it is much better situation than what happened to me now and usually happens with big players and that is that they hit some crazy accumulator bet and all you can hope for is that he will lose what he won... if he deposited XX,XXX it is most probably really whale
well when i was betting i was using exactly this time consuming strategy... playing small amounts on slightly -EV bets and then hitting hard with redeposits, no professional can do this on daily basis for months for sure
if you want to be sure ask AM what he is betting on, when and at which odds and compare it with some line service and you can sleep well afterwards
