You're under the gun (the first player to act) with AT. It's early in the tournament, with blinds of $15/$30. You have $3,000 in your stack. What should you do?

Fold. This is a marginal hand, my position is poor, and I haven't seen what any of the other players might do.
Call. It only costs $30 to see a flop, just 1% of my starting chip stack. I could flop two-pair, a straight, or trips.
Raise to $90. I have a decent ace and should take the lead in the betting. I might be able to pick up the blinds right here.

It's early in a $20 buy-in multi-table online tournament. The blinds are $15/$30. You make a standard raise to $90 under the gun with AK. The player immediately to your left, the hijack, the button and the big blind all call. The pot is now $465 and five players see the flop: 8 9 J. The big blind checks. What should you do?

Make a standard continuation bet of $250. I was the pre-flop aggressor and I shouldn't give up the lead in the hand. There's some chance I still have the best hand, and if not, I should have outs if called.
Make a small bet of $120 or so. The flop missed me completely, but maybe it missed everyone else as well. A tiny bet might represent a really strong made hand. It might buy the pot cheaply.
Bet the pot, $465. I want to show that I'm serious about this hand and drive out any draws that could be up against me. A pre-flop raise followed by a pot-sized bet should be given a lot of respect.
Check. The flop missed me completely. I'm up against four other opponents, and it's simply too likely one of them was helped by this flop. Any player with top pair and/or a straight draw is not going to fold to a standard continuation bet.

It's early in a multi-table tournament. The blinds are $15/$30. The under the gun player makes a standard raise to $90, which is called by a player in middle position. You're on the button with a pair of eights. You have about $2,800 in your stack, similar to your two opponents. What should you do?

Fold. It will be tough to play my pocket eights against two other opponents. Overcards are bound to appear on the flop, and then I won't know what to do with my hand. Medium pairs are tricky to play.
Call. I'm in position with a perfect trapping hand. For a small investment of $90, I can try to flop a set. If I hit my hand, I could make a fortune here for a small investment.
Re-raise to $360. The middle position player didn't show a great deal of strength by merely calling the under the gun raise. A pair of eights may well be the best hand at the table. I might be able to take this pot down right here.
Raise all-in. My pair of 8s may be the best hand at the table right now, but they'll be very difficult to play after the flop when overcards appear. I can't fool around with small ball poker when I can take this pot right now.

You're on the button with your pocket 8s and a stack of $2,800. The blinds are $15/$30. The under the gun player made a standard raise to $90, and was called by a middle position player. You called on the button, the small blind folded and the big blind called. The pot is now $375 and four players see a flop of: Ah Ks 8s. The big blind bets $60, the under the gun player raises to $250, and the player in middle position quickly calls. The pot is now $935 and it costs you $250 to call. Action is on you. What should you do?

Fold. There's been a bet and a raise ahead of me and I only have bottom set. The under the gun player might have raised pre-flop with aces or kings and hit a bigger set. It's not worth risking so many chips if I'm drawing to one out.
Call. With bottom set, I almost certainly have the best hand right now. And there seems to be a lot of interest in this pot, so by calling I may entice the big blind to call behind me as well.
Raise to $1,200. I have a very strong hand and want to build a big pot here. If I merely call the big blind may stick around for only $190 more with any draw. I want to charge the straight and flush draws a maximum price.

Same pot as the last question. You raised to $1,200 on the button with your set of 8s on a flop of Ah Ks 8s. The big blind and under the gun player both fold, but the middle position player again flat-calls (he also smooth called the UTG player's initial raise to $250). The pot is now $3,085 and you have $1,510 remaining in your stack (your opponent has you slightly covered). The turn is the Qs. Your opponent bets $500. What should you do?

Fold. The queen of spades is a disaster card for my hand. My opponent couldn't have flat-called two large raises with anything other than a spade flush draw or straight draw, both of which were helped by the queen of spades.
Call. My opponent's betting pattern would seem to indicate a flush, but he's left me good pot odds to draw to a full house.
Go all-in. If I lose this pot I'm pretty much finished in the tournament anyway. Plus, there's a chance my opponent wasn't on a flush draw.

Middle stages of a single table sit and go. Six players remain. You're on the button with AK and a stack of $950. The blinds are $25/$50. Everyone folds to the loose, aggressive big-stacked cutoff ($4,500 in chips) who raises to $150. What should you do?

