"Villain was this afternoon LAG and a light 3bettor saw him 3betting with QTo, K9o. This match he was something tighter didn't 3bet me that much but was opening all his buttons."The part I bolded, combined with being 9bb deep, makes this shove perfectly good.The fact that you have a hand like K9s, which you likely call an open shove with against most opponents at this stack size also makes it easier to more quickly see that the best play is to shove.I would reserve flat calling at 10bb or less vs a minraise for players you absolutely know a lot about (well defined opening ranges, postflop ranges).  And even then, you need to see plenty to exploit and counter to make flat calling this short clearly better than shoving (especially vs a very wide button raiser).Well played, just looks like a cooler, especially based on your reads.

Not so much following the NASH chart.  It's more of IF your opponent shoves a range that you would call K9s against OOP (note, it's often correct to play a little tighter than NASH given that a lot of players shove tighter more often than looser than the sb chart for example), then it should be more clear that it is more than fine to shove it if he is opening his buttons with an even wider range (even if he calls the same % that he would open shove, you still gain value from his folds which makes it even better than if he had open shoved a likely tighter range).It's more of an observation than a rule or anything.  It's just seeing that "hey if I'd call a tighter range shove, I should probably shove over a wider range minraise, it either has some fold equity or calls too often and my hand is actually value."

Make sure to focus on the 10-25bb area the most.  The shove or fold 10bb or less is usually filled with very tiny edge potential compared to the rest of the game (since it's a less dynamic and more boxed in game strategy in that area, there's less room for disasterious mistakes from opponents which makes up most of your edge in the game as it is).10-25bb areas, however, are areas where a lot of opponents will make terrible mistakes, so it makes sense to spend some extra time on that area of the game to learn how to fully take advantage of opponents there.

Is there any videos that specifik focus on 10-25bb? I think that u right about that its really important to master before it gets to push/fold.

I think actually viewing the end game suggestion videos in the learning guide is probably the best way to proceed with studying 10-25bb area play.The last two videos may not interest you much, as I believe the effective stack level is really low (10bb or less perhaps even).  But the first three should definitely give you what you're looking for.  If you can remember, try to update this thread with your opinion of how those three videos helped you.Also, all these videos are available to standard members.  For any premium members, especially those already partially versed in 10-25bb play (and those that have already seen the videos below), a majority of Mersenneary's premium videos are excellent material for this specific area of play (especially the ones that take place in the super turbo structure of 25bb or less).End Game Starting Point Videos (Beginner and Intermediate) Mersenneary Video 8 - Student footage is used to introduce basic end game theory.  Discussion on how continuation bet sizing from the small blind and preflop flat calling ranges from the big blind change when playing at short effective stacks. RyPac13 Video 09 - RyPac goes over the basics of the end game with a hand by hand demonstration through a replayer.  He then plays a pair of matches to demonstrate some of the concepts he discussed.  This video references the NASH Equalibrium.

The only video i watched is ur video 09 which was really good, definitly going to watch that one again and ofcourse the other ones u recommend. Dont remember anything specifik that was good or bad about the video for the moment cause it was i while ago since i watched it, but i really like the use of nash, i use to have the nash chart open to take a look at it if im unsure what to do, but often tighten up a bit specially when calling.But i problem i have is that i dont feel real comfy about start pushing when say 12-20bb deep, but perhaps i should against certain opponents (aggressiv?). I play turbos at ongame and i think its the same structure as pokerstars but the blind rising every 3 minutes. When im 12-20bb deep, if i minraise they often push, if i limp the same, not always ofc but im guessing im loosing a lot of chips that way. Should i just use nash to push/fold or/and try to trap them with limps/minraises with really strong cards?Do u ever push bluff when ur completly card dead, like with T3o like 10bb deep? I guess i have to sometimes when i never catch a decent hand at all and im folding away way to much chips to villian.Sorry for the off topic in ur thread monk :)

The link for Fydor 11 takes me to the subscription page, and since none of fydors vids are numbered i can't find it. could someone post a working link

Links are fixed.  For some reason the URL extensions had the word "content" repeated, so it was causing the links to fail.I don't usually shove or fold deeper than 11bb any longer.  I used to do some shove or fold against players up to 13-14bb deep at times, just the difficult ones I didn't feel any more confident against.I still think that was a fine adjustment for me to make, as I likely wasn't going to get any edge playing another way at that time.  But that's one area I've worked on and I feel more confident for the most part playing non shove or fold in those areas at all times.
