It isnt smart to go all in only if its a lock win. But no body expected that Saudi Arabia would turn this match around honestly. A hardbeat is always hard to overcome it is a lesson learned that you shouldnt be all in and that you should make bankroll and grow slowly
There is no doubt that the Saudi Arabian team was considered an easy opponent for Argentina. Even so, it wasn't wise to go all in. But just because he/OP wanted to make quick money. he didn't think for a moment that in this way he would lose his money quickly too. and so it happened.
I think Larry Hite's quote is worth mentioning here.
I have two basic rules about winning in trading as well as in life: 1. If you dont bet, you cant win. 2. If you lose all your chips, you cant bet.
