Resignation Trap: <This time he gets close to Stein>.
How much did he drink from the Stein?
Here are some notes from the tournament book:
8. Be2
8. Nxh5 allows 8...Bg4 9. Be2 Bxe2 10. Qxe2 Qh4 11. Ng3 Nd4 and Black is better.
9...Be6?
A blunder. 9...a6! was the only move.
12. Nxa7
A move admired by all, but unnecessary. 12. Qa4! should win in all variations.
15. Qxh8
This material grab is not the best. After 15. Nf6+ Ke7 16. f5! White has a strong attack, threatening, above all, 17. Bg5
16. f5
In order to open the diagonal leading to h6.
17...Rxc4!!
After 17...Bd7 18. b3 and Black stands poorly. After White castles (not immediately Bh6 due to ...Qh4+), the threats of Bh6 and Re1 force Black to return the Bishop.
21. Bf4?
Not 21. Bh6 Qd6+! But 21. Bf4 is not the best, either. White should try 21. exf7+ Kxf7 22. Qh5+ Kg7! 23. Qg5+ Kh8 with a draw. It would be hazardous to try for more, for example, 23. Qxf5? Bd6+ 24. Kh4 Be7+ 25. Kg3 (25. Kh5 Qd6 wins. 25. Bg5 Qh6+) Qc7+ 26. Kf2 (Or 26. Bf4 Rxf4 27. Qxf4 Bd6) Qc2+ 27. Kg3 Qd3+ 28. Kf2 Bc5+ followed by mate. Or 23. Qg5+ Kh8 24. Qxf5? Bd6+ 25. Kh4 Be7+ 26. Kh5 (If 26. Kg3 Qc7+) Qd4 and wins.
25. Kxf4
If 25. Rxf4 Qe1+ 26. Rf2 f4+!
