FYI: that hand was not even K/7, it was actually 8/7 suited vs 5/5, which is a TOTALLY different discussion.
Hopefully you have turned stupid off so lets discuss the difference between those two hands.
K/7 off suit. What are you trying to do with that hand? There are some many dangers playing that hand.
They are not connected so your strait possibilities are very limited unless you use only one card. Like I posted before a ONE card strait is dangerous because in EVERY case but one you can be up against a bigger strait. So right off the bat the 7 can NOT make a nut strait. Only if your K makes an Ace high strait are you safe but you do not enter a hand expecting to make a one hand strait that is the nuts.
They are not suited so you will have to make a one card flush. 7 high flush is dangerous, especially if you need four board cards to make it. K high flush is pretty safe but again there is a danger if you need four cards on the board to make it. If they are suited you are ONLY going for the flush and that is a safer play but still not a hand I would play unless I'm running hot, in late position, one of the blinds, or playing "limit" poker.
Hit your K and you have kicker problems.
Hit you 7 and you proably have bigger pair problems.
So the only real positives of playing those cards is to hit two pair or a set which is highly unlikely and is more like gambling than playing. Yes you need to gamble and/or get lucky to win big tourneys but I try to play tourneys like I play cash games. If I'm going to gamble I gamble to try and hit the nuts not the 2nd nuts or two pair.
8/7 suited is totally different and one of my fav hands.
If nobody has opened the pot you have to raise with that hand to try and eliminate any other flush chasers pre-flop. That way you will be up against bigger cards and you can play the board accordingly. If the pot has already been opened then just call.
They are connected so you can use the cards to hit 5 straits and 3 of them are the nuts, if you use both cards to make the strait they are all the nuts except one. My abosolute favorite non-paird hole cards are J/10 suited or not. Any strait you make with those cards is the nuts.
They are suited so you only need 3 board cards to make your flush. Unless you make your flush on the flop you can probably chase out non-flush hands with a 4 card flush on the board. If three suited cards hit the flop, anyone holding a big card of that suit will be hard to get rid off on the flop, it's easier to chase them out on the turn if another flush card doesn't come.
Same benefits apply to 8/7 as they do to K/7 as far as non-strait or non-flush plays. The nice thing about 8/7 or 9/8 suited is when they hit they typically don't help your oppenets who are prbably playing big cards. Small suited connecters are A/A and K/K killers, thats why I like to play them.
There were so many bs "suck outs" in that show I think the only reason you focused on this one was because the guy was wearing a Lakers jersey. Who give a fugg? It's poker, dumb is dumb, lucky is lucky, doesn't matter who's doing it. Most pro's, and ALL amatuers, would have played it the same way.
