my chess notebook! I am not there yet but there might be a possibility to reach 2000+ a few years down the road.

jlueke - White can play Nf6 and will mate shortly by targeting h7 with the queen also. Whites pieces are so active they can overpower any sort of defense black can try.

jlueke - Doing Nf6 immediately after Kh8 is much better, in fact, it's pretty much winning - Black is forced to give up the exchange to avoid the threat of Qh6 and Qh7#

and Kg7 doesn't help matters much, Qg5 has a lot of threats, most notably.... Nh5+!

Why does black have to take the knight?  What is wrong with Kh8?

I find it nice to read comments on chess tactics from the players. Reading those comments have helped me understand my game much better; and the subject of chess.  Example, if i don't read my book "The chess bible" i can always read the comments of other players on chess.com. It is somewhat hard for me to understand all of the opening lines, often written and used, but i do have some understanding of them. Yet, i have come to enjoy the chess players comments.  Thanks a lot guys and girls!

My correspondence rating floats in the 2100's (with tactics being my strong point) and I did in fact find it instantly. The fact that you considered it is probably a good sign of potential... but ultimately the calculations should have been rather simple (with all due respect :P) ... any position where there is a series of potential checks lessens the number of individual moves to look at.

With time all this will come together.  Keep practicing and you may become quite proficcient :).

I wonder why th move 20. Qg5 is better than the move 20. Qh6.

here are some variations to think about.

Interestingly, I did not see Nh5+ immediately (probably because I read the words before I looked at the board =D), but I saw Rf6 almost immediately. Am I just drunk to have that happen? In any case, Nh5+ is definitely a good find. If not captured, Qh6 ends the game in any case.

Good chessy blog - one of the few blogs I've ever commented on, in fact. I guess I'll have to back to practicing my tactics - I've only done 6 Tactics Trainer problems on chess.com and have only practice tactics from one chess book. That's my only training over the past year. =D Geez, I'm even lazy in chess...

Good luck getting to the top - hopefully, I'll meet you there! =D

Obviously coming from me this does not mean much, but when I see 5 pieces (Q,N,B,R,R) brought to bear on the kingside vs 3 defenders (Q,B,R) I am not going to worry about a lot of calculating if I can open the g-file quickly.  If you hesitate, your opponent will have time to mobilize the knight and fortify his defense.  Nxe6 does nothing to break up the kings position. 

Great work in getting so much artillery to the battlefield in only 17 moves - Morphy would be proud.  (He would have sac'd the N too, lol!)

I also think the advice given here is sound...Nh5 + definitely works, and the follow-up of Rf6 was outstanding.

I understand Arunchess's point, even if the delivery is a little offputting.  Personally I believe his points, if well understood, do improve tactical vision, but I think it is also not the entire game, and some calculation really does have to be made as there are too many tactical rejoinders available in real games against resourceful defenders to ignore the possibilities and rely solely on the principles he enunciates.

I'm sorry but Nh5+ is quite natural and very easy to calculate since black is forced to take it with the pawn...

On what sites did you make those test where they evaluate your skills? How much did you pay for that?

I think Nh5 is most natural move in this position. Whether black takes or leaves it, he is lost. Why is ne got confused because he is not trained properly. If you follow rule of thumb ( which everyone who attended proper chess training knows ) You can sack a piece ( or two , or any number ) on h7,g7,etc  provided you can get your queen there with at least one support if opponent has no support.

 In this case black has Queen and bishop who can help. But white can feed two rooks and bishop to help queen. White has 3 pieces to support queen against 2 possible deffenders. Or you can say after sacrifice white has atleast one extra piece to support queen which is sufficient.

If for some reason you can not check-mate you will always get draw !!

Don't spend too much time in long calculation. Just follow above rule of thumb and you will find win.

Nh5+ is a surprisingly good move because it attacks the king while opening up the f-file. White is in deep trouble after the move and is probably better off not taking the knight because that will open up the g-file.

 

Click on the "moves tab" in the diagram and you will see some of the analysis.

Could someone please explain to me how Nh5+ would be a good move?

Tactics rock! =) It's the reason why most of us play chess in the first place!=) Great blog entry!

My trick is: always go with the first move you think of. It seems that nowadays the longer I spend thinking about my move the more likely the mistake.

gxh5 looks really risky when analyzing the game in the comfort of your chess study! It was the only variation I looked at OTB but now I think a "safe" Kh8 is better. Agreed, Rf6 is an amazing move.

:) Thanks for sharing it Farbror .. . All the best to you! Am also sailing in a similar boat although a much smaller one probably. Many a time am also able to work out the 'find the best move' stuff. Just need to get it regularly in OTB games.
