Any advice on closing strategies?

[CleanUpMan]

I just started playing online in July so I'm still pretty new and looking for advice. Playing MTT, I have made 2 final tables and finished somewhat deep in 2 others in the last few weeks. I play a very unimaginative TAG style. ABC poker seems to work well for me in these tournaments until the bubble bursts. After that, if big hands elude me, I usual go out with a whimper as the blinds and antes eat me alive. I just can't bring myself to make moves with suspect hands late in tourny. Is it really all about finding and pushing +EV spots? If so, is this the only way to go about closing strong or are there other stategies to apply late?

Any advice would be appreciated, thanks

it is pretty much about finding and pushing +EV spots deep in tourneys. blind stealing etc
