Stoyko exercises

Stoyko exercises is part of my training regime. Here in this thread I will post a few positions that might be interesting (I am yet to study them myself):

I intended to present the position after 19. ... bxc3 and analyze from there but the diagram got weird in some way. It does not really matter where you start.

One challenge using the exercise is to collect good positions without memorizing the game move. That info would bias your own analysis.

Shirov is a  killer ... it looks to me like white has an advantage here with pressure on the f file ... but black does have something going on ... bc looks forced to me, then maybe Rb2 is the only continuation I can see ... but I am a fish, heh.

We are all fish to someone!
