Great blog!
Here is a study I made about it: https://lichess.org/study/SlvkNXhG
As a common Sicilian player, I put the Grand Prix as a priority to study, and figured out really fast that black must break the center ASAP with e6-d5 (with e6 being absolutely crucial, as you could see in the example game the IM neglected that), no lagging behind, no passive moves, or its all over. Usually I can hold my own against this now as Black, even winning in positions where I refute the sacrifices of a frustrated white. However, it's not to go without mention that if I do play passive, white literally devours me. Two years and I'm still worried over the same problem!
After Nge7 play the prophylactic move Bb3 then after 0-0 d3 then d6 then continue your previous Qe1 Qh4 plan then Ng5 and then throw all your pieces at your opponents king.
1500 KG player here, loved this so much, the attacking ideas feel very natural to me, and I'm very interested in the ...d5 analysis. That move tends to be my goal when playing the Sicilian as black and in my initial poking around with the analysis board I can't find how white stays with the Bc4 and Qe1-h4 ideas in the face of black immediately focusing on the ...d5 push
Been playing this for years, but I always get confused about one thing. Some guides say to always play the bishop to b5, not c4 (especially when black goes for e6) and trade it off for knight or bishop. Often the black knight then his to the centre. Which square is best?
can you disclose your identity IM doughnut ? do you have a youtube channel ? do you play OTB, can you show some in real life games ofyours with Grand Prix Attack ?
