Briachek, lets assume you call. Let's also assume that the flop comes as it does, which is all undercards to your pair of tens. Lets also assume that your oppenent holds AK offsuit (in this case highly unlikely- really doesnt matter down to QJ) Lets take it a step further and assume that your oppenent is a thinking oppenent, that has a basic understanding of pot odds. (odds are in this case he isnt). Lets also assume that when you push in, you flip up your hand so your oppenent can see it before he makes his decision - so he has perfect information. After you push in the pot will contain (running with 10 handed table tho 9 handed won't change it much) 750tc in antes, 600tc in blinds, your 2400tc and your oppenents 2400tc along with your all-in of 2600. If my math doesn't fail me it is 8750tc. Your oppenent has to call (with two overcards) 2600 to win a pot of 8750tc. Effectively he is getting slightly better than 3.25 - 1. His odds of winning the hand are (assuming ak) 24.8% - 75.2% or slightly worse than 3 - 1. Therefore the pot is laying him the correct price to call if he wants to take a shot to double up. You have technically zero fold equity vs two overcards on that flop. You also run the risk by calling of an overcard flopping, and then you are stuck out of postition and have to either push into a made hand or check and fold to his likely bet. Mind you, when you do fold, you are probably folding the best hand most of the time.
Preflop, if you shove-in, and assuming his calling range to be fairly tight (AA-1010, AK-A10 suited or not, KQ-K10 suited or not, QJ-Q10 suited or not, J10 suited or not) your equity is 52%. Not all shabby considering his possible range of hands is much much wider and you will fold most of his Ace rag hands giving your 2750tc risk free not to mention the increase in your equity if he calls with pocket pairs down to 66 along with some suited aces.
I still think shoving preflop is the best option, tho it takes away the ability of a bad oppenent possibly laying down an even money(on a pot odds basis) hand on the flop (two overs). Pushing guarantees that you will not make an incorrect fold, it also gives you the chance to get ace rag to fold preflop, and perhaps some other hands. By pushing preflop, you still retain some fold equity. He will definately call with a hand he beats you with, however he may lay down some hands which are a coinflip. Also, remember that by holding 1010, you add a few points to your coinflip percentage by virtue of taking away some of his straight possiblities by denying him access to two 10s when he is holding overcards.
In my opion, I still like shoving in preflop. You need chips fast. You are in the blinds next and if you fold to overs on the flop you have approximately 2 trips left around the table. Odds are you will not get your money in with 525 or greater equity after this hand. Not to mention that if you do have to fold(say and ace flops), doublling up isn't as powerful as doubling up now.
