Both don't work - for different reasons.
1. Qb8, Kxg5; 2. Qf4+, Kh4; 3. g5+, checkmate
2. Qb8, hxg5; 2. Rxh3+, Kxh3 3. Qg3+, checkmate

Btw, Loyd's puzzle and mine can be merged: On which squares can you place the bK such that white can checkmate it either faster or slower than on any other square?
