21:50 How about checking back the turn to induce a bluff on the river?
And one more question, do you multitable these ?
Against a loose and/or aggressive opponent, this can work for a few reasons:
- Vs a loose player, you can still overbet jam the river and get most flushes to call.
- Vs an aggro player, you can expect to get enough value from bluffs + see him sometimes lead weaker flushes (so you lose minimal value vs flushes by checking the turn and you gain more than you lose from bluffs).
However, vs a player that you don't have that information on, I think you do lose too much value vs flushes. You see guys check low to mid flushes on the river to you and they might consider folding vs an overbet jam, so now you have to bet a more reasonable pot sized bet or less and now you don't get all in. Compared to if you bet a small amount on the turn, they aren't folding any flush, and then the stack you have left on the river is only around half pot and they're not going to fold on the river either.
So you have to weigh what your opponent would do in both situations with stronger
hands such as flushes, vs what your opponent will do with weak hands (bluffs/pairs are essentially bluffs if they have no flush now too) if you check vs bet.
Multi tabling - I haven't been playing regularly this year. Historically, I two tables turbos and I played anywhere from 2-4 hyper turbos. This year, when I got back into playing, I single tabled awhile, and after ~400 games or so I started adding in two tables again.
I'd recommend just playing one table while you're learning, two if focus is a major strength of yours, and just add tables as you're more comfortable. Don't rush it, and it's also a good idea to drop down a level or two when adding tables, it's easier to get comfortable when the buyin is lower than you're used to.
