What's bad is when your opponent says "you can run it as many times as you want", as it usually means you are drawing completely dead. Standard practice is to burn between cards and boards; provided there are enough cards in the deck.
If you run out the whole deck, you can realize close to your true equity every time...
Upside to running it twice: It reduces variance. The more you run it twice, the fewer mind-blowing upsets you'll face, though of course you'll see more chops. I would run it twice all the time in this hand, but then again, I run it twice a lot.
Downside to running it twice: It reduces variance. Variance is the only feature of poker that allows players to have winning nights even when they perpetually get their money in bad. Reduce variance, and you may slightly increase the speed at which donators get tired of the game (because they don't win enough), which is obviously not good in the long term.
What about running it three times?
I typically only do stuff like that with Marc I think. We have a little history of that kind of stuff, like when I ran it 3 times while drawing dead! But yeah I don’t mind stuff like this even if it means winning less (or losing less). If you say no I don’t mind that either. If you say never I try to remember that too and never ask again:Agree with all points.
Against a casino unknown in that spot, I can find a fold (which may be worse). But if I have a good idea of how this guy plays, it's certainly call-able. Kinda felt like AQ to me.
I'd actually prefer this because it's not a chop. Someone wins 1/3rd of the pot most times.
Of course, if you're AI against @mike32, he'll probably suggest taking all the river bets back, put $10 more in each, then run it twice... That seems to be his MO lately.
The flop TdJcQd. I bet $3, villain goes all in for $20 and dealer folds. What now?
I ran this through a simple solver, FWIW. Assigning him a range of the top 20% of hands minus AA/KK/QQ, on this specific board your hand appears to have about a 55% chance. Not terrible, not great. If his range is wider, and includes a bunch more bluffs, you’re farther ahead.
