Houdinis really dumb ( other than in end game play ) despite its strength , its can find many better moves than it made in20 minute game play with simple 5 minute analysis , so why did it not make those moves

in a recent 20 game it led as black by -0.80 on book closing ,, few moves later it was losing by that same margin , and went from bad to worse , when game was analyzed (by itself ) it found some better moves late on in game but did NOT find a blunder
Stockish 1.5 JA found the blunder more or less instantly and the move gave lead of -1
3 other engines failed to find any blunder , ergo to my simple brains logic stockfish is smarter engine and should be able to beat houdini
but it doesn't

answers in non geek speak please
