Definition of trash can
In English, a hand is said to be "trash" or "rag". These are hands that need to be put to bed. A "trash" hand is more precisely a garbage hand. A trash hand is an unplayable hand, whose long-term success will be very low. We'll talk about premium hands, like AA or KK, good hands like 88-99, average hands like 89 suited, bad hands like J7 and trash hands like 27 unmatched or 92 unmatched. Garbage hands are at the bottom of the poker hand scale. A trash hand is a hand without much hope.
Even a matching garbage hand is still a garbage hand
Some recreational players like to play just about any matching hand. In their minds, the probability of making a flush is huge with a matching hand. Don't make that mistake; a matching hand is about 5% better than the same non-matching hand. So if your hand has an overall equity of 22%, even adding 5%, you are still far from being in profit. When you have a trash hand next time, matched or not, just fold it and wait for the next one!
