Hand reading is tough because people are fairly random in what they play.

Biggest things are stuff like "he made a big bet on the turn after limping preflop" - usually that means a player has a big draw or a hand > top pair, and mostly a big hand.

some good comments so far, and some good ideas about how to go about assigning ranges....I like retleftolc's idea that maybe a couple of y'all can post hands that you played where you were unsure of the range analysis....and we can all discuss it....you don't even have to give the whole hand if it's not pertinent - let's focus specifically on range assignment....

Sunny Mehta · #5 09-10-2007, 04:05 PM

one more comment is that I personally narrow hand ranges by looking at very specific tendencies wrt lines....specific action (check/call, check/raise, lead/call, etc.), vpip, pfr, 3-bet frequency, c-bet frequency, how they play the turn in and out of position, how they play the river in and out of position, etc. are all key things which aid me in narrowing an opponent's range....

Here's a hand that I analyzed recently by assigning a calling range for my opponent if I were to shove and used Pokerstove to calculate my equity against it. Hopefully you guys could provide comments on the positive/negative aspects of it. DISCLAIMER: preflop is probably bad.

EXAMPLE HAND:

Poker Stars
No Limit Holdem Ring game
Blinds: $0.25/$0.50
6 players
Converter

Stack sizes:
UTG: $41.25
Hero: $42.50
CO: $83.70
Button: $89.15
SB: $32.35
BB: $28.20

Pre-flop: (6 players) Hero is UTG+1 with 8[img]/images/graemlins/spade.gif[/img] 6[img]/images/graemlins/spade.gif[/img]
UTG calls, Hero raises to $2, 4 folds, UTG calls.

Flop: 9[img]/images/graemlins/spade.gif[/img] 3[img]/images/graemlins/diamond.gif[/img] 7[img]/images/graemlins/heart.gif[/img] ($4.75, 2 players)
UTG checks, Hero bets $3.5, UTG raises to $9 . . .

I haven't played many hands with this villain so I can't get a good read on his check-raising range.

However, up to this point I had been playing pretty aggressively and so I thought besides his obvious big hands he might also check-raise here sometimes as a bluff.

If he calls my jam, he might have something like:

9c9s,9d9s,9h9s,88-77,33,A9s,K9s,T8s,98s,97s, and A9o.

This range consists of:

A few combos of top set, middle and bottom set, top two, a couple combos of T8, the strongest top pairs, and occasionally he will have played a really weird overpair. He also might sometimes stacks off with second pair: 88.

My equity in this case is around 34%.

Given that I have 34% equity when called, he has to fold here greater than 30% of the time for me to start showing a profit on a shove.

Questions:

a) with such little info to act on, is it reasonable to assume that my opponent will fold > 30% of the time with this action sequence?
b) what is a decent estimate of an average opponent's check-raising range on this board with this preflop/flop action?
c) if I do shove, is the calling range I've assigned to my opponent a decent one?

Any comments on my assumptions or methods would be great.

I'd put him on A9,K9,q9,j9,109,88,A7 or possibly 1010,108,98
The CR to $9 - to me - seems that he wants to end the hand now.

Heres my take on the analysis of this hand, something which im working on.

I may be wrong, so dont take it for gospel.

So his range is wide on the flop, we can bet for value/take pot down. +EV bet.

[/b]Turn analysis:[/b]

Now here its probably wise to do two things, first give him a VERY TIGHT RANGE followed by a more optimistic/wider range.

Tight range:
Flush (9s8s will do for pokerstove, a flush is a flush and we have no redraw anyway so its fine)
Sets(QQ/TT/22)
2pair but ONLY WITH REDRAW TO FLUSH, Qs or Ts).

Poker stove raw range: QQ,TT,22,9s8s,QcTs,QdTs,QhTs,QsTc,QsTd,QsTh

Equity here: 7%

Wider Range
Same as tight range but we add others now.
2pair without redraws(QTo),
TPTK+Redraw,
TPTK+no redraw

Stove range: QQ,TT,22,AQs,AQo,QTo

Equity here: 37% (<2:1 required).

Now if we interpolate this range of %7 to 37% and look at our pot odds.

$7 pot + $4 bet + $12 shove =$23 vs $8 to call. 3:1 pot odds.

Optimistic range, easy call.
Tight range, Easy fold.

However the wider range isnt very wide, due to the line he took i feel he has FD alot more than say KQ here hence i discounted KQ to add more weight to flush.

So i dont mind a fold or call in this spot due to odds, however you will see a flush alot. Will it be more that 3 out of 4 times?

Since I spoke up I'll try one . . .

A dry one- Vill is 44/13/1.35 over 136 hands.

PokerStars No-Limit Hold'em, $0.25 BB (5 handed) Hand History Converter Tool from FlopTurnRiver.com (Format: 2+2 Forums)

MP ($24.50)
Hero ($37.75)
SB ($34.60)
BB ($49.85)
UTG ($16)

Preflop: Hero is Button with K[img]/images/graemlins/spade.gif[/img], A[img]/images/graemlins/spade.gif[/img].
2 folds, Hero raises to $1, 1 fold, BB calls $0.75.

Flop: ($2.10) 7[img]/images/graemlins/spade.gif[/img], 5[img]/images/graemlins/diamond.gif[/img], K[img]/images/graemlins/club.gif[/img] (2 players)
BB checks, Hero bets $1.5, BB calls $1.50.

Assign a range.

I know this is a sad starter, but I searched my database(which made me sad- I suck, good thing others suck more) for others and had a hard time finding good ones. Probably because im tired.

Any one pair better than 44 and worse than AA, a set, any 2 pair, 86s, 64s, 98s.
