Your poker life will be a easier when your opponents go on tilt, and your expected value will jump so high to levels you cannot even imagine. When the other players go on tilt, they will be playing so aggressive and so wild that practically, he will be giving away his chips. This is quite contagious too when other players see over aggressive players playing terrible hands and winning some pot. It is a party and it is a party from which you can bring home a lot of cash, if you only keep your balance.
It is a risky trick though to join the tilt party. You will lose some money and you might go on tilt and lose control yourself.
How far should you go?
Is it ethical in the world of poker to «help» someone go on tilt? The answer really depends on you. Some will try everything to upset other poker players. They can play so slow, talk nasty, or call people names while others go as far throwing cards and chips to their opponents. Personally, I have not gone as far as this.
Sportsmanship, if you want to call it that, should be your way of play. Encouraging an extra drink or stretching the hours a bit on the table should help and sponge out some money from the other players.
On the edge
You should monitor if a player is about to go on tilt. Study what are his triggers and go for those triggers. If a player is about to tilt, on the brink of going on tilt, all he need is a a little nudge and the party should begin.
If you are not sure if another player is about to tilt, ask questions. Probe in a way which does not reveal your true intentions. Simple questions like «how’s your game so far?» might tell you a lot. People can give you valuable lessons.
