Hi,
Going through the early part of the game with different engines plus my own brain, I think the writeing was on the wall from move 17.Bxd4 Giving up the dark squared bishop just seems wrong at least to my eyes, maybe Nd1 is better and which is a theme in the closed sicilian .... Before this though 5.h3 I assume you are trying to play a reversed opening and make use of the extra tempo, but! is the tempo any good? .. In my own book I even have 7.Nge2 in
red and with a
? after it .... 14.g5?! releasing the tention does not feel right, in many of the games I know and have played even if you try to penetrate down the h file the king can run away via f7 and whites king tends to be draftier anyway. 15.h4 also seems to slow and blacks counter play seems far more dangerous and is easier to play.
The first new move in my database is 13... Bd7, others have gone with 13...b5 but Bd7 seems stronger
