You see it all the time here. Someone wil lask "What opening should i play?" The responses are all over the map. No one looks at the OP's games. They just spew out the openings they play, and or are "agressive" without a bit of any analysis to back up there post.
Yeah, and usually the questions themselves are malformed. I.e. "what's the best aggressive opening?" But they don't even know what they're asking. So sometimes someone who gives an answer totally unrelated to the question happens to answer what the OP had been attempting to ask in the first place.
Like "I like to attack with knights because they're tricky" and the OP, who was asking for an opening, says "thank you so much, I saw openings with early bishop moves, but I didn't understand, now I will move my knights instead!"
heh.
I'd never heard of de la Maza before and just took a quick look at his book on amazon. What I gather is he tells weak (class E-C or so) players to focus on tactics and work hard on training and improving their tactical vision, more than other parts of the game. Honestly, for that level, that sounds reasonable. You can probably go all the way to Class A or even Expert just by avoiding making blunders and punishing your opponent's blunders. You need to know some basic openings (so you get a decent position to work with) and basic endgame technique (K+whatever vs K checkmates, how to convert an extra piece or exchange in the endgame, how to win a pawn-up pawn endgame...), but beyond that, tactics decide most games at that level.
What's annoying though is his book can be summed up into 1 page. The rest is just cheer leading. He gives no tactics in the book, and doesn't even provide suggestions for other tactic collections out there.
Also annoying is that he sells it like some genius insight when any coach (or experienced player) in the last 100 years would tell you the same thing i.e. tactics are very important, and one of the best ways to improve when you're new.
