Amazing saving

It's interesting to watch old games and old (no-engine) analysis. Highly evaluating everything, that players and annotators did, I strongly recommend to check out sharp lines from there. (first yourself and then with engine).
This position could happen in the Krogius-Stein, 1960. White king is in a big danger, and annotators even didn't try to look for a defence here. But White is better here! Try to find the engine's way!
