That is a very lucky, great result. Way to hit the big one!
I think about luck all the time where betting is concerned. You know: One team’s shots go in, the other’s shots don’t. Sometimes it's both: like today, where a manager chooses a defensive strategy that leads to seven offside traps, and then the Saudis' only two shots on goal go in. It's the way it always is with football. You can credit the defense, scream at the officials or curse God if you think it’ll help you cope, but I think random chance is mostly the culprit.
I was run over by a car six years ago, which was extremely unlucky, but the scans they did of me (I had a traumatic brain injury, among other things) found that I had thyroid cancer, which caught early is not that big a deal. Very, very lucky.
I feel unlucky, betting-wise, and roads taken or not taken are a big part of it. For example, my entire strategy is based on odds thresholds — if the number is above this line, I’ll consider it, if it’s below, I won’t. Plenty of matches start with odds I’ll consider and then, closing odds will show that the match should have been skipped. I’ve bought myself out of some of those bets a couple of minutes prior to kickoff (one of my books allows this), and damned if those aren’t the bets that win most consistently. Similarly, one of my books offers a “cash out” option, where it (assuming that my bet is currently winning) offers a small percentage of winnings that rises as the match goes on. On a small number of occasions, usually when I’ve been on a losing streak, I’ve cashed out a bet 10 minutes from time because I know, the way things have been going, the favorite will score at the death and lose me my stake. But every time except one, I believe (I might be forgetting my successes), I’ve cashed out bets for two or three units that would have won me four.
Maybe I only feel like this happens, as opposed to it actually happening, but every time I skip a bet willfully (because of something I’ve read that scared me off) or miss betting it entirely (because I’ve gotten a phone call from a client and forgotten about it), I miss a winning bet. But when I take a bet five minutes into a game, finding that the odds are essentially what they were beforehand, the bet loses.
Yesterday I took the draw in Netherlands-Senegal, and it looked really, really smart...except for the result. For 84 minutes it looked really good, and lucky. There are lots of underdogs I'll consider, and some I'll take. I won with the draw today with Denmark-Tunisia at 3.85. But I'd never have considered a flyer on the Saudis, given that, you know, until this one there had never been an outright win by a 25.00 dog.
So you're very, very lucky, in addition to being good. I can't fault the logic at all.
