Yes there are tricks.Here's some that i personally experience when i playing gambling.
1. Scout as possible search for the nice team,stats and condition of the player.
2. Prepare your self when you gamble don't be greedy,stick to the plan and strategy, bet low so that it will not hurt you if you lose.
3. Stay what game or played that you have.If your playing basketball then focus on that.
I don' think these are the tricks to win in gambling.
You are telling some strategies to cut out the losses for the OP,but he is asking any available trick to win a game.Obviously there is no perfect trick available to win in gambling.
