When l em a one of the shortstakes in some tournaments l just wait for good hand. For me this is only good strategy. Bluf is inposible becose you have a less chip than others and if you bluf some player he will call becose he will not lose so much chips. Good hand for me in freerolls and low buyin tournaments means any pocket pair or ace with someone card. If l em short stake on middle or late phase of tournaments l will try to doubleup with pocket pairs TT+ or AT,AJ,AQ,AK or some A and another suited card.
