Definition of suckout
An suckout in poker happens when we are very favorites to win the hand, but the card we didn't want to see shows up. For example, you're all in at the turn on 2-2-5-7 and you have AA. Your opponent calls your all in with KK. Here you have a 95% chance of winning the hand. If a K falls on the river, which will happen a little more than 4% of the time, you will be said to have an suckout.
How do you react to the suckouts?
The suckouts are inevitable. If you play poker often, you'll have several of them a day. The important thing is to stay Zen and continue to play your A game, and not let the tilt be more expensive than the suckout. If you lose your temper, you'll end up losing more money on a spew than on an suckout. Some players are able to cash out well and continue to play good poker, but others are not. It's important to get to know each other well. If you're the type of person who loses your temper when you experience a big suckout, take a break and come back to the tables a little later.
