Ok, stole this hand from an old thread... No info on villain.

$0.05/$0.10 No Limit Hold'em Cash, 6 Players

BTN: $16.49 (164.9 bb)
SB: $11.34 (113.4 bb)
BB: $8.59 (85.9 bb)
UTG: $6.70 (67 bb)
MP: $10.99 (109.9 bb)
Hero (CO): $10.97 (109.7 bb)

Preflop: Hero is CO with J A
UTG folds, MP raises to $0.40, Hero raises to $1, 3 folds, MP calls $0.60

Flop: ($2.15) 9 5 8 (2 players)
MP checks, Hero bets $1, MP calls $1

  • Preflop I'll guess villain is raising with the fowling range... 22+,A9s+,KTs+,QTs+,JTs,T9s,AQo+,KQo,QJo,JTo,T9o (171 Combinations)
  • Folding to our raise with... 88-22,JTo,T9o (63 Combinations)
  • Leaving him with the following to see the flop...99+,A9s+,KTs+,QTs+,JTs,T9s,AQo+,KQo,QJo (108 Combinations)
  • The flop excludes 5 combinations from his range with the presence of the 9s (103 Combinations)
  • I don't discredit anything from villains range by him checking since I know nothing about him. (still 103 Combinations)
  • My guess is that our villain is folding the following to a 1/2 pot size bet... KcJc,KdJd,KsJs,KTs,QTs,KcJd,KcJs,KdJc,KdJs,KhJc,Kh Jd,KhJs,KsJc,KsJd (20 Combinations)
  • So, with villain folding only 19.5% (20/103) of the time we make this bet, & us needing him to fold over 32% ($1/$3.15) of the time in a vacuum, this doesn't appear to be a profitable bluff.
