Title: What are the odds of flopping quads?
Post by: TightEnd on June 23, 2005, 01:32:13 AM
Tonight at Luton

Phil Stein blind raises from first position early in rebuy period

Two callers

Flop QQ8

Phil leads out blind

One guy raises

Phil says "i'd better look then" and flat calls rest of hand

He has QQ and has flopped quads

No one at the table can tell me the odds of flopping quads

An answer please!!!

410/1 I believe, though my experience of playing people who call blind is they hit the nuts 1 in 2 times :D

what about BB holding 8,2 in and flopping 8,8,8 as happened in a live game last night?
is that more or less likely than me holding Kd,Jd and flopping Ad,Qd,10d a couple of weeks ago?

Red, I rarely challenge your maths, but surely more than 410/1? I tried to work it out, & it seemed about right, but it just sounds too low.

I am assuming this is only when you have a pair in your hand rather than 3 of a kind arriving on the flop.

Correct...QQ in hand

15/2 to hit a set and then you have two chances to hit the case Q which is a 1 in 49 shot followed by a 1 in 48 shot...but I would like to see the correct mathematical calculation

Oops, yes my assumption was PP in hole and paired board, probably beyond my fingers and toes to include the trips on board case card in your hand scenario  ;)


Title: Re: What are the odds of flopping quads?

it's trips on the board and holing the 4th I'm after

I realise why it seemed so wrong - low - now.

410/1 is IF you hold a the PP.

I think Adam's scenario would be the huge number I had in mind.

to finish the story the guy obviously checked the flop. turn was a 2 and, out of position he couldn't resist the temptation to bet. opponent passed 9,7 I dealt the river for fun and it would have been a 7. missed out on some chips there I think.

My Royal flush I mentioned made bugger all. who else is going to like an AQ10 diamond flop having limped without one of my cards in their hand?

It took me a while to click on that REAL monsteas - Royals, Quads - are rarely worth much, there is no action to be had unless you have a serial thief, a Camel, Penly, Thewy, Bradley type on the table.

The ones, perversely, that get paid best are the siily ones, 7-4 kinda jobbie catching hidden straights.

I did see a RF get a great payout the other week.... the other guy had quad Jacks.... the loser just about broke even with the 1k Bad beat jackpot.

Title: Re: What are the odds of flopping quads?

Now that WOULD be massive odds - quads & a RF in same pot! Guess you cold live on the Bad Beat tale for a while.

Sometimes betting it isn't a bad idea.

Yeah, but if trips flopped and any one of Thewy, Penly, Camel or At It Bradley bet, you'd beat 'em into the pot!

There are 3 different ways of flopping quad queens, QQx, QxQ,xQQ. These must being taken into the calculations. The odds on each of these is obviously the same but the problem can be worked out easily as 2/50*1/49 divded by 3(as there are 3 different permiatations of flopping it). This comes to 408.3333 to 1 meaning reds calculations are roughly correct- how dare you question the mans maths Tikay, there was a time we both used to answer maths questions on another forum eh red

Quads (using one of your pocket cards) from two non-pair cards - 9799/1

There was a time we used to play the same online stakes, now you are having a go at being a pro and I'm grinding it out at 2/4...cest la vie :D

what about flopping royal flush?

Let's say you hold the AJ of diamonds.  In order to flop a royal flush you need to hit the KQ10 of diamonds in no particular order on the first three cards.   You have three cards that you can hit on the first card rolled over, out of 50 remaining cards in the deck, so the odds of the first card rolled over being either the KQ or 10 of diamonds is 3/50. 

After you hit that card, you have two cards left to hit out of 49 remaining cards.  The odds the next card on the flop will be one of those is 2/49.

After you hit that card you must hit the remaining card, whatever it may be, out of 48 remaining cards in the deck, or 1/48.

The trick is, that you have to hit precisely all three of those cards.  we have figured out the odds of hitting each one individually.  To figure the odds of hitting all three of them precisely, you must multiply them all together.

50 x 49 x 48 = 117600

3 x 2 x 1 = 6

117600 / 6 = 19600 which means you will flop a royal if you hold two of the cards 1 time in every 19600, or 19599 to 1 against it.

Shamelessly nicked from a forum. I only know both times I got a Royal at Gala I got NO ACTION :D

Ah, point taken Ariston, but if you had read the thread (ooh-er) you would note I eventually clicked that the stat I was confusing it with was holding one Q in hand, and flopping 3. Which, spookily, Red has just completed his research on, & come up with 9799/1. As ever, Red anticipated my thoughts exactly. Hope he's not on my table tonight.

By the way, Crypto have just been on the phone to me. They have had a lot of requests from players asking to be on my table tonight. Thery have resolved it by making it a 48 man table. I'm delighted, the blinds will only come round every fortnight.

To flop a royal flush you have to hit 3 specific cards to go with your 2 suited pictures, eg 3/50*2/49*1/48= 19600-1

Considering that 2 hole cards and the three flop cards form a unique 5 card poker hand then the odds of flopping quads must be the same as being dealt quads in 5 card stud.

there are 2,598,960 different 5 card combinations
624 of these are 4 of a kind (each of the 13 Ranks * any one of the 48 other cards)

odds of flopping quads is therefore

4,164 - 1

That would be the odss of being dealt quads by the flop. If you already have a pocket pair then the odds of flopping quads would be the lower figure of ~410-1 quote above.

True... But the odds of recieving a pocket pair (17-1 or 5.55556%) and then improving to quads (407-1 or 0.2451%)

=0.0136% or approximately 7343 - 1


Title: Re: What are the odds of flopping quads?
Post by: Bongo on June 23, 2005, 05:33:50 PM
Which when combined with the 9799/1 of the quads with no PP give the same answer as in 5 stud.
