In case you'd forgotten ...

Why it's a bad idea to limp with AA (especially if shortstacked):

PokerStars Pot-Limit Hold'em, $0.25 BB (9 handed) Hand History Converter Tool from FlopTurnRiver.com (Format: HTML)

Hero ($25.70)
UTG+1 ($8.85)

Preflop: Hero is SB with 5♣5♥.
1 fold, UTG+1 calls $0.25, 2 folds, MP3 calls $0.25, CO calls $0.25, 1 fold, Hero completes, BB checks.

Flop: ($1.25) 5♠K♥3♥ (Bingo!)
Hero bets $0.75, BB calls $0.75, UTG+1 raises to $2.25, MP3 folds, CO calls $2.25, Hero raises to $10.95, BB folds, UTG+1 calls $6.35 (All-In), CO folds.

I made the pot sized reraise (this is pot limit) both for value, and in order to make it wrong for anyone chasing the heart flush to come along.

Turn: ($21.45) 8♣ (2 players, 1 all-in)

River: ($21.45) 8♥ (2 players, 1 all-in)

I worried about the heart at first, but then realized it gave me my boat. Oops.

UTG+1 mucks A♣A♠
