two quiz questions and a game

1. Otto Schatz - Gabriella. How should black get out of check, 28...Qf8 or 28..Kh7?

2. Keith Leary is white. What should he have played?

Shawn Swindell - Jaja Nyamekye

1. e4 c5
2. Nf3 d6
3. Bb5+ Bd7
4. Bxd7+ Qxd7
5. c4 Nc6
6. O-O Nf6
7. Nc3 e6
8. d4

9. Nxd4 Be7
10. Be3 Nxd4? no reason for this concession. Black should just castle.
11. Bxd4 Shawn should definitely take with the queen, but he thought black could answer 11... Ng4, which loses to 12. Qxg7.
11... Qc6
12. Qe2 Shawn said he originally intended 12. Qd3, but came to think 12. Qe2 was better. He was wrong, not because of
12... O-O? but because after 12... e5! 13. Be3, his e pawn hangs: Nxe4. Now white gets some compensation after 14. Nd5 Nf6 15. Nxe7 Kxe7, but not enough.
13. f4 Nd7
14. Rad1 a6

what should white play?

Shawn Swindell, author of this beautiful game.
Shawn played
15. Rd3 but it's also possible to try 15. Nd5!?

If black takes, we get the piece back with an attack: 16. exd5 Qc7 17. Qxe7 Rfe8 18. Qh4.

And if black doesn't take, we get a hilarious fritz-generated knight maneuver:15... Bd8 16. Nb4 Qc7 17. Nc2 Bf6 18. Ne3

analysis diagram: Nc3-d5-b4-c2-e3.
15... Nc5
16. Rg3 g6
17. f5!

This position is very dangerous. Black's only hope is to play ...Nd7 and ...Bf6 immediately.
17....Rfe8 This move is totally unrealistic.

Another way to go wrong for black: 17... Qc7 18. Qh5 e5 (18... f6 loses to 19. Rxg6+ hxg6 20. Qxg6+ Kh8 21. Rf3) 19. Nd5 Qd7 20. Bxc5 dxc5 21. Nxe7+ Qxe7 22. f6)

18. fxg6 (18. Qh5!)
18... fxg6
19. Qh5! e5

20. Rxg6+! hxg6
21. Qxg6+ Kh8
22. Rf7

answers to quiz

1. Black should play 28... Qf8 29. Qb7 a5 30. Qxb6 a4. Instead she got mated after 28... Kh7 29. Qf5+ g6 30. Qxf7+ Kh8 31. Rc8+

2. White wins by taking on f6 and playing Bb5+: 1. Bxf6 exf6 2. Bb5+ Ke7 3. Nd5+ Ke6

4. f4! Bxd1 5. f5+ Ke5 6. f4+ Kd4 7. c3#
Black can try 4... Qa5+ 5. Qd2 Qxd2+ (5... Qxb5 6. Nc7+) 6. Kxd2 but now white threatens both 7. Nc7+, winning the rook, and 7. f5+ Ke5 8. f4+ Kd4 9. c3#
