Guess 2 put the E and L in new locations, and tested for remaining vowels.
After guess 2, my first inclination was to make STEAL my second guess, because that put all the known letters in new positions, and added S and T, two of the most common consonants. Then I reconsidered. - STEAL was the only word I could think of that fit an xxEAL pattern. I liked keeping EA together, so I considered putting the L ahead of EA, giving me a xLEAx pattern, for which there were three possibilities - CLEAN, GLEAN, PLEAD. So I figured that xLEAx was more likely to be correct than xxEAL.
Since two of three words in xLEAx path ended in N, I opted to use one of those words. If the xLEAx pattern was correct and I guessed wrong I would know which of the two remaining words was correct. And if the xLEAx pattern was shown wrong, then I could go back to STEAL, if that was still viable.
I chose CLEAN, and while it was incorrect, it eliminated PLEAD, leaving GLEAN as the only choice.
