In hand 749235333 TonyLoroRuiz makes the last raise on the river and htoivonen calls.
There follows the ‘Showdown’
- If there are no river bets the first player to act shows their cards.
- If there was a river bet, the last player to make a bet or raise shows their cards first.
Once a player has revealed their cards, the next player in a clockwise direction shows their hand if they win (automatically in an online game) or they may have the option to ‘Muck’.
TonyLoroRuiz shows their hand and htoivonen cannot beat it, therefore they have the option to Muck. Depending on their personal settings, they could have Auto Muck turned on, or they could have the choice to Muck or Show at the time of the showdown. They do not have to be all-in to be able to Muck.
For fairness / transparency, since this is a Showdown, all the showdown cards are visible in the Replayer to the players who were dealt in the hand.
If a player folds or mucks their cards (to no bet) during the hand, their cards are not revealed in the Replay.
So, yes it is normal for a hand to not be revealed to all when they call and do not win.
In Real Life, the losing hand in a showdown could toss their cards towards the Muck and concede the pot.
It is allowed, but bad etiquette, for another player in the hand to ask to see the Mucked cards ‘I want to see that hand’ (IWTSTH). Players have been known to ask to see hands which turn out to win the pot, through a misread by the caller. The hand might be considered dead if it touched the Muck pile of folded cards, but some venues allow the player to now claim the pot. Not relevant here, but FYI.
