raskerino: ... I don't understand how that happened, beautiful. Maybe a computer will help.
But I can do some of the simpler tactics (only of course after moro's played the move). I think 17.a3 has got to be the wrong way to meet ...b5, but ignoring that, let's get to the tactics. 21... e5 is well, crazy? Inviting absurdity? I don't know the right words to describe it.
I have no idea why white didn't choose 23.Bxb4. Though, admittedly, I'd be terrified to take such an offering against moro. Then again, I'd be lucky to last 23 moves. My computer does prefer 23.g6 as played though, where white is supposed to be completely winning.
To show I do see something though, if 25.Bxb4 then Nb3# is quite pretty. I think 24.Qd2 must be wrong, because after displaying it's complete confusion with jumping evaluations, my computer settles on equality here with 25.gxh7+ Kxh7 26.h6, oh, in the time I typed that it decided 25.Na3 gives a slight advantage to white...
Moving on, 25.f5 is a very bad move, and 25... Qa1 a very nice response, of course the rook is still taboo. 26.Qe3 is needed to give the king space (24.Qd2 does look bad in retrospect), and the rook is once again unassailable on b2, due to the continual threats on b3 (27.Bxb2 Nb3+ 28.Qxb3 Bxb3 where the queen can't be won back because of the mate threat on c2).
Sadly, I don't like 27... h6, when 27... Rxc2+! seems so much prettier . 30.Qd2 looks much safer than 30.Nd2. My computer thinks black should play 31.Nb1, so yeah, clear mistake, I believe white's okay after 30.Qd2.
From here, morozovech's are wonderful out of nowhere (I like the placement on g5 and b5, though ...Bxf5 would've made the game a bit easier), it's a delightful game. The rook that stays in danger for so long, yet takes so long to be taken is a great touch. So are the bishops exploding out of passivity. I play different sicilians, so my understanding of these positions is even lower than my normal, but I'd have been terrified of white's pawns from e4 to h4. Instead, morozevich offers up an exchange and blows the game open. Fantastic. What's more, the endgame's nice too.
