K/10 o Vs Q/3 of Diamonds. Was I wrong??

Yesterday I played in a Freeroll on PokerStars.com and about mid ways through after losing and hand on a Flush Draw a few hands earlier I went All in with K/10 Off. I had $570 Remaining from a starting stack of $1,500 I was UTG2 folds all around to the SB who had $610 Remaining after taking time to figure odds player called with Q3 of Diamonds. Now I know I'm not supposed to put results in the thread but I also don't know how to to a hand converter either so. Anyways player hits a 3 on the Flop and I brick the entire board and get knocked out. I know I probably could have picked a better spot to go all in but I didn 't want my stack to get much more depleted and end up having to go all in in an ever worse spot. Was I wrong to go all in am I still worlds behind or did player just get lucky? Any input is apprecaited. Thanks.

It depends on the size of the blinds in relation to your stack. Here is a chart that has unexploitable shoving and calling ranges for various stack sizes in BB in a heads up game. While not 100% applicable to a FR tournament it is fairly useful in determining the types of hands you should be shoving and when.

Thanks for the link Donachello, it will prove useful to me as well.

It could be argued that this is a bad beat thread, but instead I'm going to lean towards it being a "I have no idea about when tournaments become push/fold but realized something's gotta give when I have like 3bb omgwtfbbq".

A good start would be any of the books Harrington on Hold'em Vol 2, Kill Everyone, or Kill Phil (as far as I know) if you have access to any of them.

For heads-up ranges for shallow stacks, Are You Sage? Getting an Edge in Heads-Up No-Limit Hold'em - Card Player Poker Magazine - CardPlayer.com is an easy system to learn that is very close to unexploitable.

Sklanski's book called No Limit Hold 'em, Theory and Practice has a decent chart in it that gives a good idea of when to shove with which hands.

If you have HEM you can run hands through SnGWizard pretty easily (comes with a 30day trial) but it won't give reasons, only recommended actions.

Thank you all for the help. I find all the links and books you suggested very useful. I do have the Dave Skalansky No Limit Hold Em Theory and Practice. I'm going to start reading it right away. Thanks.
