Bad Beat is a situation in poker, when a player with a strong poker hand combination loses a hand to an even stronger hand of opponent that initially had very small chances to win. That’s why not every lost hand can be considered a bad beat. As a general rule, bad beats are situations when a player with the worst hand initially had from 1 to 15% to win. Thus, as a result the hand is won by a player, who at the early stages of a hand had no more than 2-4 outs.

If on the flop you had over 90% to win, but you have lost the hand, then you have suffered a bad beat. However, if you had lost all-in with 60% to win, that was a coin flip.

Example: 'On the preflop I have gone all-in with pocket Aces, my opponent called with a pair of Tens. As a result, one more Ten hit the river and he finished his set. Brutal bad beat'.
