Yes it is. I'd imagine that at the normal-stack regular-speeds the theoretical ceiling is somewhere around 70%.

You guys advocating waiting for a better spot because you only have 53% chance of winning -or whatever your number was-: you do realise that you already put 140 in the pot, right?

lol wat.

I'd be interested in prop betting you maintaining a 75% winrate over 500 games in reg/turbos sng (not placing this bet if u play NBI games).

Apologies for getting into this and I want to emphasize that it wasn't intended as a brag because I was a terrible player, but NBI games are primarily what I used to play and it's been a while since I grinded HU SNGs. My playing style has also changed considerably since I posted this. My HU matches don't last 3 hours like they used to. Before I played mostly as a weak tight nit and trappy: just wait for the right flop and let them pay me off for it: be aggressive just enough to avoid losing too much from the blinds. There's no way I could have done it the way I play now: a lot more aggressive pre and post and occassionally flat calling the river with something like bottom pair or king high when I think it's the best hand. I actually didn't know how to play HU at the time I was doing so well and that probably irritated the hell out of my opponents since I'd fold even middle pair on the flop to a cbet. I didn't make a single bluff.

As people replied to me before about this, I wouldn't be able to maintain such good stats even if I was dealt pocket aces each time and shoved pre, but I wasn't ever shoving pre before and was so much of a nit that I wouldn't even 3-bet with AJ, e.g. and would never call a shove with it unless the villain was so low in chips that I'd double him up by folding.

The style at least used to work quite optimally from a win rate perspective against the competition, but horrible in terms of hourly rate. It probably wouldn't work now with so many regulars grinding HU SNGs - that style only worked when I was seeing flops for cheap. Looking back now, I was probably boring my opponents to death with the fit or fold strategy I was using and I wasn't making much from it because, as mentioned, the matches often lasted 3 hours on average and sometimes as long as 8 hours.

The opponents were also very easy back then. Most didn't even raise the button, and if they did, it was a min-raise so I could see many flops for cheap, shoving all in when I have a boat and they got a flush, etc. I just waited for the moment when they had a made hand or bluffing and I had the nuts. We were deep enough for me to wait that long even if it took all day.

I was also a horrifically bad cash game player because of my fit or fold style (I lost too much calling raises and far too tight to be making money and cash games player picked up that I was weak tight and wouldn't pay me off for my made hands), but these HU SNGs, at least at the time, were just perfect for my weak style. It was an easy style to exploit (just make me pay more to see flops and drain me out from all the folding I was doing and don't pay me off when I'm not folding), but no one exploited it back then, and I mean no one: not a single person.
