Guesses 1 and 2 were standard vowel hunting, along with a few common consonants.
Guess 3 was selected to suss out the location of the A, to check whether the word might have two As, and to investigate three more common consonants.
After guess 3 I know that positions 3 and 4 needed to be two consonants that can fill between the A and the Y. ALKY came to mine, so I tried to solve with BALKY. When the wasn't the answer, but it added a K in position 4, I was really perplexed. GAWKY was all I could come up with, and I wondered whether that was even a word. But since I couldn't think of anything else, I tried GAWKY and it worked. Afterward, I looked at the puzzle again, and I realized that HANKY would also have fit at Guess 5, and if I had seen that I certainly would have used that instead of GAWKY, which means I would have put in GAWKY as guess 6.
