As a compromise, see if you can set a 100BB buy-in max and a 25BB or less buy-in min. Remind them just because you CAN buy-in for more doesn't mean you HAVE to. If you can't do that, I'd probably just leave it alone @ that point. If the game is as soft as you say it is, if anything you want to RAISE the blinds so you can get more money from them, not lower them. In a short handed situation like 25BB, be prepared to buy back several times to handle the swings - remember buying back 3 times would give you just one normal 100BB stack. With 25BB, in one hand you could easily go in with the best of it and lose half or more of your stack if villain draws out or gives you a bad beat. Hopefully they'll at least let you reload before you go completely broke. If so, make sure you always have more than half your stack if not a full one because you're looking to double up and you don't want to get caught even more short stacked once the opportunity presents itself. The main thing to remember about buying in short in a game like this is that you don't have a lot of room to do things like bluff, information bets, blocking bets, or even cbets many times. Every chip that goes into the pot needs to have a calculated, distinct purpose, which 9 times out of 10 will be to extract value - YOU have the best hand and want money in the pot to get paid for it. If you're fortunate to get your stack up to 100BB, you'll be in great shape to start playing real poker and even bully the table because they'll be in the same situation YOU were in and they now don't have any wiggle room. And for you, this is even better news because they won't understand how to be successful with the short stack and will either overvalue or try to get cute and thus give away chips even faster.

Feel free to discuss strategy further, since he did provide a lot of detail from which to expound from, but for me personally (sorry to be a wet blanket ), such games do not require such deep analysis. I go into a game armed with my skillset, a general tight/aggressive/aggressive style and as information about my table unfolds, I adjust accordingly when needed. I've played in a lot of games like the one described above. To be successful, you mainly need patience and a basic skill set. By basic, I mean that you don't raise A4o in early position, can fold AJs to a raise or reraise, don't go broke with top pair, and the like. The hallmark of games like this are players that play too many hands and overvalue them. So, if you are playing tight (good cards) and properly valuing them (understanding when you've got the best hand), you're going to be a big winner long term. Patience is just very important because you may often be tempted to make things happen or take over the game because it's easy.

One more thought I didn't mention before is that observation is always important, but can pay off even more in games like these because players tend to play very predictably and don't mix things up. You want to pay special attention to how players will pay you off: do they like to chase draws, what hands do they raise with, what hands do they call raises with, what hands do they have trouble laying down, and the like.
