PokerStars 1/2 Hold'em (10 handed)

Preflop: Humphrind is MP3 with K:diamond:, K:heart:.
UTG folds, UTG+1 folds, UTG+2 folds, MP1 folds, MP2 folds, Humphrind raises, CO folds, Button folds, SB calls, BB calls.

Flop: (6 SB) A:diamond:, 4:spade:, Q:club: (3 players)
SB checks, BB checks, Humphrind bets, SB calls, BB raises, Humphrind calls, SB calls.

Turn: (6 BB) 9:spade: (3 players)
SB checks, BB bets, Humphrind folds, SB calls.

River: (8 BB) 6:spade: (2 players)
SB checks, BB checks.

Final Pot: 8 BB

Fold to the flop c/r. However, in a live game you might make this call (and fold to the turn, like you did) just to avoid drawing bluffs.

The amazing part is this:

SB had KK
BB had AJ and won the hand.

At this level, a check/raise is almost always Top Pair or better. Sometimes it's a strong draw (particulalry if the raiser can pump the pot after callers), but without a strong draw on the board it's a really easy read.

good read!
