Annotated chess game

So nice of you

now a day game knot have more annotated game on London system.

But there are openings that you like - because you feel comfortable playing them, you like the sort of game you get from them, or they suit your style. About 45 years ago I had a particular fondness for the Nimzo-Indian/Queen's Indian systems. There was something aesthetically pleasing about them. But I had abysmal results with them. No luck at all. Eventually I made the switch to the King's Indian/Modern Benoni types of defence. I was forced to conclude the Nimzo simply didn't suit my style of play.

No I had researched him on the Internet

The impression I get with the London System is that Black has to beware of getting squashed, or finding himself in a passive position, unable to undertake anything positive. So an early strike seems to be indicated.

but no good player sacrifice his king side safety by h2-h4 unless he looked some mating net

A good player will if it seizes the initiative and throws the opponent onto the defensive... even if he DOESN'T castle Q-side. But the position seems to be the wrong 'shape' for such an attack to be promising here.

you are very good in prediction

I don't know that I'd go so far as to say h4 is completely ruled out, but you have given white a lot more to consider.

Was there anything against Bd3?

well on d3 it is rather biting on granite on g6, and also after I get in e7-e5 I am going to be threatening e5-e6 forking bishop and knight.

I assume Charles' typo and I agree e5-e4 was likely the reason for Be2 rather than Bd3

Is it necessary yet?

I was rather expecting him to castle first. It doesn't make much difference

It is necessary unless white really likes variations like 6.c4 Nh5 7.Bg3 Nxg3 for example

The c2-c4 seems to have been called for for a bit of a while, now. I might have chosen c2-c3 a bit earlier, as a species of Colle System with the dark-square bishop OUTSIDE the centre line of pawns. Mind you, the bishop so placed removes the necessity (I should have thought) to forcing through e3-e4, which suggests that c2-c4 was the more energetic option.

Archduke piccolo's idea is sound, but I suspect the reason to avoid c3 and play c4 is just to give the b1 N a better square to occupy on c3.

I'm not sure I agree with you there, Joe - the line you suggest seems to have a whole different shape to it.

It doesn't force it, but it does offer it soon

9...e4 looks tempting, but Black can't close the centre properly on account of the unprotected pawn at c7.

The exchange is OK, neither great nor bad. It does ease the center situation a bit. Not a bad thing for black.

I would have preferred ...Nxd2, but I also would have preferred not to have played ...Ne4(!) Does White exchange on e4 now...?

you've added complexity to the game here when your previous move seemed to be aimed at simplification, or is this sequence a clever deception aimed at your opponent?
