Well if you don't re-buy straight off the bat, and a large percentage of the guys have double your stack, the only plays that make sense are to shove or fold the relevant range, as you'll be shortstacking when the blinds go up.
The thing about super turbos is they have intense variance due to the fast blind structures, so to crush them online is tough enough, and you need to have your own play cracked to make it profitable.
To do it in a live tournament is a whole different story, which basically means, the casino tourney is a crap shoot, playing overly aggressive & shoving or folding from the second the blinds go up may very well be the most profitable way to play these, and by profitable, I mean over a decent sample size, which is not possible to attain in live-play, as it takes far longer than playing online.
It is an attractive tournament to play for the reasons you mentioned, you know it'll be over soon. Bear in mind it's designed by the casino to appear attractive, but it is more or less a lottery. Again, they are IMO fantastic to build up your live experience, as its relatively cheap + nice format to play. We need to appreciate this from the casino's perspective, which is: If the blind structure would be any slower, we couldn't expect a reasonably large field to exist during the tournament. In the case that the blinds would increase slower, equally so would the expected player quality, as we expect them to recognize that slower blind structures are more profitable. Equally so, we expect player quality to decrease along with any decrease in time between blinds.
It is for this reason, that a shove or fold game will be profitable, only shoving for a top percentage of your hands if your deep stacked makes sense. And when blinds increase to decrease your BB's, open your range slightly when, for example, shoving on weak blinds.
My advice:
1. Minimize BI losses: Don't insta re-buy, take your 1500 and try to double it up, if you manage to do this, your already ahead as you still have your rebuy (I know it's unlimited, I'm taking in terms of total Rebuys purchased) On the back of this, if you bust, just leave & wait until the next week. Additionally, set a stop loss for your Re-buy limit, one or two per week for example.
2. I'm pretty sure when the blinds increase they double the amount of chips received when re-bought (£15 for 3k, instead of £10 for 1.5k), although I don't know if the blind increases make it unprofitable to play tight until this stage, most likely.
The tricky thing for me, and most interesting, as well as what makes these tournaments most attractive is basically the gamble involved. Players with MTT experience will know what needs to be done to make these profitable, which is shove or fold a lot, over a huge sample size. Again, not possible to attain in live poker in a short time, especially with weekly tournaments. Best thing to do is learn how your opponents play, make reads on them, etc.. You need to consider if the amount of effort put into this tournament is worth the amount to be gained from it. It depends on where you are / how many people are re-buying, as this affects the size of the prize pool. Take note of anyone playing shove or fold, and stay away from them, until your deep & final tabled, otherwise, you'll most likely get put out more often than not. Of course, call them all-in with nice hands, and in the meantime, just try to bully the weaker players & crush them, take their re-buys in the form of chips instead of buying them from the floorman
My advice if you want to get serious about MTT's;
1. Play the £5 tourney each week for live-practice, if you cash it's a bonus. Keep in mind there is a low chance of cashing in this frequently
2. Study our MTT materials
3. Play the £50 Freezeout the Gala run on a Sunday, with the slow blind structures. (We expect player quality to increase here of course, & keep bankroll management in mind, £50 is a steep buy-in)
One thing to watch for: I was playing in the Gala in Spain, and a loud, young, what I considered to be spewy at the time, Spanish guy, had position on me, so we built some rapport, played some pots, but he was a tough player & I remember noting this to take care in future after I busted him. Right enough, next time in there, this same guy is a Poker dealer, employed by Gala.
I'm not sure what their policy on this is, but keep your eye out for it. As I'm sure you can imagine, Poker dealers are quite good at Poker.
Take care - If your hitting the freeroll tonight, let me know how you get on.
All the best,
