I disagree with that...okay yes u have 30 hands left but lets say u wait and shove on the 22nd hand. okay now u win bc u waited but what do u have now. Nothing ur back were u started with a major short stack. and the blinds are getting ready to go up. The 10bb rule is very bendable. heres why... late in a tourney a lot of ppl barely have 15bb and they are in the top ten...so the 10 bb rule is really effective depending on the stage of the tourney. mid to bubble then yes 10 bb rule is effective..but after bubble i would say that goes in half bc when u shove with it you have enough chips to make ppl only call u with premium hands and they are trying to make it as far as they can so they dont want to call anything. so u get the blinds and antes and u just went up a good amout of chips...bubble play is the same way about ppl folding easy..but the 10x bb rule is there bc if its early then u have to make a move to get chips or u dont have a shot of winning it.. and u cant win it without chips
