Do you have the GUTS to win? (Restealing)
The first thing that is important to note about restealing is that it takes guts. In order to use the resteal, you have to put it all on the line. You need to own the idea that your tournament life, in itself, has no value whatsoever. You need to own the idea that this could be the last hand that you play. You need to own the idea that you are attempting to win it all, and that nothing less than first place is acceptable, and you need to own the idea that you may end up looking like a fool if you are called.
Restealing (the act of reraising a probable steal-raise) can be a true difference-maker and vault you into contention, because you can potentially make three times as many chips than you can with a run-of-the-mill steal attempt. Using this tactic, you don't necessarily have to put yourself at risk as often as you do during a steal to stay ahead of the curve in a tournament. In fact, successfully restealing once in three orbits while playing no other hands is approximately a break-even proposition! This is especially important during those critical points in a tournament where you are getting no cards and no good steal opportunities. It is the ultimate chip accumulation tactic!
