#1 3 people limp in MP, SB completes we have Jh9h in the BB
Flop comes Ax5h7h
SB bets, Hero ?
This is the usual spot to semi-bluff since we want to get money in the pot and drive out some other players. I raise this a lot more than I call since it might get us a free card on the next round if it is checked to us or if we check. I might fold if I know that MP players would limp a suited Ace and I'm likely to get reraised. 60%raise/15%call/25%fold. Plus, if we pair, we are in nicesih shape if we haven't gotten 3-bet on flop (SB has no Ace).
I'd even be more comfortable doing this if there was only one MP limper.
#2 UTG+1 raises MP calls, we hold KQh in the CO and call. Both blinds call.
Flop comes QsTh9s
UTG+1 bets, MP folds, Hero ?
Here we have the backdoor second nut-flush, top pair nice kicker and a gutshot. With all of our outs, we can only raise with the blinds to go. We aren't likely to get repoped by them and I call a 3-bet. We must thin the field at this point since we don't want flush draws or lower straights to outdraw us while we want to build a pot. This is not really a semi-bluff since we figure to have the best hand a huge number of times, but we still have a drawing hand wich might profit if we take a cheap (ie. one bet) card on the turn (and maybe induce a bluff on river).
#3 All fold to CO who raises, button calls, we 3-bet with JsTs in the BB. CO folds, button calls.
Flop comes KhQh3c
Preflop tomfoolery aside, we aren't in hot shape right now. We are almost never getting a free card from someone who cold called two times preflop. I'd check/call and reevaluate on turn a lot of the times since we are facing possible flush draws and do not have even one pair (and no FE).
#4 UTG limps, 3 in MP limp, we hold 8c7c and call on the button. Both blind calls.
Flops comes 769 rainbow
UTG bets, MP1 raises, all fold, Hero ?
This raise is pretty much always two pairs, trips or like us, a strong draw or someone getting frisky with two face cards (altough unlikely). Since we are only holding the dummy end of the draw and a second pair no kicker, I rarely reraise to shut out the blinds and maybe get this HU, but I only call if I know I can get at least one overcall to pad out the pot for future streets. Raise 30%, call50%, fold 20%. We need people in the pot here, and the original raise might thin the field for us, boosting our equity.
