The point of the question was not to determine a term, but to indicate what the player did.
Placing a bet knowing that this bet is controversial to your previous bet, which will eventually help you to be in profit in any way - that's an example of unsportsmanlike bet.
I don't understand what you mean by a controversial bets I've been gambling since 2011 (10 years) so I should know better I know your site is not up to 3 years, so lets go practically because you mentioned the player trying to get profit in any way so if I should place a bet on; Man utd vs Chelsea game.
1st ticket: I place Manutd win
2nd ticket: I place Chelsea win
3rd ticket : I place on Draw
Is this an example of what you called a controversial bets? Because no matter the outcome I'll still gain and loses at the same time. If I'm wrong then tell me practically.
