So many questions.

1/ I likely fold pre-flop. You have no read on the guy. He makes a 4xBB raise in early position. He *should* have a strong hand. So you are either a slight favourite or a huge dog. And you *are* a huge dog. Plus you are out of position. Only thing in favour is you are last to act on this round so you can close the action.

I'm not sure how you come up with 12.5 to 1 implied odds. Is that because the most you can get out of this guy is another 77 bucks assuming you have a better hand and get all his money in? That's a pretty big assumption. In fact you *did* get all his money in and end up with a better hand. Since his stack isn't that large, I'd actually be more in favour of folding now. You can just barely get paid off enough if you outdraw him.

2/ His bet on the flop was to protect his overpair. He didn't miss the flop - this was a perfect flop for him as long as you didn't hit a set. It is highly unlikely you would have hit a straight. So he's protecting against any possible draw you might have. He could reasonably expect that you'd fold at this point. I'd say he overbet a bit - 28 bucks into a 17 dollar pot. It almost looks like a bet that doesn't want a call and very nearly commits him to the pot. If you were sitting back with QQ or hit a set, he is gonna lose all his chips. You made a bad decision to stay in the hand at this point. But we have to add in the pokerstars factor.

3/ Your raise is a strange amount. With 10 outs you are an underdog yet you only min raise. Calling is not an option for him now as this won't leave him enough chips to do anything with anyway.

If he's bluffing he should fold and if he has a decent hand (he *does*) he's going to get the rest of his chips in. Your raise basically says 'go all in if you think you have a decent hand'. And of course, he has so few chips to re-raise you won't lay down your hand anyway. So you are risking $75 for a chance to make $45. Myself, I would have probably folded on the flop rather than raising. Since I'm the underdog and it is unlikely he'll laydown here, I might just call and see what happens. He'll go all in on the turn in most cases anyway. So one way or the other, it is going to be very expensive to try to draw out.

If you wanted him to laydown on the flop, you had to push all your chips in instead of min raise. Unfortunately in this situation, he would have called anyway.

Congrats on getting lucky. Enjoy pokerstars, the home of the underdog.
