Hello guys. Just joined and would appreciate your help and insights . I am a fairly successful headup player....love the game. I have a great small stack play and can often come back from fairly bad beats having mastered nash and in general small stack play (maybe because as a beginner I spent most of my time as the small stack!) My problem now is when I am the large stack in a standard sng say 2000 chips vs 800 or so I have great difficulty at the moment . The vilain frequently comes back on me and we end up even or worst I lose. Now there is very little literature on the strategy needed. Most books talk a lot about small stack play but very little is writen on large stack play ( hint hint) . When I am aggressive I seem to lose most of my all ins even to AA sometimes ( to the point I wonder if sites are rigged) . When i small ball I often find myself back to even. What can I do to fix this. I dont want to rely on luck there must be a correct strategy for this situation.
Literature - There should be plenty available. 2200-800 isn't that deep stacked either. At 10-20 blinds, that's 40bb effective stacks, at 15-30 blinds, that's under 30bb (and considered fairly short in the grand scheme of things). There are tons of pieces of good strategy available (other than Mers free ebook and Will Tipton's book, you won't find any short stack books either). I'd advise going into videos.
Videos - The Premium Pack has 800 videos, both short stack and deeper stack play. U cnat spel did some great turbo speed videos in the premium pack, I'd also check out Mersenneary, HokieGreg, Sa1251, Coffeeyay, h2olga... there are countless others too. Greenbast turbo speed pack might also be good for you, it'll be more of the 40-75bb stack recommendations for you.
AA stuff - Nothing can help you not lose with AA if you get it in good. That's just a bad beat, but not likely your real issue (if it is, variance will change at some point and you'll do very well).
Small ball vs aggression - You should try to avoid thinking in general strategy or style terms. Don't "play aggressive" or "small ball" you should be focusing on what your opponent is doing then building a specific strategy to exploit them. For example, if your opponent is calling a lot preflop, but folding a lot of flops, you would raise a lot preflop and bet a lot of flops. If your opponent is 3betting you relentlessly, you might try limping and open folding a few hands, raising a bit of a stronger and tighter range, and 4betting a little wider/calling 3bets with strong hands that flop well (depending on their postflop characteristics). You should strive to learn how to adjust to different opponents if you want to improve your play. Don't fall into a set style of play, that will hold you back from beating many players, as no one style can beat everyone, and no one style comes close to being the right decisions hand after hand vs anyone.
