I play to win. Hence...
I stall when it benefits the cause.
I foul when I see a purpose.
I like fair play....
I don't start pushing my opponent out into the crowd or foul them when the win is 100% secured. (But I will do it if it's only 99% chance of winning)
I don't concede unless...
I am about to retire.
I have unexpected important real life business to take care of.
