United States Tax Court, Barrish v. Commissioner (1984)
“ We also believe from petitioner's testimony and his manner of betting that he believed he could make a profit from gambling on the dogs. While the race track employees who testified indicated that very few inveterate gamblers win in the long run at the tracks, most gamblers are incorrigible optimists. In order to qualify as a trade or business an activity must be carried on with an objective for profit, but the test is not the reasonableness of the taxpayer's belief that profit will be realized but whether the enterprise is carried on in good faith and for the purpose of making a profit. ”