Call. I have position on my opponent and want to see a flop before committing the rest of my chips. If I miss the flop, I'll still have $800 left to try to make something happen.
Min re-raise to $300. I want to get a little more value out of my AK but don't want to lose my customer with a larger raise.
Go all-in. There's $225 in the pot (roughly 25% of my stack) and I don't mind whether the loose big stack calls or folds. I need to make a move here.

Final stages of a single table sit and go. Four players remain, and three will be paid. Blinds are $200/$400. The tight, but very aggressive chip leader ($7,000 in chips) raises all-in under the gun. The button ($400) folds, as does the small blind ($2,500). You ($3,600) wake up with QQs in the big blind. What should you do?

Call. I have the third-best hand in hold em (only AAs or KKs are ahead right here) and I have the chance to build a monster chip stack. I need to take chances at some point.
Fold. The button is desperate and likely to be blinded out the very next hand. Despite my strong starting hand this is simply too great a risk. Even if I fold I'm still in great shape.

Middle stages of a single table sit and go. The blinds are $75/$150. Five players remain, and three will be paid. The under the gun short stack goes all in for $700. The middle position player ($1,850) folds, but the somewhat loose, aggressive button ($2,875) calls after some hesitation. You are in the small blind with $3,275 in chips and AKs. The big blind remains to act behind you with $4,800. What should you do?

Fold. I'm in solid second chip position and although I may have the best hand, it's just as likely I'm gambling with one or both of these players on the bubble.
Call. The button and I can collude in taking out the short stack and moving the whole table closer to the payout. If I miss the flop, I can safely cut my losses.
Raise to $1500. I want to build a bigger pot with my AKs, which is probably the best hand. Make the loose button pay to see the flop.
Raise all-in. This is an opportunity to squeeze the button and punish him for his loose call. I don't want to play AK in a three-way pot out of position.

Middle stages of a multi-table online tournament. You're the current chip leader at the table, with what should be a tight aggressive table image. You've been making a lot of position plays and stealing pots pre-flop without much resistance. In fact, pre-flop raises are rarely getting called at this table. Everyone folds to you in late middle position and you find 66s. With $5,475 in chips and blinds of $75/$150, you raise to $450. Everyone folds to the tight, aggressive short-stacked button, who goes all-in for $2,575. Both blinds fold, and action returns to you. The pot is now $3,250 and it costs you $2,125 to call. What should you do?

Fold. The best-case scenario is that I'm racing for ~40% of my stack. If I call and lose here, I'll have a sub-par chip stack with fewer playing options.
Call. The short-stacked player could be making a move, and I'm being given odds to gamble. I'm probably racing with $1,125 in dead money in the pot to compensate me.

On the bubble of a multi-table tournament, with eight players to go until the payout. Blinds are $300/$600. Flops are few and far between here, as pre-flop raises are not being called by nervous players waiting to make the money. You're in the hijack seat with 43s. Everyone folds around to you. You have $3,175 in chips. The cut-off has $4,900, the button $6,085, the small blind $5,172 and the big blind has $3,675 after posting. What should you do?

Fold. My hand is useless and there are too many players to act behind me who might wake up with a hand they can call with. I'll wait for a better spot to make my move.
Raise to $1200. I want it to look like I want action but still leave myself a chance to get away from the hand if the action behind me is truly ugly.
Raise all-in. Five players have folded in front of me and I have enough chips to frighten the remaining players. Even if called by what is certain to be a better hand I might get lucky.

Early stages of a 20 table sit and go tournament, blinds are at $15/$30. The UTG+1 player (second to act) with a $2,900 stack min-raises to $60. Everyone folds around, and you ($3,225 in chips) call on the button with 2c 2s. The small blind ($2,995) calls and the big blind folds. The pot is now $210 and three players see a flop of: 8c 3h 6c. The small blind checks and the UTG+1 player bets $90. What should you do?

Fold. I missed my set and three overcards have appeared on the flop. The UTG+1 player indicated strength with his pre-flop bet and flop bet.
Call. The UTG+1 player has made a cheap bet and I might still have the best hand. I'll call and see what he does on the turn.
Raise to $270. That flop should have missed any hand the UTG+1 player might have and his bet looks weak. I want to try to take the pot down right now.
