    I am black again, another dodgy sacrifice by me on move 10. It didn't lead to a win this time, but I did end up with the better endgame position, I just didn't have the ability to convert it. I guess I'm very lucky that my opponents are human and not computer.

    Does anybody disagree with my comments? I'm looking for advice on how to study my games.

    Just keep playing how you are playing. You will have to lose
    some of these dodgy sacs to cure you!
    You can squeeze some play from that ending. The h3 pawn gets you play.

    7.c3
    "I don't know if this is opening theory. Probably the London system or something like that, but it looks bad to me. It removes a natural developing square for the knight and with h3 having been played as well, I fail to see what it achieves in return for handing me a lead in development".
    I play the London system a lot.My knight always goes to D2 to stop the black knight advance and c3 also shores up the position against a queens side assault by black

    I disagree with your assessments of white's seventh and eighth moves. 7. c3 is fine, it leaves your g7 bishop biting on granite and generally helps to stabilize the centre, the knight can go to d2. Personally I'd have castled instead of playing 8. e3-e4 but I don't think his move is as bad as you seemed to think. 8. ... e5 is clearly the right thing to do. He is probably wrong to play 9. dxe5 and should just move the bishop to g5, pinning the knight.

    Your sacrifice wasn't sound, but your self-criticism is too strong. In a recent game (Game 10669692) I went for the Greek gift sacrifice, only I'd failed to spot a possible defence and so lost. I saw the defence shortly after committing myself to the sacrifice. If you look at the books after 8. Bxh7 Kxh7 9. Ng5 they point out that the better defence is often to move the king to g6 rather than g8. So I'd spent more time on looking at lines after 9. ... Kg6. I don't think this completely explains my missing the move, but my underestimation of 9. ... Kg8 created this cognitive bias in favour of a duff move.

    In my opinion the London System does not work well against black defences involving d6 and e5. In particular the bishop on d3 and knight on f3 are prone to a pawn fork. I think White is better off playing an early Nc3 and turning it into some sort of "150 attack" or "Barry attack" type set-up.

    Can you expand on that? I never heard of either attack.

    Yes that fork is one I've fallen for before but I watch out for it now.
    There's ways to combat it.
